3.0 roadmap

[rtsao]

Replacing Electron with headless Chrome laid down a lot of the groundwork to a fully Chrome DevTools Protocol (CDP) based solution.

Guiding principles

• Implement everything in an environment-agnostic fashion via CDP
• Support only platforms that implement CDP (e.g. Node 8+, Chrome)
• Good experience out of the box with no test runner
• Progressive enhancement via test runners that use CDP
  • Runners can imperatively change behavior via CDP Runtime.evaluate before tests are run
    • Skipping tests, different test output format, etc.
• Designed for async functions
• Designed to be integrated into larger frameworks
  • Being un-opinionated about build tooling is imperative
  • Good programmatic APIs, optional nice machine-readable test output
• Performance
  • Multicore and parallel testing
  • Support incremental test running
