  • Field Details

  • Constructor Details

    • FloatAssert

      protected FloatAssert(float actual)
      Creates a new FloatAssert.
      Parameters:
      actual - the actual value to verify.

      protected FloatAssert(Float actual)
      Creates a new FloatAssert.
      Parameters:

  • Method Details

    • as

      public FloatAssert as(String description)
      Sets the description of the actual value, to be used in as message of any AssertionError thrown when an assertion fails. This method should be called before any assertion method, otherwise any assertion failure will not show the provided description.

      For example: 

       assertThat(val).as("name").isEqualTo("Frodo");

      Specified by:
      as in class GenericAssert<Float>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • describedAs

      public FloatAssert describedAs(String description)
      Alias for GenericAssert.as(String), since "as" is a keyword in Groovy. This method should be called before any assertion method, otherwise any assertion failure will not show the provided description.

      For example: 

       assertThat(val).describedAs("name").isEqualTo("Frodo");

      Specified by:
      describedAs in class GenericAssert<Float>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • as

      public FloatAssert as(Description description)
      Sets the description of the actual value, to be used in as message of any AssertionError thrown when an assertion fails. This method should be called before any assertion method, otherwise any assertion failure will not show the provided description.

      For example: 

       assertThat(val).as(new BasicDescription("name")).isEqualTo("Frodo");

      Specified by:
      as in class GenericAssert<Float>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • describedAs

      public FloatAssert describedAs(Description description)
      Alias for GenericAssert.as(Description), since "as" is a keyword in Groovy. This method should be called before any assertion method, otherwise any assertion failure will not show the provided description.

      Specified by:
      describedAs in class GenericAssert<Float>
