FAQs

Clearly define what you want the QA engineer to test. List all the features and functions that need checking. Be specific about the platforms or devices you'll use. This helps the QA expert understand your needs and focus on important tasks.
Start with what your product or app does. Share who your users are and what they care about. Include any issues you've found before or things that need special attention. The clearer you explain, the better the QA expert can help you.
A user story is a short description of what a user does or needs. It helps QA engineers know what to test based on real user actions. With user stories, everyone gets on the same page about user expectations and needs.
Collaborate with the QA expert to choose the tools. Consider what your team already uses and loves. The right tools make testing smooth and effective. Tools can vary for web, mobile, or backend testing.
Milestones show progress and help keep the project on track. They break big projects into smaller parts that are easier to manage. QA experts can test each part as it’s done. This way, any problems can't add up unnoticed.
A test plan is like a roadmap for testing. It includes what will be tested, how, when, and by whom. With a plan, you make sure nothing gets missed. It helps everyone understand the goals and timelines of the testing work.
Set a regular schedule for updates and feedback. Use simple language and encourage questions. Tools like email, chats, or video calls can help. Clear communication keeps everyone informed and the project moving smoothly.
Define what a successful outcome looks like from the start. Use metrics like the number of bugs found, resolved, and remaining. Discuss quality improvements with your team. Track these to see how testing helps your product improve.
Be clear, specific, and kind with your feedback. Point out what you liked and what could change. Use examples to explain your points. This helps the QA expert understand your view and keep improving their work.
