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’m looking for an experienced game tester to put my project through its paces. The goal is to uncover bugs, balance issues, and usability friction early, so the development team can ship a smoother final build. You’ll receive the latest playable version, access credentials, and a concise feature list. From there, I expect: • A structured test plan outlining coverage areas (gameplay, performance, UI/UX, edge-case scenarios). • Daily bug reports with clear reproduction steps, screenshots or screen-captures, and severity ratings. • A short final summary highlighting critical blockers, overall stability, and any polish recommendations. Platform specifics are open—whether the build runs on mobile, PC, or console, I can provide the appropriate install ...

    I run a production Python pipeline that extracts structured data from complex technical PDF documents — detecting objects, tracing linear features, and measuring areas and regions — using a mix of vision LLMs and computer vision. It works and is deployed, but I need someone who can take real ownership and push accuracy, robustness, and cost in directions I can't get to fast enough on my own. The pipeline is staged: render the PDF, read the document's reference key to learn what to look for, detect every instance on each page with a spatial vision model, measure each one (OpenCV contour/skeleton tracing, with an LLM agent fallback), and hand off structured results. What I need help with: - Improving detection accuracy and recall on dense, messy,...

    I need a seasoned QA specialist to put my web application through its paces, concentrating on two core areas: overall functionality and the user interface. All testing must be carried out in Google Chrome, as that is where the bulk of my users will interact with the product. If you spot issues that only appear in other browsers, you’re free to note them, but Chrome is the primary focus. The job covers everything from validating key user flows and edge-case scenarios to making sure the layout, styling, and on-screen messages look and behave exactly as intended. I will provide access credentials, a short onboarding guide, and any additional assets you might need. Deliverables I expect: • A concise test plan outlining the scenarios you covered • A detailed bug report (in...

    We release new builds of my web application every 2 weeks and need each one put through thorough functional tests. Every cycle I want the core user flows validated on both desktop and mobile browsers, running on Windows, macOS, and Linux. The work is continuous: as soon as a build is ready I will share release notes and credentials, and you begin testing right away, logging anything that breaks expected behaviour. BrowserStack, Playwright, Selenium, or any comparable tool is fine—as long as the results are reliable, reproducible, and delivered quickly. Please keep a concise record for every issue you find: • clear steps to reproduce • actual vs. expected result • screenshots or screen-capture video • environment details (OS, browser, device, build numbe...

    I need a detail-oriented tester who can move comfortably between hands-on manual checks, structured API exercises, and careful data entry while I finalise a USSD menu for release. The core goal is data accuracy: every figure pulled from, written to, or displayed by the system must be proven correct. Here is how the work breaks down. • Web and desktop builds of the product both require functional sweeps. You will follow existing user stories, expand on them where gaps appear, and record every deviation in a concise bug report. • Our REST endpoints need repeatable validation. Feel free to use Postman, JMeter, or another tool you prefer, but make sure assertions cover all status codes, payload structures, and edge-case parameters. • During each round of testing you will e...
