How to test session and cookie data in PHPUnit?

@jasen 

To test session and cookie data in PHPUnit, you can use the following steps:

1. Install PHPUnit by running the following command:

1

composer require --dev phpunit/phpunit

1. Create a new test class that extends the PHPUnitFrameworkTestCase class. For example, create a file named SessionAndCookieTest.php with the following content:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

assertEquals('bar', $_SESSION['foo']);
    }

    public function testCookieData()
    {
        // Set and check cookie data
        setcookie('foo', 'bar', time() + 3600);
        $this->assertEquals('bar', $_COOKIE['foo']);
    }
}

1. Run the test using PHPUnit by executing the following command in the terminal:

1

vendor/bin/phpunit SessionAndCookieTest.php

PHPUnit will execute the test methods and provide the test results. If the assertEquals assertions pass, it means that the session and cookie data are working as expected.

Note: Make sure that you have the session and cookie handling enabled in your PHPUnit configuration file if required.
