This change improved test isolation and reliability, reducing flaky results and accelerating feedback cycles for formatting tests. The work also included documentation of the test infra changes and clean-up related to the TestEnvironment configuration. No major bugs were closed this month; the emphasis was on infra stability and quality improvements that enable more predictable test outcomes and faster iteration for formatting-related work.

May 2025 performance snapshot across JetBrains/resharper-unity and resharper-fsharp. Focused on test framework standardization, cleanup, and maintainability improvements that reduce costs and improve reliability of plugin tests.

April 2025: JetBrains/resharper-unity Unity integration test framework modernization and test data alignment completed. The effort migrated test infrastructure to PerTestProtocolTestBase, aligned with PerTestEnvironmentTestBase, and refreshed DOTS debugging gold files to reflect the current Rider Unity plugin testing protocol. These changes improve reliability, consistency, and maintainability of Unity integration tests, reducing flakiness and speeding CI feedback. No explicit bug fixes were required this month; the upgrades focus on stabilizing the test pipeline and data fidelity.

March 2025 monthly summary for JetBrains/resharper-unity focused on stabilizing and modernizing the test build workflow through a Build API facade rewrite. The central change refactors test build solution invocation by removing the unused 'project' parameter from buildSolutionWithReSharperBuild in the integration test base class, as part of adopting a new Build API facade to simplify and stabilize the test build process.

February 2025 performance summary: Executed two major modernization efforts across JetBrains/resharper-fsharp and JetBrains/resharper-unity to align test environments with the latest stable .NET 8 SDK, addressing SDK drift and data alignment to enable faster, more reliable releases. Key initiatives: - Rider-FSharp Test Suite: Modernized to .NET 8, updated test data and gold data (FSharp.Core) to reflect SDK changes, and added CompileOrder flags to stabilize test execution. - Rider Test Infrastructure (resharper-unity): Upgraded test environments to NET 8 across rider/src/test/kotlin, ensuring tests run against the current framework. - Coarse-grained modernization pattern: Replaced NET 5/6/7 usages with LATEST_STABLE across Rider tests where feasible to streamline future upgrades.
