Function TryReceive

testutil/chan.go:16–26

TryReceive will attempt to receive a value from the chan and return it. If the context expires before a value can be received, it will fail the test. If the channel is closed, the zero value of the channel type will be returned. Safety: Must only be called from the Go routine that created `t`.

	case <-ctx.Done():
		require.Fail(t, "TryReceive: context expired")
		var a A
		return a
	case a := <-c:
