Revamp test results with a powerful new UI (filtering, grouping, export)

[CorneRotterdam]

Together with a colleague, I’ve built a fresh, modern UI for the C# extension. It’s inspired by the error pane in Mendix Studio Pro, but taken several steps further with a strong focus on productivity, performance, and developer ergonomics.

Key features

• Complete overview of all failed, passed, and skipped test cases
• Powerful filtering via text input or buttons, including smart presets for quick access
• Bookmark issues to keep important findings front and center
• Export filtered results to CSV for reporting or further analysis
• Select one or more issues and generate a Markdown template, ready to drop into your issue-tracking platform
• Manual refresh to stay fully in control of your data
• Sortable columns (ascending / descending) for every data field
• Advanced grouping by module, category, rule, or severity

Performance-first design

This UI is built to stay fast—even on less powerful machines:

• Intelligent caching of rules, issues, statistics, and error details
• Extensive memoization to avoid unnecessary re-renders
• Virtual scrolling for smooth handling of large data sets

Built for keyboard heroes

• Multiple keyboard shortcuts to navigate and manage issues at speed

What’s next

This UI is not limited to the C# extension. I’m planning to implement the same experience in the TypeScript extension, bringing the same level of insight, performance, and usability to Mendix 11 as well.

Overall, this UI turns the C# extension into a much more powerful, scalable, and developer-friendly tool, helping you find, understand, and act on issues faster than ever.

Looks great Corne! Will have a look and merge next week

I have been using this version of the MxLint UI on multiple occasions and I can vouch for the improved scannability of the overview, the extra features such as exporting selected items as Markdown improve the developer experience and save time and effort

Nice job guys! Thanks a lot for the contribution. Will make sure we keep this in the new rebuild to web-extension. #28
