Assertionless Test
^^^^^
**Definition:**

* A test that does not contain at least one valid assertion is not a real test as it does only execute plain source-code, but never assert any data, state or functionality.
* Pretending to assert data and functionality, but does not


**Also Known As:**

* Lying Test, The Line Hitter, No Assertions


**Code Example:**

.. code-block:: Smalltalk

  // Smalltalk
  ICCreateCalendar>>TesttestCreatingSeveralCalendars
    self addCalendarWithName: ’new Calendar 1’.
    self addCalendarWithName: ’new Calendar 2’.
    self addCalendarWithName: ’new Calendar 3’.
    self addCalendarWithName: ’new Calendar 1’.
    self addCalendarWithName: ’new Calendar 2’.
    self addCalendarWithName: ’new Calendar 3’.
