Tags help you organize your Scenarios. You can associate multiple tags with a scenario. Here are some of the possible ways in which you could use tags to categorize your tests:

• Features (e.g. reporting, accounting, auditing).
• Test characteristics (e.g. slow, fast).
• Type of test (e.g. smoke, regression).

Twist makes it possible to run all scenarios associated with one or more tags. For example, you could run all tests that have that have the tags: accounting, slow , and regression.
