What is it?

Hydra Lab helps teams turn the test devices and machines they already own into a shared, cloud-style testing platform. It uses a center-agent design: a central Spring Boot service manages devices, test tasks and results, while agents running on machines attached to devices connect back to it.

The framework runs Android Espresso tests and Appium (Java) tests across Windows, iOS, Android and browser targets, and also supports XCTest, Maestro and Python runners according to its platform matrix. It includes a web portal for viewing connected devices, triggering runs and inspecting results, and it can store test files on local disk or Azure Blob Storage.

Beyond scripted tests, Hydra Lab offers case-free automation such as Monkey testing and smart exploratory testing that does not require hand-written test cases. A prebuilt Docker image bundles the center and an agent for quick evaluation.

  • 03Supports XCTest, Maestro and Python runners on the platform matrix.
  • 04Web portal for device status, test task triggering and result visualization.
  • 05Case-free Monkey and smart exploratory testing.
  • 06Stores test files on local disk or Azure Blob Storage.

Use cases

  • Mobile teams who want to run tests on their own Android and iOS devices in a shared pool.
  • QA groups building an internal test lab on Windows, Mac or Linux machines.
  • Teams looking for crash-finding exploratory testing without writing test cases.
