Newest Build Subsets parallel CI nodes

Here you can check if all parallel CI nodes recorded tests timing data.

When you re-run CI build or run a new CI build for the same commit & branch & node total number, then the data below will be updated.

Collected Build Subsets 70 out of 70.

All CI nodes sent time execution data to Knapsack Pro API. Everything works!

The first CI node finished its work at 2021-04-19 17:42:28 UTC. CI nodes that finished at least 60s later are highlighted.

The reason for slow CI nodes might be too large test files (you can see the slowest test files at the bottom of the page when all CI nodes collected time execution data). You may want to try Knapsack Pro Queue Mode (Ruby) to solve a problem with the random performance of test files or your CI nodes. Learn more about dynamic test suite split here.

Note: if you run CI build for the same commit again (for instance when you retry CI build), then you will see build subsets updated below. Until retried CI build finishes work you may see highlighted build subsets.

Average time execution per collected CI node is 3 minutes 11.946 seconds.

The time gap between the finish times of the CI node that Finished First and the one which Finished Last is 3 minutes 27.802 seconds

Newest Build Distribution can be used for future CI build split

Build Distribution ID is the ID for the test suite split. You can see this ID in knapsack_pro logs as a test suite split seed.
Total time execution is sum of tests' execution times recorded across all parallel CI nodes.
Node max time execution is an estimated average time of running tests per CI node.
Distance is a time gap between average CI node time execution and the slowest CI node. The lower the better.

Build Distribution ID Node total Total time execution Node max time execution Distance
7b8639d0-818a-4dc7-85d0-48c1cc47282a 70 3 hours 43 minutes 56.178 seconds 3 minutes 11.946 seconds 4 minutes 0.091 seconds

The slowest test files for the Build Distribution

The slow test files are highlighted in yellow below.

Test files with higher time execution than 3 minutes 11.946 seconds are bottleneck because they take more time than expected execution time per parallel CI node.


You can enable auto split of slow RSpec test files by test examples on parallel CI nodes to run faster CI builds.

The more parallel CI nodes you use, the more test files will be split by test examples.

We recommend running at least 2 CI builds after you increase the number of parallel CI nodes. This way Knapsack Pro API can learn about your test examples defined in the slow test files to split tests better in future CI builds.
