如何在 GoogleTest 中运行特定的测试用例

How to run specific test cases in GoogleTest(如何在 GoogleTest 中运行特定的测试用例)

问题描述

我正在尝试为我的项目编写一个函数/方法，它会询问用户您要运行哪些所有测试用例?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

那么，现在的挑战是在运行项目时，它应该提示我您想要执行的所有测试用例是什么?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，并且应该排除 Test_Cases_2 to .... 中的所有其他测试用例.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，有一个方法叫做test_case_to_run_count()；但是所有的 test cases 都使用 Test_F() 方法注册.所以，我做了很多分析，但仍然没有找到任何解决方案.请帮帮我.

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 用于运行 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，其值接受 * 和 ?用于匹配多个测试的通配符.我认为它会解决您的问题.

To run only some unit tests you could use --gtest_filter=Test_Cases1* command line option with value that accepts the * and ? wildcards for matching with multiple tests. I think it will solve your problem.

更新:

嗯，问题是如何运行特定的测试用例.将 gtest 与您的 GUI 集成是另一回事，我无法真正评论，因为您没有提供您的方法的详细信息.不过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. 通过使用 --gtest_list_tests
运行测试来获取所有测试用例
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
