Platform Engineering
A golden path is the recommended, paved workflow for developers on your platform — "create a new microservice," "onboard a new team," "deploy to production." If the golden path is broken, the entire engineering organization is blocked. This guide covers how to define, instrument, and
Platform Engineering
Crossplane turns Kubernetes into a universal control plane for infrastructure — but untested compositions are ticking time bombs. This guide covers the full Crossplane testing stack: unit-style testing with kuttl, Uptest for provider integration tests, composition validation with crossplane beta validate, and end-to-end infrastructure tests that provision real
CI/CD
Dagger.io flips the CI/CD model on its head: instead of YAML pipelines that are impossible to test locally, you write your pipelines in Python, TypeScript, or Go — and run them anywhere. The same pipeline runs on your laptop, in GitHub Actions, and in GitLab CI without modification. This
CI/CD
Both Dagger and GitHub Actions run your tests in CI. The difference is how you define and debug those pipelines.
Testing
Test interference is one of the subtlest sources of test suite unreliability. Tests that pass in isolation fail when run together.
Testing
Most teams treat test environment provisioning as an operations problem: file a ticket, wait for an engineer to spin something up, hope it matches what you actually need. Infrastructure as Code flips this. When your test environments are defined in Terraform, any team member can provision a complete, correctly configured
Testing
You've seen this failure mode. Tests pass in staging. The deployment goes out. Production breaks.
Testing
Bugs found in production cost 10 times more to fix than bugs found during development.
Testing
The most realistic test environment is production. Staging environments, no matter how carefully maintained, diverge from production over time.
Testing
Review apps — a dedicated deployment for every pull request — are one of the most effective ways to catch bugs before they reach your main branch.
Testing
Flaky tests that pass locally but fail in CI. Tests that corrupt shared state and cause downstream failures.
Testing
Environment drift is quiet. It doesn't announce itself. It accumulates through configuration changes, dependency updates, and infrastructure modifications — each individually harmless, collectively producing an environment that no longer matches what your tests expect. By the time drift causes a visible failure, tracing it back to its source is
