      protected AbstractOptionalDoubleAssert(OptionalDouble actual, Class<?> selfType)

  • Method Details

    • isPresent

      public SELF isPresent()
      Verifies that there is a value present in the actual OptionalDouble.

      Assertion will pass : 

       assertThat(OptionalDouble.of(10.0)).isPresent();

      Assertion will fail : 

       assertThat(OptionalDouble.empty()).isPresent();
      Returns:
      this assertion object.
      Throws:
      AssertionError - if actual value is empty.
      AssertionError - if actual is null.

    • isNotPresent

      public SELF isNotPresent()
      Verifies that the actual Optional is empty (alias of isEmpty()).

      Assertion will pass : 

       assertThat(OptionalDouble.empty()).isNotPresent();
      Assertion will fail : 
       assertThat(OptionalDouble.of(10.0)).isNotPresent();
      Returns:
      this assertion object.

    • isEmpty

      public SELF isEmpty()
      Verifies that the actual OptionalDouble is empty.

      Assertion will pass : 

       assertThat(OptionalDouble.empty()).isEmpty();

      Assertion will fail : 

       assertThat(OptionalDouble.of(10.0)).isEmpty();
      Returns:
      this assertion object.
      Throws:
      AssertionError - if actual value is present.
      AssertionError - if actual is null.

    • isNotEmpty

      public SELF isNotEmpty()
      Verifies that there is a value present in the actual OptionalDouble, it's an alias of isPresent().

      Assertion will pass : 

       assertThat(OptionalDouble.of(10.0)).isNotEmpty();

      Assertion will fail : 

       assertThat(OptionalDouble.empty()).isNotEmpty();
      Returns:
      this assertion object.
      Throws:
      AssertionError - if actual value is empty.
      AssertionError - if actual is null.

    • hasValue

      public SELF hasValue(double expectedValue)
      Verifies that the actual OptionalDouble has the value in argument.

      Assertion will pass : 

       assertThat(OptionalDouble.of(8.0)).hasValue(8.0);
 assertThat(OptionalDouble.of(8.0)).hasValue(Double.valueOf(8.0));
 assertThat(OptionalDouble.of(Double.NaN)).hasValue(Double.NaN);

      Assertion will fail : 

       assertThat(OptionalDouble.empty()).hasValue(8.0);
 assertThat(OptionalDouble.of(7)).hasValue(8.0);
      Parameters:
      expectedValue - the expected value inside the OptionalDouble.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if actual value is empty.
      AssertionError - if actual is null.
      AssertionError - if actual has not the value as expected.

    • hasValueCloseTo

      public SELF hasValueCloseTo(Double expectedValue, Offset<Double> offset)
      Verifies that the actual OptionalDouble has the value close to the argument.

      Assertion will pass : 

       assertThat(OptionalDouble.of(8)).hasValueCloseTo(8.0, within(0d));
 assertThat(OptionalDouble.of(8)).hasValueCloseTo(8.0, within(1d));
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(8.0, within(1d));

      Assertion will fail : 

       assertThat(OptionalDouble.empty()).hasValueCloseTo(8.0, within(1d));
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(1.0, within(1d));
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(1.0, null);
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(1.0, within(-1d));
      Parameters:
      expectedValue - the expected value inside the OptionalDouble.
      offset - the given positive offset.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if actual value is empty.
      AssertionError - if actual is null.
      AssertionError - if actual has not the value as expected.
      NullPointerException - if offset is null
      IllegalArgumentException - if offset is not positive.

    • hasValueCloseTo

      public SELF hasValueCloseTo(Double expectedValue, Percentage percentage)
      Verifies that the actual OptionalDouble has a value close to the expected value, within the given percentage.
      If the difference is equal to the percentage value, the assertion is considered valid. 
      // The assertion will pass:
 assertThat(OptionalDouble.of(11)).hasValueCloseTo(10.0, withinPercentage(20));

 // If the difference is exactly equals to the computed offset (1.0), the assertion will pass:
 assertThat(OptionalDouble.of(11)).hasValueCloseTo(10.0, withinPercentage(10));

 // The assertions will fail:
 assertThat(OptionalDouble.of(11)).hasValueCloseTo(10.0, withinPercentage(5));
 assertThat(OptionalDouble.empty()).hasValueCloseTo(10.0, withinPercentage(5));
      Parameters:
      expectedValue - the expected value inside the OptionalDouble
      percentage - the given positive percentage
      Returns:
      the assertion object
      Throws:
      AssertionError - if actual value is empty
      AssertionError - if actual is null
      AssertionError - if the actual value is not close to the given one
