How to run specific test cases in GoogleTest

Question

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         


        

Answer 1

Finally I got some answer, ::test::GTEST_FLAG(list_tests) = true; //From your program, not w.r.t console.

If you would like to use --gtest_filter =*; /* =*, =xyz*... etc*/ // You need to use them in Console.

So, my requirement is to use them from the program not from the console.

Updated:-

Finally I got the answer for updating the same in from the program.

 ::testing::GTEST_FLAG(filter) = "*Counter*:*IsPrime*:*ListenersTest.DoesNotLeak*";//":-:*Counter*";
      InitGoogleTest(&argc, argv);
RUN_ALL_TEST();

So, Thanks for all the answers.

You people are great.

Answer 2

You could use advanced options to run Google tests.

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.

UPD:

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. 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

Answer 3

Summarising @Rasmi Ranjan Nayak and @nogard answers and adding another option:

On the console

You should use the flag --gtest_filter, like

--gtest_filter=Test_Cases1*

(You can also do this in Properties|Configuration Properties|Debugging|Command Arguments)

On the environment

You should set the variable GTEST_FILTER like

export GTEST_FILTER = "Test_Cases1*"

On the code

You should set a flag filter, like

::testing::GTEST_FLAG(filter) = "Test_Cases1*";

such that your main function becomes something like

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 Tests for more info on the syntax of the string you can use.
