Question about running single test in the new UT framework

I used to go test -check.f "XXX" where XXX is the name of the testing function, like TestConfig to run a specific unit test, this is very handy for fixing single test case that is failing.

However in the new test framework, it does not work.

I indeeded searched about such feature in testifiy, and got -testify.m, however it does not really work (at least on my platform)

see

go test -run TestConfig -testify.m TestConfig                                                                                                                                                                                                          1 ↵

So I would like to ask the community how do you do single case testing in the new testify framework?

A lot of thanks for helping me out (and I am sure there are many people wondering about this feature as well)

I think testify supports:
-test.run XXX

Thanks! it works! :smiley:
