How can I get coverage in the Suite package

[mkuznetsov2]

I used this part of the testify https://github.com/stretchr/testify?tab=readme-ov-file#suite-package And my test look like

func TestRun(t *testing.T) {
    ctx := context.Background()
    connection := src.PrepareDB(t, ctx)

    suite.Run(t, &Suite1{DBConnection: connection})
    suite.Run(t, &Suite2{DBConnection: connection})
}
type Suite1 struct {
    suite.Suite
    DBConnection *pgsql.TxManager
}

func (s *Suite1) SetupTest() {}

func (s *Suite1) TearDownSuite() {}

func (s *Suite1) TestSuite1() {
    // DO SOMTHING HELPFUL

    assert.Equal(s.T(), ...)
}

And I try to fetch coverage tests by command go test -v -coverprofile=coverage.txt -covermode count But I have just empty coverage.txt and message coverage: [no statements] Output run of tests

--- PASS: TestRun (4.77s)
    --- PASS: TestRun/TestSuite1 (0.03s)
    --- PASS: TestRun/TestSuite2 (0.05s)
PASS
coverage: [no statements]
ok      myProject/tests 5.809s

Can you explain, how get coverage tests?

I can't reproduce this behaviour, using go test -v -coverprofile=coverage.txt -covermode count I get coverage information in coverage.txt.

What does go env show for you and what version of testify are you using?

But in CI/CD it doesn't work too. I use GitlabCI and image golang:1.21-bookworm

What testify version are you using?

Using (mostly) your code example with go 1.21.6 on darwin/arm64 I get coverage:

% go version
go version go1.21.6 darwin/arm64
% go test -v -coverprofile=coverage.txt -covermode count
=== RUN   TestRun
=== RUN   TestRun/TestSuite1
--- PASS: TestRun (0.00s)
    --- PASS: TestRun/TestSuite1 (0.00s)
PASS
coverage: 100.0% of statements
ok      github.com/brackendawson/kata   0.593s
% cat coverage.txt
mode: count
github.com/brackendawson/kata/kata.go:3.21,5.2 1 1

Does your code actually have any statements?

github.com/stretchr/testify v1.8.4 (last version)

>go version
go version go1.21.6 darwin/arm64

>go test -v -coverprofile=coverage.txt -covermode count
=== RUN   TestRun
=== RUN   TestRun/TestISuite1
--- PASS: TestRun (0.05s)
    --- PASS: TestRun/TestISuite1 (0.00s)
PASS
coverage: [no statements]
ok      mytests/tests   0.586s

>cat coverage.txt
mode: count

Does your code actually have any statements?

Yes, I have code which work with DB. But I tried to write "test code" and find the problem. I got the same empty coverage.

Can you share a compilable recreate?
