Best Software Testers and QA Experts

What a good QA service includes

Testing gigs range from a quick check of one feature to full test cycles. Check that the service states:

• Scope: which features, pages or flows will be tested.
• Devices and browsers covered.
• Type: manual, automated, usability or performance.
• Test cases: written steps, or exploratory testing.
• Bug reports with clear steps and screenshots or videos.
• Retesting after fixes.
• Timeline and confidentiality.

Decide what kind of testing you need. Functional testing checks that features work as described. Usability testing checks whether real people can figure them out. Compatibility testing checks different devices and browsers. Many small projects need a mix, and saying which matters most helps the tester spend their time where it counts, especially when the budget only covers a few days of testing.

How to brief a tester

1. What the product does and who uses it.
2. The key flows: sign-up, purchase, booking, search.
3. How it should behave, including rules and limits.
4. Test environment and test accounts.
5. Devices and browsers to cover.
6. Where to report bugs: a spreadsheet, a tracker or a shared document.

Ask for bugs to be ranked by severity. A checkout that fails matters more than a misaligned icon. A ranked list helps your developer fix the important problems first when time is short.

Repeat a short test before every major release. The most common problems appear when a new feature quietly breaks an old one. A simple list of core flows checked each time catches most of them.

What drives the price

• size of the product and number of flows
• number of devices and browsers
• manual versus automated testing
• writing test cases versus exploratory testing
• retesting and repeat cycles
• specialist testing such as accessibility or performance

Red flags

• Vague reports like "it doesn't work" with no steps.
• No list of devices tested.
• Testers asking for real customer data or live admin access.
• Hundreds of trivial reports with the serious ones buried.
• No retesting offered.

For building or fixing the product, see our software development guide and mobile app development guide. For testing usability with real people, read our UX design guide.

Keep the bug list in one shared place that both the tester and the developer can see, such as a simple spreadsheet or a free issue tracker. Each bug should have a status: new, being fixed, fixed, or confirmed. This avoids bugs being reported twice, forgotten, or marked fixed when they are not. It also gives you a clear picture of how close the product is to being ready for release.

Quick pre-order checklist

• I have listed the key flows and expected behavior.
• Testing happens on a test copy with test accounts.
• The device and browser list matches my users.
• Bug reports will include steps, severity and screenshots.
• Fixes will be retested.
