'''!- ConstraintFixture -!'''!- is a variation of -!'''!- CalculateFixture -!'''!- (see -![[!-CalculateFixture-!][<UserGuide.FixtureGallery.FitLibraryFixtures.CalculateFixture]]!-) that has an expected value of -!'''!- true -!'''!- for each calculation. -!

# section Table Format
!3 !-Table Format-!
!- The first row of the table is the fixture class name. After that, the second row contains names for input parameters. All rows after that specify values for the input parameters. -!

{{{

# section Fixture class
!3 !-Fixture class-!
!- The fixture class should extend -!'''!- fitlibrary.ConstraintFixture -!'''!-. It should declare a boolean method with a name concatenated from all parameter names (in this case -!'''!- firstPartSecondPart -!'''!-). -!
