In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Example one
The embodiment provides a test method based on code coverage, as shown in fig. 1, the method includes:
step S101 is first executed: and performing instrumentation monitoring on the first source code to be tested to obtain a second source code to be tested, wherein the second source code to be tested comprises a method code.
Specifically, the first source code to be tested may be a code or a code segment of the whole program, instrumentation monitoring is to insert some probes (also called "detectors", which are essentially code segments for information acquisition and may be assignment statements or function calls for acquiring coverage information) into the program on the basis of ensuring the original logic integrity of the program to be tested, and by executing the probes and throwing out characteristic data of program operation, through analyzing the data, control flow and data flow information of the program can be obtained, and further dynamic information such as logic coverage and the like can be obtained, thereby realizing the method for testing. The method of monitoring pile insertion may be an existing method, and is not particularly limited herein.
As an optional implementation manner, a code deployment manner may be adopted to perform instrumentation monitoring on the first source code to be tested, so as to improve accuracy and efficiency of instrumentation monitoring.
Specifically, the instrumentation monitoring can be performed by setting the trigger mechanism as a code deployment trigger mechanism and automatically triggering the code deployment.
Then, step S102 is executed: and testing the second source code to be tested and recording test information, wherein the test information comprises code coverage rate information.
Specifically, the test method may be an automation test, a functional test unit test, an interface test, a UI automation test, and the like, and the test information may include control flow, data flow information, and coverage rate information of the program, which is not specifically limited herein.
Step S103 is performed next: and obtaining the mapping relation between the method codes and the corresponding functions.
Specifically, the second source code to be tested may include a plurality of methods, and these methods all have corresponding functions, for example, the methods include A, B, C, where the method a is used to implement user login, the method B is used for user addition operation, and the method C is used for user deletion operation. Through the mapping relation, the functions of the codes can be accurately positioned. The specific method for obtaining the mapping relationship can be obtained by executing the code in the method or analyzing the annotation of the code.
In order to improve the efficiency of obtaining the mapping relationship, in an embodiment, the mapping relationship between the method code and the corresponding function may be obtained by automatically parsing a code annotation with a script, and the script language may be Ruby, python, shell, or the like.
And step S104 is executed again: and obtaining the codes of the tested function points and the codes of the untested function points according to the test information and the mapping relation.
Specifically, the test condition may be analyzed according to test information in the test of the second source code to be tested, and then the code of the tested function point and the code of the untested function point may be determined according to the analysis result and the mapping relationship.
In an alternative embodiment, the test information includes coverage information, and the code for obtaining the tested function points and the code for obtaining the untested function points may be implemented by:
counting the coverage rate information to obtain a coverage rate counting result;
analyzing the coverage rate statistical result to determine tested codes and untested codes;
obtaining the codes of the tested function points according to the mapping relation and the tested codes;
and obtaining the code of the untested function point according to the mapping relation and the untested code.
In a specific implementation process, a coverage rate statistical tool may be used to perform statistics on the coverage rate information, so as to obtain a coverage rate statistical result, where the coverage rate statistical tool may be Jacoco corresponding to a Java language and PHPCoverage corresponding to a PHP language.
Because function testers have no code reading capability, and cannot judge whether the executed test completely covers the code after the test is passed, and cannot accurately position untested function points by using a code coverage rate tool, the embodiment of the invention provides a test method based on code coverage rate, which can automatically analyze annotations in the code by using a script, obtain the mapping relation between the method code and the function, and obtain the relevant codes of tested function points and untested function points according to the test information and the mapping relation in the test process, thereby guiding to carry out complete test, improving the effectiveness of the test effect, quickly and completely covering all function points, and achieving the effect of completely covering the test.
