I’m starting to wrap my head around PHPunit.

My questions is the following.

Whenever I use variables that do not change within my range of test methods I can initialize them within my setUp() method. Otherwise, if they do change, I should rather put them directly in my test methods.

Is my assumption more or less right?

• I put the username into the setUp() method because it will not change.
• The password comes directly into the functions because it needs to be changed in order to fail the test.

Example:

protected $  username;  protected function setUp() {     $  this->username = "Bob"; }  public function testUserCanLogInSuccessfully() {     $  password = "Right_Password";        // code }  public function testUserCanNotLogInSuccessfully() {     $  password = "Wrong_Password";     //code }
