This test suite provides comprehensive functional coverage of:

  • All Time constructors
  • Parsing: valueOf and of
  • Reference creation, lookup, and simple offset transformations
  • Arithmetic operations: subtract(Time), add(Duration), subtract(Duration)
  • Display-unit propagation rules
  • Inherited operations from AbsoluteQuantity: comparisons, zero checks, interpolate, sum, mean, min, max

    Modifier and Type
    Method
    Description
    (package private) final void
    setup()
    Set Locale.US for consistent number parsing and formatting.
    (package private) void
    testArithmetic()
    Test subtract(Time) → Duration, add(Duration) → Time, subtract(Duration) → Time, and check display-unit propagation from the absolute quantity.
    (package private) void
    testComparisonOperators()
    Test lt, le, gt, ge, eq, ne, compareTo.
    (package private) void
    testConstructors()
    Test all Time constructors: (value, unit, reference), (value, abbreviation, reference), and (Duration, reference), as well as ofSi(..., reference).
    (package private) void
    testParsing()
    Test parsing of textual values via valueOf(text, reference) and of(value, unitString, reference), including error paths.
    (package private) void
    testReferenceBehavior()
    Test Reference.get for built-ins and simple add/get with offset.
    (package private) void
    testStaticOperations()
    Test the static operations inherited from AbsoluteQuantity: interpolate, min, max, sum, and mean, using the same reference.
    (package private) void
    testZeroComparisonsAndNumericConversions()
    Test lt0, le0, gt0, ge0, eq0, ne0 and numeric Number conversions.

    • setup

      @BeforeEach final void setup()
      Set Locale.US for consistent number parsing and formatting.

    • testConstructors

      @Test void testConstructors()
      Test all Time constructors: (value, unit, reference), (value, abbreviation, reference), and (Duration, reference), as well as ofSi(..., reference).

    • testParsing

      @Test void testParsing()
      Test parsing of textual values via valueOf(text, reference) and of(value, unitString, reference), including error paths.

    • testReferenceBehavior

      @Test void testReferenceBehavior()
      Test Reference.get for built-ins and simple add/get with offset. Also verify relativeTo(...) for a single-level offset, and that unrelated built-ins (with no defined path) cannot be transformed.

    • testArithmetic

      @Test void testArithmetic()
      Test subtract(Time) → Duration, add(Duration) → Time, subtract(Duration) → Time, and check display-unit propagation from the absolute quantity.

    • testComparisonOperators

      @Test void testComparisonOperators()
      Test lt, le, gt, ge, eq, ne, compareTo. Mismatched references should throw.

    • testZeroComparisonsAndNumericConversions

      @Test void testZeroComparisonsAndNumericConversions()
      Test lt0, le0, gt0, ge0, eq0, ne0 and numeric Number conversions.

    • testStaticOperations

      @Test void testStaticOperations()
      Test the static operations inherited from AbsoluteQuantity: interpolate, min, max, sum, and mean, using the same reference. Mixed references should throw.
