Specify namespace/class in VS2019 Test Explorer while using CTest/CMake

Question

I'm using CMake + VS2019. In my test definition I have something like:

add_test(NAME "common/base64" COMMAND my_unit_test "common/base64")

VS2019 displays this like:

In project I have hundreds of tests and it is very inconvenient to search through unclear randomly generated names, expanding each items. So my questions:

• How can I specify recognizable test name (instead of EBF.Tests.52488745200006951440) ?
• How to specify namespace / class?

Also I can see Vs2019 Test Explorer can group by "Traits" - may be I can specify it over this feature?

Answer 1

It seems that the "EBF.Tests" prefix is the "project name".

You can disable the test prefix or set a new one by altering the TEST_PREFIX setting in your test autodiscovery method or the test naming itself.

For CTest, by altering the test naming:

# use [namespace].[class].[testname] naming 
add_test("lib.namespace.Tests.SomeTest" test_exe)

For Catch2, by altering the test name prefixing by changing TEST_PREFIX in the auto-discovery method:

catch_discover_tests(
    TagTestsTarget
    TEST_SPEC "[tag]"                   # select tests by tag name
    TEST_PREFIX "lib.namespace.Tests."  # last dot required !
)
