MSTest 3.4 introduces several enhancements including nine new code analyzer rules aimed at ensuring adherence to best practices, allowing better assertion usage and design preferences. It now supports Single Threaded Apartment (STA) threads, improving the execution experience for UI tests and enabling timeouts for crucial fixture methods such as cleanup and initialization. Removing unnecessary project boilerplate enhances Playwright and Aspire testing. The MSTest SDK has become easier to use, as developers no longer need to add certain using directives, and sample projects are also improved for clarity.
