FAQ
What will I receive in the bug report?
You’ll receive a detailed bug report that includes issue descriptions, severity levels, step-by-step reproduction instructions, and annotated screenshots.
How long does testing take?
Testing time depends on the complexity of your website, app, or software. Generally, it ranges from 1 to 5 business days based on the selected package.
Can you test specific features instead of the whole website or app?
Absolutely! If you want to test only certain functionalities or sections, just let me know, and I’ll tailor the testing process accordingly.
Do you offer re-testing after fixes?
Yes! I can retest the bugs after your team has fixed them to ensure they are properly resolved. Re-testing is included in the Premium Package or can be purchased separately.
Can you test both websites and mobile apps?
Yes! I test web applications, SaaS platforms, mobile apps (iOS & Android), and desktop applications for compatibility, functionality, and usability.
Do you provide test case documentation?
Yes! If you need structured test cases, I can create them and execute the test plans accordingly. Just let me know before placing the order.
Do you also check for security vulnerabilities?
While my primary focus is on QA testing, I am also a penetration tester and can identify basic security flaws manually. For a detailed security assessment, please check my separate security testing gig.
What devices and browsers do you test on?
I test on Windows, macOS, Android, and iOS across popular browsers like Chrome, Firefox, Safari, Edge, and Opera to ensure cross-browser compatibility.
How can I request additional testing beyond my package?
If you need additional testing hours, bug fix verification, or testing on specific devices, you can purchase extras or message me for a custom offer.
