PHPUnit 8 Shift

The PHPUnit 8 Shift reviews your tests for any backward incompatible changes and automates the upgrade process to PHPUnit 8.

Requirements

• Running PHP 7.2 or higher.
• Previously running PHPUnit 6 or higher.
• Test classes within the tests folder.

Automated Changes

• Adding return types to core TestCase methods.
• Updating phpunit/phpunit composer dependency to ^8.0.
• Converting uses of the deprecated assertInternalType to its type specific equivalent.
• Detecting uses of the deprecated assertContains and converting to the string assertion when appropriate.
• Modernizing PHP syntax, such as the short array syntax.

Manual Changes

While the PHPUnit 8 Shift addresses backward incompatible changes, there are also deprecations you may wish to review manually.
