      info - contains information about the assertion.
      actual - the actual value.
      Throws:
      AssertionError - if the actual value is null.
      AssertionError - if the actual value is not equal to zero.

    • assertIsNotZero

      public void assertIsNotZero(AssertionInfo info, NUMBER actual)
      Asserts that the actual value is not equal to zero.
      It does not rely on the custom comparisonStrategy (if one is set).
      Parameters:
      info - contains information about the assertion.
      actual - the actual value.
      Throws:
      AssertionError - if the actual value is null.

    • assertIsNegative

      public void assertIsNegative(AssertionInfo info, NUMBER actual)
      Asserts that the actual value is negative.
      Parameters:
