-    'Tests user authentication process'
-);
-// Configure test parameters
-$test
-    ->setVirtualUsers(1) // number of VUs (Virtual Users)
-//    ->setDuration('1s') // to run the test for 1 second
-    ->setHttpDebug(true); // to enable http debug mode remove it if you don't want to see the http debug
-
-// Create login scenario
-$loginScenario = $test->scenario('User Login')
-    ->autoHandleCookies(); // this will save cookies with all requests in this scenario
-
-
-$loginScenario->step('Register')
-    ->get('http://localhost:8001/register')

-    ->header('Accept', 'text/html')
-    ->validateStatus('status_code', 200);
-// Run the test 
-// This will start the test and block until it completes
-// pass true to run() to run the test with progress and real time results
-$result = $test->run(true);
-// OR $test->run(true);  to run the test with progress and real time results
-
-// Access test results
-echo "Success Rate: " . $result->getSuccessRate() . "%\n";
-echo "Average Response Time: " . $result->getAvgResponseTime() . "\n";
-```
