Knapsack Pro
Knapsack Pro
Queue mode - dynamic tests allocation across parallel CI nodes playThe recommended way to run tests - it ensures all parallel CI nodes finish work at a similar time. It auto balances tests split between parallel CI nodes to get the fastest CI build time.Queue Mode solves CI node bottlenecks impacting your parallel tests split:
|
|
Regular mode - test suite split based on time execution playIt is deterministic way of running tests. It generates subset of test suite per CI node before running tests. Can be used with knapsack_pro ruby gem. |
|
Auto split slow test file between parallel CI nodesA single test file can be auto split by test examples between parallel jobs. |
|
Automated tests time execution recording |
|
Test suite split based on most up to date tests time execution data |
|
Support for short-lived CI nodesKnapsack Pro is fault-tolerant and can withstand possible CI instance preemptions (shut down) when you use highly affordable CI nodes like Google Cloud Preemptible VMs or Amazon EC2 Spot Instances. |

Supported CI providers |
|
|
It works with all CI servers (setup with ENV vars) Knapsack Pro works with any CI provider. The CIs listed below are the ones whose environment variables are auto-detected by Knapsack Pro. If you are using a different CI provider, you can still configure Knapsack Pro by following the installation guide. |
