Can PHPUnit be used to test entire program flows or just individual methods?

PHPUnit can be used to test both individual methods and entire program flows. To test entire program flows, you can use PHPUnit to create test cases that simulate the execution of multiple methods in a specific order to ensure that the program behaves as expected. This can be achieved by setting up the necessary test data, calling the methods in the desired sequence, and asserting the expected outcomes at each step. 

// Example of testing an entire program flow with PHPUnit

use PHPUnit\Framework\TestCase;

class ProgramFlowTest extends TestCase
{
    public function testEntireProgramFlow()
    {
        // Set up test data
        $data = [
            'input' => 5,
            'expected_output' => 10
        ];

        // Call methods in the desired sequence
        $result = $this->method1($data['input']);
        $result = $this->method2($result);

        // Assert the expected outcome
        $this->assertEquals($data['expected_output'], $result);
    }

    public function method1($input)
    {
        return $input * 2;
    }

    public function method2($input)
    {
        return $input + 5;
    }
}
