UI5 Test runner

A self-sufficient test runner for UI5 applications enabling parallel execution of tests.

To put it in a nutshell, some UI5 applications have so many tests that when you run them in a browser, it ends up crashing. The main reason is memory consumption : the browser process goes up to 2 GB and it blows up. JavaScript is based on garbage collecting but it needs time to operate and the stress caused by executing the tests as well as the use of iframes do not let enough bandwidth for the browser to free up the memory.

This tool is designed and built as a substitute of the UI5 karma runner. It executes all the tests in parallel thanks to several browser tabs (which also reduces the total execution time).

💿 How to install

• Works with Node.js >= 24.11.1
• Local installation
  • npm install --save-dev ui5-test-runner@6
  • Trigger either with npx ui5-test-runner or through an npm script invoking ui5-test-runner
• Global installation
  • npm install --global ui5-test-runner@6
