Playwright Assertions With Jev: Which Steps Can Be Tested by AI?

Your team writes Playwright tests every week. You add locators, you wait for text, you check that the button exists. But the next UI refactoring breaks half of those checks, and the feature works fine. The test fails for a reason unrelated to the product. In the article below, you’ll learn which part of an […]

Tester’s Army e2e Testing Framework: Reporting Steps and Artifacts

Tester’s Army e2e has made a loud entrance into test automation in October 2026. Its GitHub repository has passed 10,000 stars in two weeks. The appeal is easy to understand: write familiar TypeScript tests, then let an AI agent handle selected interactions. If you evaluate an e2e testing framework in 2026, reporting deserves a place […]

QA Strategy Guide: Components, Steps, Metrics and Template

Your team runs nightly automation and keeps 1,400 manual test cases in a spreadsheet. The question “are we ready to release?” takes a meeting to answer. The Stack Overflow Developer Survey found that 84% of developers use or plan to use AI tools, and 46% distrust the accuracy of the output. New tools arrive faster […]

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 […]

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. For teams that adopt agentic AI in software […]

Comparing Planning Models for an AI Agent for Test Automation: Qwen, Gemma, MiniMax and Luna

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, […]

Headless Browser Testing Guide: How to Speed Up Your CI/CD Workflows

Most CI pipelines don’t have a screen. Your tests need to run anyway. That’s the core case for headless browser testing: it lets you run a full browser in an environment that has no graphical interface. No display server, no GPU rendering, no window to pop up in the middle of your pipeline. The browser […]

Pairwise Testing in Software Testing: Cut Cases Without Cutting Corners

Testing every possible combination of inputs is theoretically the safest approach to software testing. It’s also practically impossible for anything beyond the simplest applications. Take a web form with five input parameters, each with four possible values. Exhaustive testing of all combinations requires 4^5 = 1,024 test cases. Add a sixth parameter and you’re at […]

Automated Exploratory Testing: How Explorbot Tests Your App on Its Own

For years, we treated automated tests as a regression safety net. That is what they are good at. The problem is simple: a test only walks the path you wrote for it. Hardcoded. Repeatable. Blind to anything outside the script. A test can pass on a screen where a real user is hopelessly lost, because […]

What makes Explorbot so fast

Explorbot is an open-source AI agent that explores web applications on its own. The first question people ask when they watch it run is always the same: how does it think so fast? They expect AI tools to be slow, hungry, and expensive. Explorbot is none of those things. The short answer is that Explorbot […]
