Embodiment Construction

[0042] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0043] the following figure 1 Shown is a schematic flow chart of the data flow testing method based on key point guidance in the present invention, such as figure 1 . It includes the following steps:

[0044] Step 1: Obtain the definition-use pair in the program to be tested through a standard data flow analysis method. The definition-use pair means that there is a control flow path always from the definition control flow node of the variable to the use control flow node of the same variable , and there is no redefinition of the variable between the define control flow ...

Abstract

The invention discloses a data stream testing method based on key point guidance. The method comprises the following steps that: through a standard data stream analysis method, obtaining a definition-use pair in a program to be tested; according to a control stream analysis method, analyzing key points in the definition-use pair; inputting the definition-use pair and the key point into a symbol actuator; using a path searcher based on the key point to guide a symbol in execution by the symbol actuator; if a symbol execution path covers the definition-use pair, returning a test case corresponding to the symbol execution path, otherwise, continuously executing S4 until the corresponding test case is generated for all definition-use pairs or all symbol execution paths finish being executed, and ending the execution of the symbol actuator; and according to a symbol execution result, carrying out statistics on a coverage rate. The invention also discloses a data stream testing system basedon the key point guidance.

Description

technical field [0001] The invention relates to the field of computer software testing, in particular to a data flow testing method based on key point guidance and a testing system thereof. Background technique [0002] With the development of the Internet, the application of computers in all walks of life has gradually deepened. Computer software not only plays an irreplaceable role in large commercial systems, but also plays an important role in various industrial systems. As the scale of computer software systems continues to grow, large-scale e-commerce, nuclear power, aerospace, orbit control and other fields have put forward higher requirements for the reliability of software systems. According to a survey conducted by the University of Cambridge in 2013, the global annual expenditure on solving software errors is as high as 312 billion U.S. dollars, and each programmer spends 50% of the time on average to find and solve software errors. It can be seen that avoiding ...
