The field section is the main section of an equivalence class table. The field section contains many field sub sections. It is a kind of parenthesis around fields and a grouping of element.
This section contains all the equivalence classes for one single field.
Multi row sections have multiple rows. One header row and 1..n data rows.
The MultirowSections could be used for your own purpose. These sections are not directly supported by the test data generator like the field sections. But each data generator has access to the data from the multi row sections.
The tag section is used to add tags/labels to test cases. These tags could be used for filtering. If a test case uses references, all tags are collected of the chained test cases and could be filtered.
The filter section defines filter for test cases. The filter works only in the master test case. So if you have test cases which uses references, the filter in a referenced test case is not executed.
The generator switch section defines generators to be switched off. So you can switch of generators on a test case level.
Single Row Sections
Single row sections are sections which have only one row.
The image shows the execute section. In this example the test case '2' in column 'G' is set to 'F' which is false. So this test case would not be executed.
This section is the opposite of the ExecuteSection. If in the ExecuteSection a test case is set to a true value this test case will be generated. If it is set to a false value the test case is not created. But if this test case is referenced from an other table it is used and the data is generated. The NeverExecuteSection works the other way around. If this is set to a true value for a test case, the test case is created. But if this test case is referenced from an other test case, the referencing test case is not created.
The image shows the multiplicity section. In this example the test case '1' in column 'f' is set to '10'. This means the data generator will create 10 of these test cases.
The summary section is not used by the generator. Is only for the user.
