Multiple tests with a similar name get executed when running go test with -testify.m option

[hcbt]

When running my test suite I have noticed that it gets stuck on some tests even if they work fine when I run them independently, each test in suite is independent so order in which you run them does not matter. I have investigated further and noticed that running go test -testify.m TestName runs multiple tests that have a similar name.

For example running:
go test -v mongodb_test.go -testify.m TestMongoDBGetAccount

Gives a following output:

=== RUN   TestGuestAccessTestSuite
=== RUN   TestGuestAccessTestSuite/TestMongoDBGetAccount
time="2021-07-30T14:49:17+03:00" level=info
=== RUN   TestGuestAccessTestSuite/TestMongoDBGetAccountByPortalIDAndUsername
time="2021-07-30T14:49:17+03:00" level=info
=== RUN   TestGuestAccessTestSuite/TestMongoDBGetAccountStatistics
time="2021-07-30T14:49:17+03:00" level=info
=== RUN   TestGuestAccessTestSuite/TestMongoDBGetAccountsByPortal
time="2021-07-30T14:49:17+03:00" level=info
--- PASS: TestGuestAccessTestSuite (0.46s)
    --- PASS: TestGuestAccessTestSuite/TestMongoDBGetAccount (0.05s)
    --- PASS: TestGuestAccessTestSuite/TestMongoDBGetAccountByPortalIDAndUsername (0.10s)
    --- PASS: TestGuestAccessTestSuite/TestMongoDBGetAccountStatistics (0.10s)
    --- PASS: TestGuestAccessTestSuite/TestMongoDBGetAccountsByPortal (0.21s)
PASS
ok  	command-line-arguments	0.475s

Is this an intended behaviour or am I doing something wrong?

Follow the doc, testify.m means regular expression to select tests of the testify suite to run, the behavior is expected. You need to use go test -v mongodb_test.go -testify.m TestMongoDBGetAccount$ to match.

test % go test -v main_test.go -testify.m=TestMongoDBGetAccount
=== RUN   TestGuestAccessTestSuite
=== RUN   TestGuestAccessTestSuite/TestMongoDBGetAccount
=== RUN   TestGuestAccessTestSuite/TestMongoDBGetAccountByPortalIDAndUsername
