Best API Security Testing Tools in 2026: Top 6 Compared

You need API security testing tools because functional tests check valid requests, while attackers send the requests your API should reject. ZAP, Burp Suite, 42Crunch, Schemathesis, Postman and Explorbot test these requests in different ways. According to Gartner, an average API breach leaks at least 10 times more data than an average security breach. You […]

AI Test Case Generation: A Practical Guide for QA Teams

Your team gets a new batch of user stories every sprint, and the request for test cases arrives before the stories are final. You write the cases by hand, and half of your week goes to formatting steps and expected results. Capgemini’s World Quality Report found that 89% of organizations pilot or deploy Gen AI […]

Deterministic AI Decisions: Why Explorbot Added Jev

Most AI models are built to write an answer. Jev is built to make a decision. Explorbot is an open-source agent that tests web applications in a real browser. It runs as fast as it can using small and cheap models. During a test, it often needs to answer small, closed questions: Which of these […]

Unit Testing vs Integration Testing: Key Differences and When to Use Each

Your team runs unit tests on every commit, and coding agents now write many of them: Capgemini’s recent World Quality Report finds that 43% of organizations experiment with generative AI in QA. But a green unit suite gives you only part of the proof. A renamed field in the payment service gets a green result […]

Performance Engineering Testing: Complete Guide & CI/CD Integration

Many QA teams run performance engineering testing as a single load test before a release. The test passes in staging, and the results stay in the load testing tool. But the release team checks a different dashboard. According to the Capgemini report, 94% of organizations review production data, and nearly half find it hard to […]

What Is Reliability Testing: Types, Metrics and Examples

Your team runs the regression suite every night, and the same build passes on Monday and fails on Wednesday. Now you need to decide if the product is unreliable or if the tests are. According to the Uptime Institute Annual Outage Analysis 2026, 57% of operators said their most recent major outage cost more than […]

Mercury Testing: Running the Mercury 2.5 Diffusion LLM as Explorbot’s Planner

Explorbot is an open-source QA agent for autonomous testing of web applications. You point it at a URL. It reads the page, works out what the application does, proposes test scenarios, and runs them in a real browser. When something breaks, it reports the problem with steps to reproduce, and every verified scenario can become […]

Manual Testing vs Automation Testing: Pros, Cons, and Key Differences

Your team already runs automated checks in CI and manual checks before each release. The World Quality Report 2025-26 by Capgemini shows a similar balance across the industry: teams automate 33% of their test cases on average, and manual checks cover the rest. So the real manual testing vs automation testing question is different: which […]

Mobile app testing usually starts on an emulator. Your team runs the suite and releases once CI passes. But a crash report arrives from a Galaxy S25 during checkout. It happened on a build that passed everything. According to AppsFlyer’s 2025 app uninstall benchmarks report, the global average 30-day uninstall rate reached 46.1% in 2024. […]

Manual Test Cases in the Agentic Era: The Baseline AI Agents Need

AI agents are changing the economics of software development. Source code can now be generated, refactored, and replaced faster than it can be reviewed. Automated tests are generated as side artifacts of the code production, which raises the question of testing AI-generated code before it reaches production. This acceleration is valuable. But it creates a […]

Usability Testing for Mobile Apps: A Complete Guide

When your team releases a mobile app, the automated test suite passes successfully. Every functional test completes and the release is on schedule. Passing tests proves the app works. Whether anyone can use it is a separate question. You can see the difference only when real users interact with the product. That’s the task of […]

Automated Cross-Browser Testing: Frameworks, Matrix & CI/CD Reporting

Every web product needs two things a browser can break: the layout your users see, and the JavaScript that makes it work. Your team releases features every week, and a rendering fault in Safari can reach a user before anyone on the team opens Safari. Automated cross browser testing finds those faults while the code […]

Your team releases an API to production every week. You run unit tests and review pull requests. The CI pipeline stays green. Here’s the catch: green checks alone leave a gap between what you test and what you promise your users. A strong API testing strategy closes that gap. In this guide, you’ll learn which […]

Every AI agent for test automation runs on a model. Your choice of model affects the quality of your tests and the price. If you choose the wrong model, you pay more for worse results. We tested four models in Explorbot’s most important slot. It is the part that plans the tests. In the end, […]
