API testing upgrade, Thunders Copilot reasoning, and run comparison

TL;DR

API testing gains a full response inspector and assertions, Thunders Copilot streams its reasoning, and you can compare two runs side by side.

FEATURE
  • API testing: open the full response in an interactive inspector, extract any value as a variable in one click, and assert on status, headers, or body.
  • Copilot reasoning: Thunders Copilot streams its reasoning and actions in real time instead of a loading spinner.
  • Run comparison: compare two runs side by side, with step- and action-level diffs across screenshots, HTML, logs, and settings.
  • Console error detection: the QA Persona flags browser console errors during execution, even when the UI looks fine.
  • Re-run a failed run: re-run a whole failed test run directly, not just individual cases.
IMPROVEMENT
  • Test Set workspace: each Test Set gets its own view with pass rate, runs, and cases.
  • Multi-tab visibility: tabs appear in the preview header with page title and favicon.
  • Keyboard shortcuts: across the test case editor.
  • Accessibility options: an "Always" severity level and the RGAA 4 standard.
FIX
  • Variable placeholders: preserved in step inputs.
  • Date and iframe inputs: fixed date inputs on React apps and iframe fields on Firefox.
  • Azure DevOps: bug reports route the description to the correct field per work-item type.
  • Titles and popups: better auto-generated test-case titles, and more reliable handling of browser popups during runs.
