The difference in the error messages you're seeing is due to Laravel's exception handling. By default, Laravel's testing framework catches exceptions and converts them into HTTP responses with status codes. When an exception is thrown, Laravel will return a 500 status code, which is a generic server error response.
The assertOk() method is an assertion that checks if the response status code is 200. When your test receives a 500 status code, it means that an exception was thrown and not handled within your application, causing the test to fail with a simple status code mismatch message.
The $this->withoutExceptionHandling(); method disables Laravel's exception handling within the test, allowing exceptions to bubble up to the test framework. When you use this method, you get the actual exception message and stack trace, which can help you debug the issue more easily.
To see the detailed error message without disabling exception handling, you can check the Laravel log files, which by default are located in storage/logs/. Alternatively, you can temporarily use $this->withoutExceptionHandling(); in your test to get the detailed error message and stack trace directly in your test output.
Here's how you might modify your test to use $this->withoutExceptionHandling();:
/** @test */
public function it_shows_course_details()
{
$this->withoutExceptionHandling(); // Temporarily disable exception handling
$course = Course::factory()->create();
// Your test code here...
$response = $this->get(route('course-details', $course));
$response->assertOk()
->assertSeeText([
$course->title,
$course->description,
// ... other text to assert
]);
// Remember to remove or comment out the withoutExceptionHandling() call
// once you've fixed the issue causing the exception.
}
Remember to remove or comment out the withoutExceptionHandling() call once you've fixed the issue causing the exception, as you'll want exceptions to be handled normally in most cases.
