Slow Test Review Initiative

[kenodegard]

What?

A weekly automated process to identify and track the slowest tests in the conda test suite for review and optimization.

Why?

• Slow tests impact CI turnaround time and developer productivity
• No systematic process exists to identify and address slow tests
• Test duration creep happens gradually without visibility
• Some slow tests may indicate underlying code issues worth investigating

User impact

• Faster CI feedback loops for contributors
• Reduced resource consumption on CI runners
• Better test suite maintainability

Goals

• Establish automated weekly identification of slowest tests
  • Enable durations
  • Sync slow-tests.yml
  • Sync slow-tests.yml and enable collecting test durations #6031
• Create a backlog of slow tests for engineers to claim and optimize
  • slow tests are added weekly to this epic as sub-issues
• Reduce overall test suite duration over time
