A Good Order To Read
STEP 1
Managing the Lifecycle of Test Data
Many unstable tests fail because of data, not assertions. Teams need rules for creation, sharing, cleanup, and retention.
STEP 2
Connecting Synthetic Monitoring and Canary Testing
Testing should not end at pre-release CI. This post explains how to connect synthetic monitoring with canary rollout validation.
STEP 3
Defining a Release Candidate Test Cutline
Running more tests is not the same as shipping safely. This guide explains how to define a release-candidate cutline around real risk.
