Their goal is not just to "find bugs", but to **guarantee product quality and delivery stability**. --- ### How the interaction happens 1. **Before development starts** - QA take part in analyzing requirements and discussing user stories. - Together with developers, they clarify acceptance criteria and test cases. - This helps avoid misunderstandings and reduces the number of defects. 2. **During development** - Developers write unit and integration tests and share builds with QA. - QA begin early testing (for example, on a test environment). - When a defect is found, they create bug reports describing reproduction steps and the expected result. 3. **After the task is finished** - QA run functional, regression, load, and other types of testing. - Developers respond quickly to the defects found, fix them, and pass the task back for re-verification. 4. **Before release** - QA run final checks (smoke/regression). - Developers help analyze complex bugs, log errors, and optimize the build. --- ### Key principles of the interaction - **Shared goal:** product quality, not "checking on each other". - **Early QA involvement:** the earlier testers get involved, the fewer errors reach production. - **Constant communication:** discussing bugs, logs, and environments directly, not through reports. - **Shared ownership of quality:** both developers and QA are responsible for stability. --- ### Conclusion The interaction between developers and QA is a **partnership, not an inspection**. When both sides are involved from the very start, the product becomes more reliable, the process more transparent, and testing faster and more effective.For the reviewerNote to the moderator (optional)Visible only to the moderator.
