Agentic Test Generation

Instead of recording a user flow in the browser, you can describe what you want to test in plain English and let Claude generate the test for you.

Before using this feature, set up the Claude Code integration first. See Claude Code Integration for installation and authentication.

Creating a Test

In Claude Code, use the /decipher-qa slash command followed by a description of what you want to test:

/decipher-qa test the signup flow through email verification

Claude will:

Explore your codebase to understand your pages, components, and routes
Generate test steps based on your description
Run the test on a cloud-hosted browser
Validate each step and capture screenshots

You don’t need to specify selectors, URLs, or step types — Claude figures those out from your code.

Describing Your Test

Write your prompt like you’d explain the test to a teammate. Be specific about what the test should do, but you don’t need to be technical. Good prompts:

Prompt	What Claude generates
`test the login flow with invalid credentials and verify the error message`	Navigate to login, enter bad credentials, submit, assert error message appears
`test creating a new project, editing its name, then deleting it`	Full CRUD flow across multiple pages
`test the billing settings page as an admin user`	Authenticated flow using a login identity
`test that the search bar returns results for "shoes"`	Navigate to search, type query, assert results appear

Tips for better prompts:

Mention the specific page or feature (e.g., “the settings page”, “the checkout flow”)
Include what you want to verify (e.g., “verify the success message appears”)
Mention the user role if the flow requires authentication (e.g., “as an admin user”)

Generating Multiple Tests

You can ask Claude to generate several tests at once:

/decipher-qa create tests for the full CRUD flow on the projects page:
- creating a new project
- editing a project name
- deleting a project

Claude will generate and validate each test independently. You can also apply changes across existing tests in bulk from the Decipher dashboard using “Ask for Changes” — describe a modification in natural language and apply it to multiple tests at once.

Automatic Self-Fixing

When a generated test fails during validation, Claude automatically diagnoses and fixes the issue:

Decipher’s agent runs each step and flags any failures with diagnostics and screenshots
Claude analyzes the failure — wrong selector, missing wait, incorrect assertion, etc.
Claude fixes the failing steps
Validation resumes from where it left off, without re-running the entire test

This loop continues until the test passes or requires your input. If Claude can’t resolve a failure, you’ll see the failure details and screenshots so you can edit the step manually and resume.

Modifying Tests with Natural Language

After a test is created, you can modify it without manually editing steps. Use “Ask for Changes” in the Decipher dashboard or ask Claude directly:

/decipher-qa add an assertion to verify the user is redirected to the dashboard after login

You can reference specific steps in your request:

/decipher-qa change step 3 to click the "Save" button instead of "Submit"

When to Use Claude vs. Recording

Scenario	Recommended approach
You know the flow but don’t want to click through it	Claude — describe it and let Claude generate the steps
The flow involves complex interactions you’d rather demonstrate	Recording — click through it with the Chrome extension
You want to generate tests for multiple flows quickly	Claude — describe them all in one prompt
You need to test a page that isn’t built yet	Claude — generate tests from your code before the UI is live
You want to capture exact timing and interactions	Recording — the extension captures your real behavior
