[FR]: Test names output by googletest are too long

Does the feature exist in the most recent commit?

No.

Why do we need this feature?

I have a test suite called AutoTest with a parameterized test called Compile. The parameter is a custom type. I provide a function as the 4th argument to INSTANTIATE_TEST_SUITE_P that generates test names based on the parameter. When googletest lists tests names, it prints stuff like A/AutoTest.Compile/firstpass_preproc_set # GetParam() = 64-byte object <10-61 1E-61 40-7B 00-00 2F-00 00-00 00-00 00-00 2F-00 00-00 00-00 00-00 BE-BE BE-BE BE-BE BE-BE 40-82 23-61 40-7C 00-00 01-00 00-00 00-00 00-00 00-00 00-40 00-00 00-00 00-00 00-00 00-00 00-00>. Everything following the string that my function generates ("firstpass_preproc_set" in this case) is basically undesired spam. It's just noise that takes up precious screen real estate.

Describe the proposal.

I suppose the intent behind " # GetParam() = . . ." was to print the parameter as a way to clarify which value is being used as the parameter to a TEST_P, but I (like most parameterized test users, I'd think?) already use the 4th argument to INSTANTIATE_TEST_SUITE_P to provide all the information I need to know about the value. There is nothing more of value to be printed aside from the name I'm already giving it.

I found a documented way to provide a custom string formatter for my parameter type, which I can make return an empty string, but googletest still outputs the undesired " # GetParam() = ".

I modified googletest to stop it from doing this (in UnitTestImpl::ListTestsMatchingFilter) but would love to know if there is an official way to get test names listed without the "# GetParam()" stuff. If there is no official way, please add one.

Is the feature specific to an operating system, compiler, or build system version?

No.

Start at UnitTestImpl::ListTestsMatchingFilter, where the issue reports that the parameter text is appended to listed test names, and review the documented custom string formatter behavior. Determine how an official opt-out could fit the existing parameterized-test naming flow. Done means users can list tests using their generated names without the unwanted "# GetParam() =" suffix.
