Keeping testing part of everyday work

Testing during execution goes beyond checking if features work technically. The scope of testing should always match the size and importance of the feature. Larger features often require more test scenarios, broader device coverage, and deeper validation, while smaller improvements may only need lightweight checks.

Start with the most critical user journeys that directly impact key metrics or represent core value. For large features, test these flows thoroughly under different conditions, including edge cases like poor network connectivity or incomplete data. Smaller fixes can be tested more narrowly but should still confirm they do not break existing functionality.

Involve team members beyond QA in proportion to the work. Developers can uncover technical edge cases, designers can flag usability issues, and product managers can verify business logic. Bigger features benefit from more perspectives, while smaller items might only require a quick review.

Plan testing throughout the sprint, not just at the end. Even for small features, early checks prevent rework. For large initiatives, continuous testing across iterations helps catch fundamental issues before they compound. This keeps quality high without overwhelming the team, regardless of feature size.^[1]
