A Test Case is a named set of steps for testing a single feature or characteristic of the system under test. Test cases are associated with a product, and can have one version per product version. They can be organized via suites and/or tags, and can have file attachments. Preconditions, assumptions, and other preliminary information can be provided in the case’s description. A test case can have any number of steps; each step has an instruction and an expected result.
A Tag can be associated with one or more test cases as a way to organize and filter them on any number of axes.
By default, tags are product-specific; global tags can also be created and managed via the tag management UI.
