I see TestMain in other PRs, can it be extracted into a function and reused?

[maxshuang]

It is the package level function. Before all other test-case in any *_test.go, TestMain will be called firstly to do some initialization work.

I don't think it can be wrapped.

[overvenus]

Can we extract following code?

package somepkg

func SetupGoLeak(m *testing.M) {
	opts := []goleak.Option{
		goleak.IgnoreTopFunction("go.etcd.io/etcd/pkg/logutil.(*MergeLogger).outputLoop"),
		goleak.IgnoreTopFunction("go.opencensus.io/stats/view.(*worker).start"),
	}

	goleak.VerifyTestMain(m, opts...)
}

// -------

package otherpkg

import somepkg

func TestMain(m *testing.M) {
    somepkg.SetupGoLeak(m)
}

[maxshuang]

But i am not sure if SetupGoLeak is so common that need to be wrapped. Some pkgs will add other stack functions.

I will check later.
