How to run Ruby on Rails tests in Minitest on Github Actions? What to do if tests are slow? How to manage complex workflows? You can use Github Actions build matrices to divide Minitest files between jobs and run the test suite much faster.
If your Minitest tests are taking dozens of minutes and you would like to save some time for your Ruby engineering team then you could use tests parallelization on your CI server.
To run tests as fast as possible you need to split them into equal buckets (into parallel jobs). But how to do it? Some of the test files can be super fast to execute, other Minitest files can take minutes if they run system tests (E2E tests).
There is also an aspect of preparing the test environment for each parallel job. By preparing I mean you need to clone a repository, install ruby gems or load them from a cache, maybe you need to load some docker container, etc. This can take various amounts of time on each parallel job. Random network errors happen like network delay to load cached gems, or maybe Github Actions from time to time will start one of your jobs late compared to others. It’s an inevitable issue in the network environment and can cause your tests to run for a different amount of time on each parallel job. This is visible on the graph below and it causes the CI build to be slower.
A common challenge that cloud native application developers face is manually testing against inconsistent environments. GitHub Actions can be triggered based on nearly any GitHub event making it possible to build in accountability for updating tests and fixing bugs.
One of the oldest NetLicensing Client libraries for C# (with the first GitHub push made on Oct 2, 2013) was not available in one of the essential package managers for .NET
Five easy ways to automate 🤖 your software development process with Github Actions. Lean how to build CI/CD pipelines and other awesome DevOps workflows.
DevOps and Cloud computing are joined at the hip, now that fact is well appreciated by the organizations that engaged in SaaS cloud and developed applications in the Cloud. During the COVID crisis period, most of the organizations have started using cloud computing services and implementing a cloud-first strategy to establish their remote operations. Similarly, the extended DevOps strategy will make the development process more agile with automated test cases.
