如何在GoogleTest中运行特定测试用例 [英] How to run specific test cases in GoogleTest

问题描述

我想为我的项目写一个函数/方法，它会询问用户你要运行哪些测试用例？
它看起来像下面...，

I am trying to write a function/method for my project, which will ask to user which all test cases are you going to run? It looks like below...,

Test_Cases_1
         |_TestNo1
         |_TestNo2....so on
Test_Cases_2
         |_TestNo1
         |_TestNo2....so on
....
....so on
Test_Cases_N
         |_TestNo1
         |_TestNo2....so on

现在的挑战是，在运行项目时，它应该提示我，你想要执行的所有测试用例？
如果我选择 Test_Cases_1 和 Test_Cases_N 。然后它应该执行这两个测试用例，并应该将所有其他从 Test_Cases_2到.... 。在结果窗口中，我也想看到 Test_Cases_1 和 Test_Cases_N 的结果。

So, now the challenge is while running the project it should prompt me what all test cases you would like to execute? If I select Test_Cases_1 and Test_Cases_N. Then it should execute these two test cases and should exclude all other from Test_Cases_2 to ..... In result window also I would like to see the results of Test_Cases_1 and Test_Cases_N.

所以，如果我看到GoogleTest，有一个方法 test_case_to_run_count（）;
但是所有的测试用例都是通过Test_F（）方法注册的。
所以，我做了很多分析，但仍然没有找到任何解决方案。
请帮助我。

So, if I will see the GoogleTest, there is a method called test_case_to_run_count(); But all the test cases are getting registered with Test_F() method. So, I did lots of analysis, but still did not find any solution. Please help me.

推荐答案

您可以使用高级选项来运行Google测试。

You could use advanced options to run Google tests.

要仅运行一些单元测试，您可以使用 - gtest_filter = Test_Cases1 * 命令行选项，值为正则表达式。我认为这将解决你的问题。

To run only some unit tests you could use --gtest_filter=Test_Cases1* command line option with value which is regular expression. I think it will solve your problem.

UPD：

运行特定测试用例。将gtest与您的GUI集成是另一回事，我不能真正评论，因为您没有提供您的方法的详细信息。但我相信以下方法可能是一个好的开始：

Well, the question was how to run specific test cases. Integration of gtest with your GUI is another thing, which I can't really comment, because you didn't provide details of your approach. However I believe the following approach might be a good start:

1. 通过运行测试获取所有测试用例 - gtest_list_tests


2. 将此数据解析到您的GUI中


3. 选择要运行的测试用例


4. 使用选项 - gtest_filter 运行测试可执行文件

1. Get all testcases by running tests with --gtest_list_tests
2. Parse this data into your GUI
3. Select test cases you want ro run
4. Run test executable with option --gtest_filter
