Since then, some platforms are starting to provide remote debugger capabilities, as part of their platform toolset. weinre reuses the user interface code from the web inspector project at WebKit, so if you've used Safari's web inspector or Chrome's Developer Tools, weinre will be very familiar. In normal usage, you will be running the client application in a browser on your desktop/laptop, and running a target web page on your mobile device. weinre does not make use of any 'native' code in the browser, it's all plain old boring JavaScript. -

Diffblue Cover
Diffblue
Diffblue Cover analyzes your existing Java program and writes unit regression tests that reflect the current behavior of the code. The CLI tool works 100% autonomously, configuring itself from your Maven or Gradle environment. By bringing automation to the test-writing process, the CLI tool provides a speed boost for organizations that are working towards achieving DevOps goals like CI/CD. Since it fits into a CI pipeline, the CLI tool protects the whole codebase from regressions by shifting testing left. Diffblue Cover's unit regression tests run fast and verify new code changes immediately, helping users detect undesirable changes in the code’s behavior as early as possible, when they're the quickest, easiest, and cheapest to fix. And tests are automatically maintained, saving teams even more time.Starting Price: Free -
