Maestro.dev
Maestro supports repeatable interface testing for mobile and web apps, using readable YAML flows, command-line execution and continuous-integration workflows.
About this tool
Maestro executes user-interface tests expressed as readable YAML flows. It supports mobile and web applications, with command-line and desktop tooling for developing and running tests. The explicit flow definition helps a team inspect what an automated check actually exercises.
The platform extends its capabilities to emulator screen analysis, where pattern‑search techniques suggest additional test suites. Integration with continuous‑integration tools enables direct validation of UI changes as part of the build process.
What you can do
Readable YAML Test Flows
Tests describe interactions and checks in YAML, providing a versionable record of the intended user journey. Review the flow against actual requirements and meaningful failure cases.
Command‑Line Test Execution
Run generated or existing YAML test suites via a CLI, receiving comprehensive results that indicate pass/fail status and any errors.
CI Pipeline Integration
Connect Maestro.dev with CI systems to automatically trigger test runs and validate UI changes during each build.
Who is it for?
- A development team writes a test flow for a new iOS screen and runs it in the appropriate environment to check the intended interaction.
- QA engineers maintain a library of YAML test files for an Android app; they use the CLI to execute the suite nightly and review the summarized results for failures.
- A mobile team inspects emulator screen hierarchies with the available assistance and adds focused flows for previously untested interactions.
Before you choose
Confirm that the CI environment provides the necessary emulator or device configurations required for test execution.
Verify how the pattern‑search on emulator screens aligns with the project's design system to avoid irrelevant test suggestions.
Frequently asked questions
What input formats does Maestro.dev accept for test creation?
The described test definitions use YAML to express user-interface flows. Do not assume that uploading application source code automatically produces complete tests; inspect and maintain the actual interactions and assertions.
How are test results delivered after CLI execution?
After running a test suite, the CLI returns a structured report that includes pass/fail status, error messages, and any validation details for each test case.
Can Maestro.dev be used with both mobile and web applications?
Yes, the tool integrates with iOS, Android, and web application projects, allowing the same workflow for generating and running UI tests across these platforms.
