How to run specific test cases in GoogleTest
提问by Rasmi Ranjan Nayak
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...,
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？看起来像下面...，
Test_Cases_1
|_TestNo1
|_TestNo2....so on
Test_Cases_2
|_TestNo1
|_TestNo2....so on
....
....so on
Test_Cases_N
|_TestNo1
|_TestNo2....so on
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_1and 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_1and Test_Cases_N.
所以，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从Test_Cases_2 to ..... 在结果窗口也是我希望看到的结果Test_Cases_1和Test_Cases_N。
So, if I will see the GoogleTest, there is a method called test_case_to_run_count();
But all the test casesare getting registered with Test_F() method.
So, I did lots of analysis, but still did not find any solution.
Please help me.
所以，如果我会看到 GoogleTest，有一个方法叫做test_case_to_run_count(); 但是所有这些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。请帮我。

You could use advanced optionsto run Google tests.
您可以使用高级选项来运行 Google 测试。
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.
要仅运行某些单元测试，您可以使用--gtest_filter=Test_Cases1*命令行选项，其值接受*和?通配符以匹配多个测试。我认为它会解决你的问题。
UPD:
更新：
Well, the question was how to runspecific 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:
那么，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。但是我相信以下方法可能是一个好的开始：
- Get all testcases by running tests with
--gtest_list_tests - Parse this data into your GUI
- Select test cases you want ro run
- Run test executable with option
--gtest_filter
- 通过运行测试来获取所有测试用例
--gtest_list_tests - 将此数据解析到您的 GUI 中
- 选择你想要运行的测试用例
- 使用选项运行测试可执行文件
--gtest_filter

Summarising @Rasmi Ranjan Nayak and @nogard answers and adding another option:
总结@Rasmi Ranjan Nayak 和@nogard 的答案并添加另一个选项：
On the console
在控制台上
You should use the flag --gtest_filter, like
你应该使用标志--gtest_filter，比如
--gtest_filter=Test_Cases1*
(You can also do this in Properties|Configuration Properties|Debugging|Command Arguments)
（您也可以在属性|配置属性|调试|命令参数中执行此操作）
On the environment
关于环境
You should set the variable GTEST_FILTERlike
你应该GTEST_FILTER像这样设置变量
export GTEST_FILTER = "Test_Cases1*"
On the code
在代码上
You should set a flag filter, like
你应该设置一个标志filter，比如
::testing::GTEST_FLAG(filter) = "Test_Cases1*";
such that your main function becomes something like
这样你的主要功能就变得像
int main(int argc, char **argv) {
::testing::InitGoogleTest(&argc, argv);
::testing::GTEST_FLAG(filter) = "Test_Cases1*";
return RUN_ALL_TESTS();
}
See section Running a Subset of the Testsfor more info on the syntax of the string you can use.
有关您可以使用的字符串语法的更多信息，请参阅运行测试的子集部分。

Finally I got some answer,
::test::GTEST_FLAG(list_tests) = true;//From your program, not w.r.t console.
最后我得到了一些答案，
::test::GTEST_FLAG(list_tests) = true;//来自你的程序，而不是控制台。
If you would like to use --gtest_filter =*;/* =*, =xyz*... etc*/// You need to use them in Console.
如果您想使用--gtest_filter =*;/* =*, =xyz*... etc*/// 您需要在控制台中使用它们。
So, my requirement is to use them from the program not from the console.
所以，我的要求是从程序而不是从控制台使用它们。

Finally I got the answer for updating the same in from the program.
最后我得到了从程序中更新相同内容的答案。
::testing::GTEST_FLAG(filter) = "*Counter*:*IsPrime*:*ListenersTest.DoesNotLeak*";//":-:*Counter*";
InitGoogleTest(&argc, argv);
RUN_ALL_TEST();
So, Thanks for all the answers.
所以，感谢所有的答案。
You people are great.
你们人真好。
