Description:

PHPUnit 7.1.4 by Sebastian Bergmann and contributors.

PHP Fatal error:  Declaration of Laravel\BrowserKitTesting\Constraints\PageConstraint::fail($crawler, $description, ?SebastianBergmann\Comparator\ComparisonFailure $comparisonFailure = NULL) must be compatible with PHPUnit\Framework\Constraint\Constraint::fail($other, $description, ?SebastianBergmann\Comparator\ComparisonFailure $comparisonFailure = NULL): void in /Project/nginx/laravel-admin-select2/vendor/laravel/browser-kit-testing/src/Constraints/PageConstraint.php on line 124

In PageConstraint.php line 124:

Extra infomation:

I can see vendor/laravel/browser-kit-testing/src/Constraints/PageConstraint.php's fail method declaring

    /**
     * Throw an exception for the given comparison and test description.
     *
     * @param  \Symfony\Component\DomCrawler\Crawler|string  $crawler
     * @param  string  $description
     * @param  \SebastianBergmann\Comparator\ComparisonFailure|null  $comparisonFailure
     * @return void
     *
     * @throws \PHPUnit\Framework\ExpectationFailedException
     */
    protected function fail($crawler, $description, ComparisonFailure $comparisonFailure = null)
    {

and vendor/phpunit/phpunit/src/Framework/Constraint/Constraint.php's declaring

    /**
     * Throws an exception for the given compared value and test description
     *
     * @param mixed             $other             Evaluated value or object.
     * @param string            $description       Additional information about the test
     * @param ComparisonFailure $comparisonFailure
     *
     * @throws ExpectationFailedException
     */
    protected function fail($other, $description, ComparisonFailure $comparisonFailure = null)
    {

They have different parameter declares. Please check the compatible with phpunit which version i pasted.

Hey there,

Necro-commenting on this issue, as it's the first result in google when searching for the error string - which is still almost the same, 4 years later!

As discovered in this related issue, the actual problem is caused by you running a locally installed phar phpunit, instead of the one in vendor/bin/phpunit. Fix your PATH, remove the /usr/bin/phpunit, or whatever you want so you use the correct one.

FYI, i can repro this issue in Composer-installed PHPUnit too, pinning 9.5.19 as version, while it's fine with 9.5.20.
