Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, apparatus, computer equipment, and storage medium for calculating conditional branch coverage. Background Art

[0002] Generally speaking, in order to ensure project quality, a project needs to undergo several rounds of testing. In addition to common unit testing, integration testing, functional testing, and regression testing, we also need code coverage testing to ensure the integrity and comprehensiveness of code testing. If the code coverage test does not meet the standards, it means that some code has not been fully tested, and these untested codes are likely to contain bugs, resulting in the project quality cannot be guaranteed. This shows the importance of code coverage testing.

[0003] Commonly used statistical metrics for code coverage include function coverage, condition coverage, branch coverage, and statement coverage. Statement coverage and function coverage are calculated by dividing the number of covered statements and functions by the total number of statements and functions, while conditional branch coverage is calculated by dividing the number of covered conditions and branches by the total number of conditions and branches. Conditional branch coverage is generally calculated by dividing the number of conditional branches covered by the code by the total number of conditional branches. However, in some cases, it may be unnecessary or impossible to cover the conditional branches of some code, resulting in inaccurate and unreliable coverage reports that cannot meet the code testing needs of some high-tech projects.

[0004] Currently, the way conditional branch coverage is calculated is not very accurate. Summary of the Invention

[0056] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0057] In one embodiment, Figure 1 As shown, a method for calculating conditional branch coverage is provided. This embodiment uses the method applied to a terminal as an example for illustration. It is understandable that the method can also be applied to a server, or to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0058] Step 102: Obtain the code type of the uncovered conditional branch code line in the target code, and obtain the comment information corresponding to the uncovered conditional branch code line according to the code type.

[0059] The code type refers to the conditional branch statement type of the conditional branch code line, including if statements (condition / decision), switch statements (switch / case), ternary operators, etc. The uncovered conditional branch code lines are obtained by calculating the basic conditional branch coverage of the target code using existing code coverage calculation methods.

[0060] Specifically, based on the test requirements, annotation information is first added to the target code for the code lines that do not need to be covered. The annotation information is used to indicate the exclusion of the corresponding conditional branch code line or the exclusion of a branch of the corresponding conditional branch code line. Then, the target code is subjected to conditional branch coverage calculation using the existing code coverage calculation method. While obtaining the basic conditional branch coverage of the target code, all uncovered conditional branch code lines in the target code can be determined. For example, Bullseye software is used to calculate the conditional branch coverage of the target code. The code type of each uncovered conditional branch code line in the target code is identified, and the annotation information corresponding to each uncovered conditional branch code line is detected and identified based on the code type.

[0061] Step 104 : Obtain coverage parameters corresponding to the uncovered conditional branch code lines according to the annotation information corresponding to the uncovered conditional branch code lines.

[0062] The absolute value of the coverage parameter represents the number of units corresponding to a conditional branch code line when counting code statements. The coverage parameter is usually 0, -1, and -2.

[0063] Specifically, based on the comment information corresponding to an uncovered conditional branch code line, it can be determined whether the uncovered conditional branch code line is excluded. Exclusion means that the excluded part does not need to be calculated into the code coverage. When conditional branch code lines of some code types are excluded, it is also divided into two situations: all code lines are excluded and one branch of the code line is excluded. The comment information corresponding to conditional branch code lines of different code types is different. Therefore, the code type and exclusion situation can be determined based on the comment information of the uncovered conditional branch code line, thereby determining the coverage parameters corresponding to the uncovered conditional branch code line. Similarly, the coverage parameters corresponding to each uncovered conditional branch code line can be determined.

[0064] Step 106 , calculating the conditional branch coverage rate corresponding to the target code based on the coverage parameters corresponding to the uncovered conditional branch code lines and the total number of conditional branch code lines in the target code.

[0065] The total number of conditional branch code lines refers to the number of code lines of the conditional branch type in the target code.

[0066] Specifically, the coverage parameters corresponding to each uncovered conditional branch code line are added to obtain a coverage parameter sum, and then the coverage parameter sum is added to the total number of conditional branch code lines in the target code to obtain the total number of covered conditional branch code lines and excluded conditional branch code lines in the target code. The total number of covered conditional branch code lines and excluded conditional branch code lines in the target code is taken as the conditional branch coverage number corresponding to the target code, and the ratio of the conditional branch coverage number corresponding to the target code to the total number of conditional branch code lines in the target code is taken as the conditional branch coverage rate corresponding to the target code.

[0067] In the above-mentioned conditional branch coverage calculation method, the code type of the uncovered conditional branch code line in the target code is obtained, and the comment information corresponding to the uncovered conditional branch code line is obtained based on the code type; the coverage parameter corresponding to the uncovered conditional branch code line is obtained based on the comment information corresponding to the uncovered conditional branch code line; and the conditional branch coverage corresponding to the target code is calculated based on the coverage parameter corresponding to the uncovered conditional branch code line and the total number of conditional branch code lines in the target code. This method can eliminate conditional branch code lines that do not need to be counted based on the comment information corresponding to each conditional branch code line, thereby improving the calculation accuracy of the conditional branch coverage.

[0068] In one embodiment, a method for obtaining uncovered conditional branch code lines in a target code includes: obtaining a basic conditional branch coverage of the target code; and obtaining uncovered conditional branch code lines in the target code according to the basic conditional branch coverage of the target code.

[0069] Specifically, Bullseye is used to calculate the basic conditional branch coverage of the target code. Bullseye can obtain the total number of conditional branch code lines in the target code and all uncovered conditional branch code lines.

[0070] In one embodiment, before obtaining the code type of the uncovered conditional branch code line in the target code and obtaining the comment type corresponding to the uncovered conditional branch code line according to the code type, it also includes: obtaining each conditional branch code line in the target code and identifying the code type of each conditional branch code line in the target code; determining the comment type corresponding to each conditional branch code line according to the code type of each conditional branch code line, and adding comment information to each conditional branch code line according to the comment type corresponding to each conditional branch code line in the target code.

[0071] Further, determining a comment type corresponding to each conditional branch code line according to the code type of each conditional branch code line, and adding comment information to each conditional branch code line according to the comment type corresponding to each conditional branch code line in the target code, including: if the code type of a conditional branch code line is a first code type, determining that a conditional branch code line corresponds to a first comment type, the first comment type includes first comment information, second comment information, third comment information, and fourth comment information, adding one of the first comment information, second comment information, third comment information, and fourth comment information to the conditional branch code line, or not adding any comment information; If the code type of a conditional branch code line is the second code type, then it is determined that a conditional branch code line corresponds to the second comment type, and the second comment type includes fifth comment information, and the fifth comment information is added to a conditional branch code line, or no comment information is added; the first comment information is used to indicate the exclusion of the first part of the corresponding conditional branch code line, the second comment information is used to indicate the exclusion of the second part of the corresponding conditional branch code line, the third comment information is used to indicate the exclusion of the first part or the second part of the corresponding conditional branch code line, the fourth comment information is used to indicate the exclusion of the first part and the second part of the corresponding conditional branch code line, and the fifth comment information is used to indicate the exclusion of the corresponding conditional branch code line.

[0072] Specifically, first formulate a set of exclusion rules according to the test requirements, and add the comment information covexclude to the corresponding condition / decision / switch code statements that need to be excluded, so that the conditional branch coverage can be recalculated by reading the relevant comments later. There are two methods for adding comment information.

[0073] The first method of adding comment information is line exclusion (also known as line exclusion). Exclusion is completed by adding relevant comments after the code line, realizing single-line exclusion T / F. Another method is batch exclusion T / F. Relevant comments are added before and after the code segment that needs to be excluded T / F. The rules for line-by-line exclusion in the first case are shown in Table 1:

[0074]

[0075] Table 1

[0076] The application example of the first method of adding annotation information is as follows Figure 2 shown.

[0077] The second method of adding annotation information is batch exclusion (also known as batch exclusion). Add comments / **COVEXCLUDE start** / and / **COVEXCLUDE end** / before and after the code segment to be excluded to complete the batch exclusion T / F of this code segment. The rules are shown in Table 2:

[0078]

[0079]

[0080] Table 2

[0081] The application example of the second method of adding annotation information is as follows Figure 3 shown.

[0082] In the above table, condition / decision refers to the first code type, T and F respectively represent a branch of the conditional branch code line, T represents the first part of the conditional branch code line (that is, the true branch of the conditional branch code line), F represents the second part of the conditional branch code line (that is, the false branch of the conditional branch code line), covexcludeT, covexcludeF, covexcludeTorF, and covexcludeTF respectively represent the first annotation information, second annotation information, third annotation information, and fourth annotation information corresponding to the first code type, covexcludeT indicates that the T branch of the corresponding code line is excluded when calculating the coverage, covexcludeF indicates that the F branch of the corresponding code line is excluded when calculating the coverage, covexcludeTorF indicates that the T branch or F branch of the corresponding code line is excluded when calculating the coverage, and covexcludeTF indicates that the T branch and F branch of the corresponding code line are excluded when calculating the coverage. If a condition / decision conditional branch code line does not need to be excluded as a whole, no annotation information is added to the conditional branch code line. Switch / case refers to the second code type. These two statements do not involve partial exclusion when excluding. To exclude, exclude the entire code line. X represents the entire conditional branch code line, covexcludeC represents the fifth comment information corresponding to the second code type, and covexcludeC indicates excluding the corresponding code line. If a switch / case conditional branch code line does not need to be excluded, no comment information is added to the conditional branch code line.

[0083] In this embodiment, each conditional branch code line in the target code is obtained and the code type of each conditional branch code line in the target code is identified; the comment type corresponding to each conditional branch code line is determined based on the code type of each conditional branch code line; and comment information is added to each conditional branch code line based on the comment type corresponding to each conditional branch code line in the target code. Different comment information can be added to code lines according to different test requirements, thereby excluding code lines that do not need to be calculated during the subsequent code coverage calculation process, thereby improving the calculation accuracy of the conditional branch coverage rate.

[0084] In one embodiment, obtaining coverage parameters corresponding to uncovered conditional branch code lines according to comment information corresponding to uncovered conditional branch code lines includes: if the code type of a conditional branch code line is a first code type, obtaining the uncovered type corresponding to the uncovered conditional branch code line, the uncovered type being divided into first partial coverage, second partial coverage, or full uncovered; if the uncovered type corresponding to the uncovered conditional branch code line is first partial coverage, and the comment information corresponding to the uncovered conditional branch code line is second comment information, third comment information, or fourth comment information, determining that the coverage parameter corresponding to the uncovered conditional branch code line is 0; if the code type of the uncovered ... a first code type, the uncovered type being a second code type, the uncovered type being a third code type, or a fourth code type If the corresponding uncovered type is the first partial coverage, and the comment information corresponding to the uncovered conditional branch code line is not the second comment information, the third comment information or the fourth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -1; if the corresponding uncovered type is the second partial coverage, and the comment information corresponding to the uncovered conditional branch code line is the first comment information, the third comment information or the fourth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be 0; if the corresponding uncovered type is the second partial coverage, and the comment information corresponding to the uncovered conditional branch code line is not the first comment information , the third comment information or the fourth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -1; if the uncovered type corresponding to the uncovered conditional branch code line is fully uncovered, and the comment information corresponding to the uncovered conditional branch code line is the fourth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be 0; if the uncovered type corresponding to the uncovered conditional branch code line is fully uncovered, and the comment information corresponding to the uncovered conditional branch code line is the first comment information, the second comment information or the third comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -1; if the uncovered type corresponding to the uncovered conditional branch code line is fully uncovered If the code type is fully uncovered, and the comment information corresponding to the uncovered conditional branch code line is not the first comment information, the second comment information, the third comment information or the fourth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -2; if the code type of a conditional branch code line is the second code type, and the comment information corresponding to the uncovered conditional branch code line is the fifth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be 0; if the code type of a conditional branch code line is the second code type, and the comment information corresponding to the uncovered conditional branch code line is not the fifth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -1.

[0085] Specifically, determine the code type. If the code line type is condition / decision, then the code line accounts for 2 in totalcov (also known as the total number of cov or total coverage). Totalcov refers to the total number of conditional branch code lines assuming full coverage of the target code, that is, the total number of conditional branch code lines in the target code. First, set newcov = totalcov, and then see if there is any line or batch comment covexclude information. If so, determine newcov-1 / -0 / -2 according to the corresponding situation in the table below. If not, directly use newcov-2. If the type is switch / case, then it accounts for 1 in the total number of cov. Then see if there is any comment covexclude information. If so, determine newcov-1 / -0. If not, directly use newcov-1.

[0086] As shown in Table 3, conditional / decision code lines that do not cover T, F, or TF are considered uncovered. In actual coverage, coverage of TF and X indicates that the current code line is already covered, so they are not considered uncovered conditional branch code lines and their corresponding coverage parameters are 0.

[0087]

[0088] Table 3

[0089] In one embodiment, the conditional branch coverage rate corresponding to the target code is calculated based on the coverage parameters corresponding to the uncovered conditional branch code lines and the total number of conditional branch code lines in the target code, including: adding the total number of conditional branch code lines in the target code and the coverage parameters corresponding to each uncovered conditional branch code line in the target code to calculate the conditional branch coverage number corresponding to the target code; and calculating the conditional branch coverage rate corresponding to the target code based on the ratio of the conditional branch coverage number corresponding to the target code to the total number of conditional branch code lines in the target code.

[0090] Specifically, by traversing the comment information and code type corresponding to each line of code, newcov-1 / -2 / -0 can be used to repeatedly calculate the conditional branch coverage after excluding some conditional branch code lines. The number of calculations is equal to the number of uncovered conditional branch code lines. Finally, the conditional branch coverage rate is calculated by dividing the final calculated newcov by totalcov.

[0091] In one embodiment, a method for calculating conditional branch coverage includes:

[0092] Obtain each conditional branch code line in the target code and identify the code type of each conditional branch code line in the target code; if the code type of a conditional branch code line is a first code type, determine that the conditional branch code line corresponds to a first comment type, the first comment type includes first comment information, second comment information, third comment information and fourth comment information, and add one of the first comment information, second comment information, third comment information and fourth comment information to the conditional branch code line, or do not add any comment information; if the code type of a conditional branch code line is a second code type, determine that the conditional branch code line corresponds to a second comment type, the second comment type includes fifth comment information, and add the fifth comment information to the conditional branch code line, or do not add any comment information; the first comment information is used to indicate the exclusion of a first part of the corresponding conditional branch code line, the second comment information is used to indicate the exclusion of a second part of the corresponding conditional branch code line, the third comment information is used to indicate the exclusion of the first part or the second part of the corresponding conditional branch code line, the fourth comment information is used to indicate the exclusion of the first part and the second part of the corresponding conditional branch code line, and the fifth comment information is used to indicate the exclusion of the corresponding conditional branch code line.

[0094] If the code type of a conditional branch code line is the first code type, obtain the uncovered type corresponding to the uncovered conditional branch code line, and the uncovered type is divided into the first partial coverage, the second partial coverage or the full uncovered; if the uncovered type corresponding to the uncovered conditional branch code line is the first partial coverage, and the comment information corresponding to the uncovered conditional branch code line is the second comment information, the third comment information or the fourth comment information, then determine that the coverage parameter corresponding to the uncovered conditional branch code line is 0; if the uncovered type corresponding to the uncovered conditional branch code line is the first partial coverage, and the comment information corresponding to the uncovered conditional branch code line is not the second comment information information, the third annotation information or the fourth annotation information, then it is determined that the coverage parameter corresponding to the uncovered conditional branch code line is -1; if the uncovered type corresponding to the uncovered conditional branch code line is the second partial coverage, and the annotation information corresponding to the uncovered conditional branch code line is the first annotation information, the third annotation information or the fourth annotation information, then it is determined that the coverage parameter corresponding to the uncovered conditional branch code line is 0; if the uncovered type corresponding to the uncovered conditional branch code line is the second partial coverage, and the annotation information corresponding to the uncovered conditional branch code line is not the first annotation information, the third annotation information or the fourth annotation information, then it is determined that the uncovered conditional branch The coverage parameter corresponding to the code line is -1; if the uncovered type corresponding to the uncovered conditional branch code line is fully uncovered, and the comment information corresponding to the uncovered conditional branch code line is the fourth comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be 0; if the uncovered type corresponding to the uncovered conditional branch code line is fully uncovered, and the comment information corresponding to the uncovered conditional branch code line is the first comment information, the second comment information or the third comment information, then the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -1; if the uncovered type corresponding to the uncovered conditional branch code line is fully uncovered, and the uncovered conditional branch code line has the first comment information, the second comment information or the third comment information. If the comment information corresponding to the conditional branch code line is not the first comment information, the second comment information, the third comment information or the fourth comment information, the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -2; if the code type of a conditional branch code line is the second code type, and the comment information corresponding to the uncovered conditional branch code line is the fifth comment information, the coverage parameter corresponding to the uncovered conditional branch code line is determined to be 0; if the code type of a conditional branch code line is the second code type, and the comment information corresponding to the uncovered conditional branch code line is not the fifth comment information, the coverage parameter corresponding to the uncovered conditional branch code line is determined to be -1.

[0095] The conditional branch coverage number corresponding to the target code is calculated by adding the total number of conditional branch code lines in the target code and the coverage parameter corresponding to each uncovered conditional branch code line in the target code; the conditional branch coverage rate corresponding to the target code is calculated based on the ratio of the conditional branch coverage number corresponding to the target code and the total number of conditional branch code lines in the target code.
