RCs over PRs: How RC testing aligns velocity and quality
PR testing sounds fast, but often delays releases with flaky tests, infra strain, and unclear failures. RC testing validates a stable build before release—cutting noise, reducing rework, and aligning QA and dev around quality that scales.

How to write an effective test coverage plan
Too many test suites collapse under scale because they lack a clear plan. Discover how to build a test coverage roadmap around workflows that matter, prioritize by impact, and maintain alignment with real product usage as your app grows.

What happens in orgs where teams outsource test creation but take maintenance in-house
Outsourcing the creation of your automated end-to-end tests and then handing them to your in-house team might seem like a good idea. Here's why your expectations likely don't match reality.

Catching bugs with regression testing is not solving your real quality problem
Don't stop at detecting bugs. Get to the root of your quality problem and prevent bugs from showing up in the first place.

Six metrics to gauge the real impact of test coverage
Counting tests isn’t the same as understanding your test coverage. These six metrics track signal quality, flake rates, skip rates, and workflow alignment to show whether your coverage helps you catch bugs early—or just slows your team down.
Culture of quality
What happens when QA is responsible for testing
When QA teams own end-to-end testing without the right systems, test maintenance takes over and coverage stalls. Give them the tools to do what they do best: catch meaningful bugs before they reach production.

Why you need separate end-to-end tests for each testing environment
Every environment is different — that’s the point — so your end-to-end tests have to be different too.

Flaky test coverage is fake test coverage
When automated tests are in working order they provide engineers with rapid feedback on features that are still in development. When they're flaky — when they repeatedly fail without finding a bug — they lose any value to developers, and they're a liability to the team.
