Why are the assertX methods in PHPUnit_Framework_Assert static

[pjordaan]

Hi, one of my colleagues uses Phpstorm as IDE and every time he opens a test he gets a red line under any call to $this->assertEquals, $this->assertThat, because those methods are static and it should be self::assertEquals.

However in the entire phpunit codebase and in all documentation it's being used as a non static method. So why are these methods static in the first place? My colleague wants to change all calls to self::assertEquals which I find a waste of time to put effort into.
