| [Visual Testing](/web-testing/advanced-features/visualtesting.md)          | Comparing a page against a saved baseline image      |
| [Functions](/web-testing/advanced-features/functions.md)                   | Grouping steps into something reusable               |
| [Import and Export Scripts](/web-testing/advanced-features/importsteps.md) | Moving scripts between projects as files             |

None of these are required to run a test. Each one solves a problem you will meet as your test suite grows.
