Dusk not showing green status on correct test

Hi, My dusk test was alright before. It used to show me green status in my terminal and red whenever test fails. But now on correct test it showing this message instead of green status. My test is correct. Need your help. Thanks

example

public function testExample()
    {
        $this->browse(function (Browser $browser) {
            $browser->loginAs(User::find(1))
                ->visit('/forms')
                ->assertSee('Forms');
                ;
        });
    }

error in terminal
