#Exit (or die)

class foo
{
    public function bar ()
    {
        // ...
  
        exit(); 
    }
}

##Why is this a testing issue?

Pretty self-explanatory. If a method calls exit() or die() the execution stops immediately and the test doesn't run.

##Possible refactorings

####Don't use it

Use conditionals instead. If the conditions are not met, nothing happens and the script ends normally.

####Use exceptions instead

 throw new Exception ('Fatal error');

####If you really need to use exit() (ie: for a CLI script return value)

Write a wrapper method.

class foo
{
    public function bar ()
    {
        // ...
  
        $this->exitApp();
    }
  
    public function exitApp ($code);
    {
        // this method will be untestable, but
        // it can be mocked to test other methods
        // that depend on it

        exit ($code);
    }
}

While this sounds silly, it allows you to unit test ->bar() with a fake ->exitApp() method, without breaking the execution.
