Integration/E2E TestingHow to Diagnose Flaky Tests
Why scale makes tests flaky, the usual causes from timing and test data to hidden bugs and external services, and how flaky tests wear down a team's trust in CI.

Integration/E2E TestingHow to do DORA Metrics Right
How to calculate the four DORA metrics (deployment frequency, lead time for changes, time to restore service and change failure rate) and what they actually say about a team.
-
Integration/E2E TestingHow Microservices Communicate with Each Other
REST, gRPC and messaging through Kafka or RabbitMQ compared, then the hard part: testing those calls when every service depends on others, against real dependencies instead of mocks.
-
Integration/E2E TestingWhat's the real ROI of writing Mocks?
When mocks earn their cost and when they hide integration bugs, why the gap widens once AI agents write the tests too, and two alternatives: local replication or shared environments with isolation.

Integration/E2E TestingIs WASM the future for Kubernetes Operators?
What WebAssembly offers Kubernetes operators, a walkthrough of building and deploying a WASM filter for Envoy with Istio, and the reasons for skepticism about WASM on the server.

Integration/E2E TestingOpenTelemetry and Go: a whole new eBPF world
How eBPF brings automatic OpenTelemetry instrumentation to Go services without code edits, and how the project kept it stable across changing structs, stripped binaries and monotonic time.

Integration/E2E TestingMocking and Testing 3rd-party APIs with Sandboxes
Why third-party APIs are hard to test against, how the API mocking frameworks MockServer, WireMock, Mockoon and Mountebank compare, and how sandboxes switch tests between mocks and real APIs.

Integration/E2E TestingUsing Signadot Sandboxes for API Testing
A tutorial that sets up Signadot sandboxes, changes an existing API, and tests it through a sandbox preview URL and Postman while every other service in the cluster stays shared.
-
Integration/E2E TestingWhy large engineering teams are testing on Kubernetes
How teams like Reddit, Eventbrite and Prezi moved development from laptops to Docker Compose to remote Kubernetes environments, and how developers can share one cluster for testing.

Integration/E2E TestingIntroducing a New Paradigm for End-to-End Feature Testing In Microservices
Signadot's feature testing launch: route groups join labeled sandboxes from several pull requests so a feature can be tested end to end from the front end and previewed before merge.

Integration/E2E TestingTutorials/GuidesGuide to Shift-left Test Approach in Kubernetes
Why shift-left testing is harder with microservices on Kubernetes (separate pipelines, many languages, testing in the full stack), and how flexible pipelines and fast test environments help.
