How it works

Symbol modeling
1

Create test inputs

Visually model test inputs for your Web application without writing code.

  • Create test inputs for Web UIs with Selenium-based actions.
  • Create test inputs for HTTP APIs: make requests and analyze responses.
  • Reuse and combine test inputs to create new ones.
2

Model E2E tests

Combine test inputs to create E2E tests as you know them.

  • Organize tests in test suites.
  • Execute tests against different browsers and environments.
  • Generate detailed test reports.

Learn behavioral models

Based on test inputs, an algorithm interacts with your application automatically: it creates tests by itself! See how your application reacts to inputs in different scenarios.

  • Verify system properties via temporal logic formulas.
  • Enrich existing test suites via model-based test generation.
  • Compare models against each other.
