Question

How to test specific validation errors in php unit thrown in validation error ? with below code we could check session has errors, but not the exact error

Answer 1

Got the answer

    $errors = session('errors');
    $this->assertSessionHasErrors();
    $this->assertEquals($errors->get('name')[0],"Your error message for validation");

$errors is MessageBag object which stored in laravel session when validation error thrown using $errors->get('name') you could see all the validation errors as an array
