Layer caching is one of the best features of building Docker images. Can the same technique be used when executing commands in VMs for CI builds?

Last year, we began building a tool to solve common pain points that engineering teams encounter in their builds and with their test suites. Captain is an open source CLI that can detect and quarantine flaky tests, automatically retry failed tests, partition files for parallel execution, generate comprehensive test failure summaries, and more.

Last year, we began building a universal test runner that executes test suites as distributed workloads. It’s universal in that it’s one CLI that can be used with many existing testing frameworks. After a thorough beta testing period over the past several months, we’re excited to announce the generally available, open source release of ABQ. It’s the best tool for splitting test suites into parallel jobs in CI.
