NewFoo(t TestingT): Not documented

[guettli]

The generated code contains this method:

// NewFoo creates a new instance of Foo. It also registers a testing interface on the mock and a cleanup function to assert the mocks expectations.
// The first argument is typically a *testing.T value.
func NewFoo(t interface {
	mock.TestingT
	Cleanup(func())
}) *Foo {

I use testify mock for several months now, and just found that.

There seems to be no documentation for that:

At least not here: https://pkg.go.dev/github.com/stretchr/testify/mock

And not here: https://github.com/stretchr/testify

Is there a reason for that? I think that method is very handy, because it lets your test fail, instead of getting a random panic in another goroutine if you have an error in On(...).
