Problems solved by technology

The current situation is that students can easily write Java unit tests with the help of Eclipse, but there are the following imperfections: 1. Students cannot evaluate the strength of the test cases they write; 2. Teachers cannot evaluate whether students write seriously; 3. Only Arranging free exercises, programming exams where unit tests cannot be organized
It is precisely because of the relative isolation between teachers and students in the white box test, it is difficult for teachers to collect students' understanding of test task points, and it is difficult to improve teaching content based on actual feedback
Therefore, the traditional test teaching method has been unable to meet the training objectives of excellent test developers

Embodiment Construction

[0075] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.

[0076] figure 1 It is a flowchart of a teaching feedback method for Java unit testing based on program static analysis in an embodiment of the present invention.

[0077] A kind of Java unit test teaching feedback method based on program static analysis is characterized in that, comprises the following steps:

[0078] S101 Static structure analysis of source program code. Use the Soot framework to analyze the control flow of the bytecode program compiled by the Java source program, obtain the control flow data of the source program, and convert them into a common data format and store them in a file. Finally, for each function of each class of the source program, a JSON format file will be obtained, which records the intermediate instruction set of each node of the static structure of the source ...

Abstract

The invention provides a Java unit test teaching feedback method based on program static analysis, comprising the following steps: 1) source program code static structure analysis; 2) source program test requirement generation; 3) Java unit test case writing; 4) Test case coverage data collection; 5) Summary statistics of test cases and coverage data; 6) Visual display of source program static structure and coverage data; 7) Execution process display of a single test case on source program static structure. The present invention solves the problem that the Java unit test teaching task is difficult to practice and evaluate in the current software test course, provides a platform for programming practice and automatic evaluation and visual display of the Java unit test, and greatly improves the practice and evaluation efficiency of the teaching task. It helps teachers improve teaching content based on practice feedback, and helps students continuously improve their ability to write test cases based on practice feedback.

Description

technical field [0001] The invention belongs to the technical field of software testing, and in particular relates to a teaching feedback method for Java unit testing based on program static analysis. Background technique [0002] Software testing is an exploratory activity designed to help software practitioners assess the quality status of the software under test. In the complete software development process, software testing activities run through and occupy most of the time of software development projects, so excellent testers are in great demand in the industry. As a core professional course in the software engineering education system, software testing trains students to attach importance to software quality and code quality, acts as a bridge connecting education and industry, and trains excellent developers and testers for the IT industry. [0003] White-box testing is an important task in software testing teaching, and we usually take Java unit testing as an exampl...
