A practical guide to testing internal products without overdoing it.

1. Baseline Evaluation

Before deciding how much to test or what to improve, understand your current state.

• Unit tests
• API / Service tests
• Functional UI tests
• Automated tests
• Separation of duties (developers vs testers)
• Deployment + rollback steps
• Performance checks
• Security checks
• UAT process (high-level)

Questions to ask yourself:

• Where do issues usually appear today?
• Which testing layers exist and which are missing?
• Where does your team spend the most testing time?
• Who currently owns which parts of testing?
• How often do you rely on users to surface issues?
