 - If you need to verify a feature is working, write or update a Unit / Feature test.
 
 ### Pest Tests
-- All tests must be written using Pest. Use `php artisan make:test --pest <name>`.
+- All tests must be written using Pest. Create a php file named PascalCaseTest, where "Test" is a mandatory suffix. For example, "CustomFeedTest.php".
 - You must not remove any tests or test files from the tests directory without approval. These are not temporary or helper files - these are core to the application.
 - Tests should test all of the happy paths, failure paths, and weird paths.
 - Tests live in the `tests/Feature` and `tests/Unit` directories.

 - To filter on a particular test name: `php vendor/bin/pest --filter=testName` (recommended after making a change to a related file).
 - When the tests relating to your changes are passing, ask the user if they would like to run the entire test suite to ensure everything is still passing.
 
-### Pest Assertions
-- When asserting status codes on a response, use the specific method like `assertForbidden` and `assertNotFound` instead of using `assertStatus(403)` or similar, e.g.:
-<code-snippet name="Pest Example Asserting postJson Response" lang="php">
-it('returns all', function () {
-    $response = $this->postJson('/api/docs', []);
-
-    $response->assertSuccessful();
-});
-</code-snippet>

 ### Mocking
 - Mocking can be very helpful when appropriate.
 - When mocking, you can use the `Pest\Laravel\mock` Pest function, but always import it via `use function Pest\Laravel\mock;` before using it. Alternatively, you can use `$this->mock()` if existing tests do.
 - You can also create partial mocks using the same import or self method.
 
 ### Datasets
 - Use datasets in Pest to simplify tests which have a lot of duplicated data. This is often the case when testing validation rules, so consider going with this solution when writing tests for validation rules.
+- - Check whether the dataset with the required data set exists in the files in the “datasets” folder. If the required set exists, use its name; otherwise, create a new one.
