Regression Testing Jobs

Regression Testing is an integral part of software engineering. It can be used to identify defects and bugs, uncover unexpected results in data, and help improve the quality of releases. Regression testing is based on rerunning tests that were previously carried out, such as unit tests, to confirm the feature or product's performance. Most of the time, this involves returning to a previously working version to make sure subsequent changes have not impacted its performance or reliability.

A Regression Tester is an essential member of any software engineering team since these tests help detect bugs in the software or product development process quickly and in a timely manner. They then use test coverage techniques such as benefit/risk analysis and random testing to ensure the best possible quality assurance level. They also ensure that regression-related risks are escalated and mitigated in a timely manner.

Here's some projects our expert Regression Testers made real:

  • Use of algorithm data fusion techniques for binary classification
  • Performance analyses of web applications
  • Identification and implementation of security features into existing systems
  • Detection and debugging errors within complex code written in different languages
  • Verification of expected outputs against actual results

    I need a detail-oriented tester to put my web application through its paces on both Chrome and Safari. Although it runs in the browser, many users will access it from mobile devices, so please include responsive checks on iOS and Android handsets and tablets. Here’s what I expect you to handle: • Create a concise test plan outlining functional, usability and UI scenarios. • Execute manual and, where helpful, automated tests—tools like Selenium WebDriver, Cypress or BrowserStack are fine as long as I can run them later. • Log every defect in my Jira board with clear steps to reproduce, expected vs. actual results, environment details, and supporting screenshots or screen-capture video. • Retest fixes and update the ticket status until each issue is clo...

    I’m ready to put my Android app through a full round of quality assurance focused on phones only. The goal is to surface functional bugs, uncover usability snags, and benchmark real-world performance before the next release. Here’s how I picture the collaboration: • You’ll create (or adapt) a concise test plan that explains the scenarios you’ll run, the devices you’ll use, and the metrics you’ll capture. • During execution you’ll track issues in a shared bug tracker, supplying clear steps to reproduce, screenshots or screen-records, and severity labels. • A short usability summary—what feels intuitive, what confuses first-time users, and quick-win suggestions—will round out the report. Please feel free to ment...

    I need a meticulous manual tester to run full functional testing on my Windows-based desktop application. The build is stable but hasn’t yet been exercised outside the development team, so I’m looking for someone who can approach it with a fresh set of eyes, follow typical user flows, and uncover anything that could block a smooth release. You will install the latest installer on your own Windows machine, explore every feature, and record all behaviours that deviate from the expected results. Clear, reproducible steps and supporting screenshots or short screen recordings are vital so my developers can fix issues quickly. I’m particularly interested in edge-case scenarios—unexpected inputs, window resizing, simultaneous actions—that automated scripts may miss....

    My development team is about to enter the quality-assurance phase and I need a dedicated tester to take charge of both manual and automated testing. The project already has running builds and clear functional requirements; what it lacks is a fresh set of eyes to uncover edge-case defects and to put reproducible, automated safeguards in place for future releases. Here’s what I’d like from you: • A concise test strategy and risk-based test plan covering functional, regression, usability and performance angles. • Hands-on execution of exploratory and scripted manual test cases. • Creation of maintainable automated suites (for example, Selenium, Cypress, Playwright or a framework you recommend) that can run on every build. • Clear bug reports—with...
