当方法phpunit中没有参数时，assertFalse应该传递

Question

My Test includes the wp_verify_nonce and implemented that in OOP environment. Now the problem is: If verifyNonce() has no arguemnts passed, then i want to expect return false due to the function:

verifyNonce():

     public function verifyNonce( $nonce ) {

          if( ! function_exists( 'wp_verify_nonce') || empty( $nonce ) || !is_string( $nonce ) )  return false; 

          return wp_verify_nonce( $nonce, $this->action );

     }

If $nonce is empty then it should return false since i passed this the if condition!

Now here i'm expecting that when there is no arguements passed, then it should return false:

testVerifyNonce():

public function testVerifyNonce() {

      $action        = 'my_action';
      $nonce         = '4832552f';

      $myWPNonce     = new test\MY_WP_Nonces( $action );

      \WP_Mock::userFunction( 'wp_verify_nonce', array( 

           'times'             =>   3,
           'return_in_order'   =>   array(false, 1, 2)

      ) );

      $this->assertFalse( $myWPNonce->verifyNonce() );

      $this->assertEquals( 1, $myWPNonce->verifyNonce( $nonce ) );

      $this->assertEquals( 2, $myWPNonce->verifyNonce( $nonce ) );

 }

Here's the output of my bash console:

PHPUnit 5.1.7 by Sebastian Bergmann and contributors.

PHPUnit tests your returning value of $myWPNonce->verifyNonce(). Before this can be accomplished you must pass the parameter, as it is defined in the method as mandatory parameter.

PHPUnit does not test forgotten/missing parameters. PHP itself validates this.

So pass something what should return false there as result.
