Important journeys are often tested manually because writing robust automation takes specialist time. When those journeys change, a video or written checklist cannot run again or tell the team exactly what failed.
Build
TestTwin
If you can use your app, you can test your app.TestTwin converts a successful manual journey into a maintainable automated test. It infers actions and assertions from real page behavior, identifies stable element targets, and keeps the original recording available when the generated test needs repair.
From friction to a clear outcome
TestTwin converts a successful browser journey into a maintainable test. It infers actions, stable targets, expected outcomes, and useful assertions, then preserves the source recording for review and repair.
Turn a manual checkout check into regression coverage
- 1
Record a successful product-to-payment journey
- 2
Mark the expected cart, total, and confirmation states
- 3
Review selectors, data, assertions, and edge cases
- 4
Run the test against the target environment
- 5
Export or maintain the test with its source recording
How TestTwin works
- 01
Record a complete user journey and its expected result.
- 02
Review generated steps, assertions, test data, and stable selectors.
- 03
Run the test repeatedly or export it to the team’s existing automation stack.
Core capabilities
Action generation
Turns navigation, clicks, typing, selection, and uploads into executable steps.
Stable selectors
Finds resilient semantic targets and flags fragile element references.
Assertion inference
Suggests visible, URL, value, network, and state expectations from the journey.
Edge-case prompts
Highlights empty, invalid, slow, alternate, and permission-dependent paths to add.
Quality checks
Can include accessibility checks and expected API behavior around key actions.
Framework export
Produces a starting point for Playwright, Cypress, or Selenium workflows.
Best use cases
- ✓Checkout regression testing
- ✓Critical SaaS workflow coverage
- ✓Turning exploratory QA into automation
Expected outputs
- →Executable browser test
- →Given/When/Then specification
- →Playwright, Cypress, or Selenium export
What changes for the team
- ↗Convert exploratory QA into repeatable coverage
- ↗Give developers readable evidence when a test fails
- ↗Start automation from a real user journey instead of a blank file
Safe by design
- ✓Test data and target environment are explicit before execution
- ✓Destructive production actions are blocked or approval-gated
- ✓Generated selectors and assertions stay reviewable by the team
TestTwin keeps the original human session connected to the generated test, making intent and future repair easier to understand.

TestTwin consumes the same structured DOM events, timeline, context, snapshots, and safe execution primitives as the rest of TabTwin—without requiring another extension.
