public class DoubleArrayAssert extends ArrayAssert<double[]>
Understands assertion methods for double arrays. To create a new instance of this class use the method Assertions.assertThat(double[]).

  • Constructor Details

    • DoubleArrayAssert

      protected DoubleArrayAssert(double... actual)
      Creates a new DoubleArrayAssert.
      Parameters:
      actual - the target to verify.

  • Method Details

    • as

      public DoubleArrayAssert 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 GroupAssert<double[]>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • describedAs

      public DoubleArrayAssert 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 GroupAssert<double[]>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • as

      public DoubleArrayAssert 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 GroupAssert<double[]>
      Parameters:
      description - the description of the actual value.
      Returns:
      this assertion object.

    • describedAs

      public DoubleArrayAssert 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.

      For example: 

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

      Specified by:
      describedAs in class GroupAssert<double[]>
      Parameters:

    • overridingErrorMessage

      public DoubleArrayAssert 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 GroupAssert<double[]>
      Parameters:
      message - the given error message, which will replace the default one.
      Returns:
      this assertion.
