# Advanced Test Capabilities

TestFirst Editor supports advanced testing scenarios that go beyond basic automation.

You can simulate real-world user behaviour, handle multiple sessions, and build dynamic, reusable tests, all within a single flow.

* Test content in [**iFrames**](/testfirst-editor/advanced-test-capabilities/iframe-support.md)
* Build dynamic tests with [**dynamic selectors**](/testfirst-editor/advanced-test-capabilities/dynamic-selectors.md) and [**variables**](/data-repository/data-repository/variables.md)
* Reuse logic with [**fragments**](/testfirst-editor/fragments.md)
