Rule php_unit_namespaced

PHPUnit classes MUST be used in namespaced version, e.g. \PHPUnit\Framework\TestCase instead of \PHPUnit_Framework_TestCase.

Description

PHPUnit v6 has finally fully switched to namespaces. You could start preparing the upgrade by switching from non-namespaced TestCase to namespaced one. Forward compatibility layer (\PHPUnit\Framework\TestCase class) was backported to PHPUnit v4.8.35 and PHPUnit v5.4.0. Extended forward compatibility layer (PHPUnit\Framework\Assert, PHPUnit\Framework\BaseTestListener, PHPUnit\Framework\TestListener classes) was introduced in v5.7.0.

Warning

Using this rule is risky

Risky when PHPUnit classes are overridden or not accessible, or when project has PHPUnit incompatibilities.
