Customize the AI

Customize Test Companion to align with your organization’s specific standards and make your work faster using rules and workflows.

Test Companion works out-of-the-box with powerful built-in AI for common testing tasks such as generating test cases, writing automation code, fixing flaky tests, and debugging failures. No configuration is required to start using these capabilities.

However, every team’s testing environment is unique. Your organization may have its own frameworks, coding standards, naming conventions, folder structures, and recurring processes. Customization is essential for teaching Test Companion about these specifics, so it can produce outputs that align with your project from the very first attempt, instead of requiring corrections each time.

There are three layers of customization, and they work together:

Understand customization options

It is important to understand when to use which, as picking the wrong layer can lead to either overly rigid or inconsistent results.

Use Rules when you want to enforce guidelines that should apply to every interaction, such as coding standards or naming conventions. Rules operate silently in the background, and the AI follows them automatically.

Use Workflows when you need to execute a repetitive multi-step process, like generating regression tests from a template or setting up a new test suite for a feature. Workflows are explicitly invoked only when necessary.

Use Configuration when you want to modify how the extension functions, such as the AI’s interaction mode, its permissions for autonomous actions, browser viewport size, terminal behavior.
