  • Method Details

    • as

      public BooleanAssert 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<Boolean>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • describedAs

      public BooleanAssert 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<Boolean>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • as

      public BooleanAssert 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<Boolean>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • describedAs

      public BooleanAssert 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.

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

      Specified by:
      describedAs in class GenericAssert<Boolean>

    • overridingErrorMessage

      public BooleanAssert overridingErrorMessage(String message)
      Replaces the default message displayed in case of a failure with the given one.

      For example, the following assertion: 

       assertThat("Hello").isEqualTo("Bye");
      will fail with the default message "expected:<'[Bye]'> but was:<'[Hello]'>."

      We can replace this message with our own: 

       assertThat("Hello").overridingErrorMessage("'Hello' should be equal to 'Bye'").isEqualTo("Bye");
      in this case, the assertion will fail showing the message "'Hello' should be equal to 'Bye'".

      Specified by:
      overridingErrorMessage in class GenericAssert<Boolean>
      Parameters:
      message - the given error message, which will replace the default one.
      Returns:
      this assertion.
