  • Constructor Details

    • ScaleTest

      public ScaleTest()

  • Method Details

    • testScale

      @Test public void testScale()
      Test the correct implementation of scales.

    • testIdentityAndLinearRoundTrip

      @Test public void testIdentityAndLinearRoundTrip()
      Extra round-trip checks for IdentityScale and LinearScale.

    • testGradeScaleAdditional

      @Test public void testGradeScaleAdditional()
      GradeScale: more trigonometric sanity tests and round-trips.

    • testEqualsHashCodeContracts

      @Test public void testEqualsHashCodeContracts()
      equals/hashCode: symmetry, transitivity, and inequality with close-but-different parameters.

    • testRenderingNoMutation

      @Test public void testRenderingNoMutation()
      Rendering should not mutate internal state (smoke check for all scales).

    • testSpecialDoubleBehavior

      @Test public void testSpecialDoubleBehavior()
      Extremes and special doubles — adapt depending on the intended contract. If NaN/Infinite should be rejected, replace with assertThrows.

    • testConstructorValidation

      @Test public void testConstructorValidation()
      Test constructors against illegal arguments.

    • testLinearScaleNumDenConstructorValidation

      @Test public void testLinearScaleNumDenConstructorValidation()
      Constructor validation for LinearScale(numerator, denominator).

    • testLinearScaleNumDenCorrectness

      @Test public void testLinearScaleNumDenCorrectness()
      Correctness for LinearScale(numerator, denominator) using the km/h ↔ m/s example. A value in km/h multiplied by (1000/3600) yields m/s.

    • testIsBaseScale

      @Test public void testIsBaseScale()
      isBaseScale() checks across scale classes.
