Bug: Model doesn't reset errors in FeatureTestCase

[lefuentes]

Describe the bug
When I test with FeatureTestCase class the errors of models don't reset and I receive the last error.
Example:
Test PUT Method with bad validation. It return that I expect. But in the next test if I Test Put Method with success validation I still receive the last errors.
Example

CodeIgniter 4 version
latest.

Context

• OS: [Linux]
• PHP version [7.3]

Are your tests using model() or ModelFactory to load your models? If so you are probably getting shared instances of them. You can use ModelFactory::reset() in your test setUp() to make sure shares instances are cleared. This might not be a bad idea to add to the default resets.

I don't use ModelFactory. I will try with that. But I think it doesn't a clear solution.
I have another bug when I use FeatureTestCase. The filters definied in the routes don't reset when first I test an route with filter and then I test an route without filters.

CodeIgniter4/system/CodeIgniter.php

Line 409 in 8c90aa0

$routeFilter = $this->tryToRouteIt($routes);

It's beacuse the variable filterInfo has the before value

CodeIgniter4/system/Router/Router.php

Line 182 in 8c90aa0

$this->filterInfo = $this->collection->getFilterForRoute($this->matchedRoute[0]);

If it's necessary I will create another issue.

The Filters issue sounds like this (#3085) resolves July 7. Are you using the latest version of the code?

[lefuentes]

I tried this solution but it doesn't work. it's apply after of function tryToRouteIt.
Tomorrow I will upload an example complete about this bug.

[MGatner]

Okay, please open a new issue for the filters example, and this can track the validation issue. My guess is that you will need to reset Validation between tests - something we should probably be doing in the core.

It's an example when models doesn't reset de errors.

If it's necessary I upload more files.

This is actually expected. CIUnitTestCase does not reset Services by default:

	/**
	 * Methods to run during setUp.
	 *
	 * @var array of methods
	 */
	protected $setUpMethods = [
		'resetFactories',
		'mockCache',
		'mockEmail',
		'mockSession',
	];

If you desire this behavior there is already a resetServices method you can add to that list, or call during your test case's setUp().
