Test Result

Failed asserting that exception of type "Exception" is thrown.

I am wondering how to pass the test Any help

In a bit of hurry now. You cannot set the expected exception.  Please refer this for a workaround.

public function testDivByZero()
{
    try {
        // Fyi you don't need to do an assert test here, as we are only testing the exception, so just make the call
        $result = $this->object->div(1,0);
    } catch (Exception $e) {
        if ('Exception' === get_class($e)) {
            throw new Test_Exception($e->getMessage(), $e->getCode());
        }
    }
 }

 // Test_Exception.php
 class Test_Exception extends Exception
 {
     public function __construct($message = null, $code = 0, Exception $previous = null)
     {
         parent::__construct($message, $code, $previous);
     }
 }

Thank you for your responses . But I want the test to be written like this, don't reconstruct it.

/* @test*/ 
public function NotExistingUserName()
	    {
	        $Getuser 	= new Mynamespace\Getuser("Ade");
	        $this->setExpectedException('Exception');
	       	$NameUser 		= $Getuser->getFullName('Owolabi');
	    }

Let say this how the test is written what do I need to do to make it pass. on working.php

/* @test*/
public function NotExistingUserName()
          {
              $Getuser       = new Mynamespace\Getuser("Ade");
              $this->setExpectedException(ExpectedException::class);
                   $NameUser             = $Getuser->getFullName('Owolabi');
          }
