Does GoCD support parallel builds?

[Michael Baldry]

And by this I mean, I mean something similar to CircleCI, where you can say a project has 4 agents and then it runs each one with an ENV variable set to say what agent number it is and you can split your tests by the number, to run a single test suite in a quarter of the time (in theory).

If not, is there another way to achieve this goal?

Many thanks!

You can specify your jobs to run on multiple agents. The build will run with 2 additional environment variables GO_JOB_RUN_INDEX and GO_JOB_RUN_COUNT to indicate the number of agents, and the index of the current agent. You may use these variables to partition your tests as you see fit.

For reference, the GoCD team uses this code to partition tests across several agents.

Oh awesome. I didn't spot that in any of the documentation but sounds like it works exactly the same as. Thank you
