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            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 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   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

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:

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

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  amp 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

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  amp argc  argv   RUN ALL TEST      So  Thanks for all the answers   You people are great
