'''!- RowFixture -!'''!- tests dynamic lists of objects. It will compare the expected list (FitNesse table) with the actual result (from fixture code) and report any additional or missing items. -!

# section Table Format
!3 !-Table Format-!
!- The first row of the table is the fixture class name. The second row describes the structure of objects in the list (the properties or methods that you want to verify). All rows after that describe expected objects in the array. -!

!-The fixture class should extend -!'''!- fit.RowFixture -!'''!- and override the following two methods:-!

# section Notes
!3 !-Notes-!
!-If the object has some properties that can be considered part of the identity (such as a primary key), list those properties to the left, before auxiliary properties. This will make error reports easier to read. Consider the -![[!-Figure 1-!][<UserGuide.FixtureGallery.BasicFitFixtures.RowFixture#figbasicfixturesrowmap]]!- &mdash; the error is absolutely the same in both cases, but because of the column order one test report clearly identifies the offending cell and the other just reports that a whole row is missing. -!

!-The -!'''!- query -!'''!- method does not allow you to pass any additional arguments. For more information on how to parameterise this list, see -![[!-Fixture Arguments-!][<UserGuide.FixtureGallery.ImportantConcepts.FixtureArguments]]!- .-!

!-The order of elements in the list is irrelevant, -!'''!- RowFixture -!'''!- will ignore it. -!

# section Usage
!3 !-Usage-!
!- Use -!'''!- RowFixture -!'''!- to test and verify lists of objects, or to execute a method on every object in the list. -!

!- Do not use -!'''!- RowFixture -!'''!- when the element order is important. Use -!'''!- ArrayFixture -!'''!- instead (see -![[!-ArrayFixture-!][<UserGuide.FixtureGallery.FitLibraryFixtures.ArrayFixture]]!-). -!
