Knapsack Pro wraps your current test runner(s) and works with your existing CI infrastructure to parallelize tests optimally:

- Dynamically splits your tests based on up-to-date test execution data
- Is designed from the ground up for CI and supports all of them
- Tracks your CI builds to detect bottlenecks
- Does not have access to your source code and collects minimal test data (with opt-in encryption)
- Enables you to export historical metrics about your CI builds
- Supports out-of-the-box any Ruby test runners, Cypress, Jest (and provides both SDK and API to integrate with any other language)
- Replaces local dependencies like Redis with an API and runs your tests regardless of network problems

The `knapsack_pro` gem supports all CIs and the following test runners:

- RSpec
- Cucumber
- Minitest
- test-unit
- Spinach
- Turnip
