As AI accelerates how software is built, Virtuoso QA helps organisations release with confidence through governed, agentic automation for functional, regression and end-to-end testing across any browser-based application, from Dynamics 365, Salesforce and SAP to Guidewire and custom-built systems. Virtuoso QA turns requirements, designs, live applications or existing suites into executable journeys. Through Touchstone, its agentic layer, brings in 30+ specialised agents to do the work, grounded in your sources and standards. The Analyst turns documentation into source-cited test requirements, the Architect designs the journeys that prove them, and Autopilot builds each one. Your team reviews and approves each stage, so nothing enters the suite on trust. Tests run on a deterministic engine within existing CI/CD pipelines, and self-healing fixes are proposed as reviewable diffs, keeping test suites current without manual rework. Every release is backed by evidence of what was tested, what changed and who approved it. That is why organisations in financial services, insurance, healthcare and the public sector trust Virtuoso QA where releases carry consequences. 131 Ratings Visit Website Checksum.ai Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence. 2 Ratings Visit Website MuukTest Are bugs slipping through your QA process and frustrating your customers?

Unlike traditional vulnerability tools that focus on application layers, z/Assure VAP conducts thorough and precise binary code scanning at the OS level to detect zero-day and integrity-based vulnerabilities without relying on signature files, using an Interactive Application Security Testing (IAST)-style approach to pinpoint real weaknesses and guide developers to the exact code requiring remediation. It generates detailed vulnerability disclosure reports that provide actionable insights and clear paths to fix issues, enabling teams to prioritize risk, strengthen defenses, and make mainframe vulnerability management a repeatable part of IT security and compliance programs. 1 Rating Visit Website
About The main goal for Karma is to bring a productive testing environment to developers. The environment being one where they don't have to set up loads of configurations, but rather a place where developers can just write the code and get instant feedback from their tests. Because getting quick feedback is what makes you productive and creative. Test your code on real browsers and real devices such as phones, tablets or on a headless PhantomJS instance. Control the whole workflow from the command line or your IDE - just save a file and Karma will run all the tests. Karma also watches all the files, specified within the configuration file, and whenever any file changes, it triggers the test run by sending a signal to the testing server to inform all of the captured browsers to run the test code again. Each browser then loads the source files inside an IFrame, executes the tests and reports the results back to the server.	About Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. By adding an argument (usually named done) to it() to a test callback, Mocha will know that it should wait for this function to be called to complete the test. This callback accepts both an Error instance (or subclass thereof) or a falsy value; anything else is invalid usage and throws an error (usually causing a failed test). These reporters expect Mocha to know how many tests it plans to run before execution. This information is unavailable in parallel mode, as test files are loaded only when they are about to be run. In serial mode, tests results will “stream” as they occur. In parallel mode, reporter output is buffered; reporting will occur after each file is completed. In practice, the reporter output will appear in “chunks” (but will otherwise be identical). If a test file is particularly slow, there may be a significant pause while it’s running.
