ARCHIVED, NO LONGER NEEDED.
---------------------------

[](#archived-no-longer-needed)

This package is no longer needed, since PHPUnit now destructs the TestCase instances during the run.

- Initial PR by Sebastian 🔥 , [PR 5861](https://github.com/sebastianbergmann/phpunit/pull/5861), released in PHPUnit [10.5.21 / 11.2.2](https://github.com/sebastianbergmann/phpunit/releases/tag/10.5.21).
- Final PR by me 😎 , [PR 5875](https://github.com/sebastianbergmann/phpunit/pull/5875#issuecomment-2179933860), released in PHPUnit [10.5.23 / 11.2.4](https://github.com/sebastianbergmann/phpunit/releases/tag/10.5.23)

---

PHPUnit keeps all Test instance in memory for the whole run. This causes used memory to continuously increase, unless you clean up all your properties during a tearDown().

There's No Doubt you'll eventually forget this tedious task.

Installation
------------

[](#installation)

```
composer require --dev talkinnl/dont-leak
```

Usage
-----

[](#usage)

In your Test classes, add this as a **very last line** of your tearDown().

Maybe you'd like to always use a common parent class so you'll never forget.

```
    protected function tearDown(): void
    {
        // Start with some of your cleanups which are still needed.
        // Maybe removing files made during the test etc

        // Always call your parents; they might get worried. :)
        parent::tearDown();

        // Unset any properties, prevent memory leaks.
        DontLeak::freeOwnProperties($this);
    }
```

What does it do?
----------------

[](#what-does-it-do)

`DontLeak::freeOwnProperites($object)` unsets all properties reachable in your own scope of given $object, and all private properties of parent objects.

Properties defined by PHPUnit WON'T be touched.

What's next
-----------

[](#whats-next)

I'd really like it if this package would be become obsolete thanks to PHPUnit changing the behaviour.

Please read, and maybe vote --> [sebastianbergmann/phpunit#4705](https://github.com/sebastianbergmann/phpunit/issues/4705)

Many suggestions of a tearDown which uses reflection to clean up exist scattered across Stack Overflow, Reddit, Github, etc.

The implementation was heavily inspired by  , which unsets instead of assigning null, and also clears private properties of safe parents.
