+### Exception Handling
+
+Sometimes you may want to test that your application is throwing a specific exception. To ensure that the exception does not get caught by Laravel's exception handler and returned as an HTTP response, you may invoke the `withoutExceptionHandling` method before making your request:
+
+    $response = $this->withoutExceptionHandling()->get('/');
+
+In addition, if you would like to ensure that your application is not utilizing features that have been deprecated by the PHP language or the libraries your application is using, you may invoke the `withoutDeprecationHandling` method before making your request. When deprecation handling is disabled, deprecation warnings will be converted to exceptions, thus causing your test to fail:
+
+    $response = $this->withoutDeprecationHandling()->get('/');
