Testing
Jest snapshot testing is simultaneously the most misused testing feature in the React ecosystem and genuinely useful when applied correctly. Teams either avoid it entirely (too fragile) or over-use it (snapshot everything and update blindly). Neither is right. This guide covers how snapshot testing actually works, when it provides real

Chromatic is a visual testing tool built specifically for Storybook. While Percy and Applitools operate at the page level (snapshot a URL), Chromatic operates at the component level — it captures every story in your Storybook and compares them against approved baselines. This makes Chromatic the right choice for design system

Applitools Eyes is a visual testing platform that uses AI to compare screenshots intelligently. Instead of pixel-by-pixel diffing (which generates noise from anti-aliasing and rendering differences), it uses a Visual AI model trained on millions of UI screenshots to distinguish real visual regressions from irrelevant rendering variations. This guide covers

SpecFlow is the .NET implementation of the Cucumber/Gherkin BDD framework. It integrates directly with MSTest, NUnit, and xUnit, making it a natural fit for .NET teams that want to practise behaviour-driven development without leaving the ecosystem. This guide covers everything from NuGet package installation through a working test suite

Testing REST APIs in Java has a reputation for being verbose. You set up an HTTP client, construct requests, execute them, parse the response, and then write assertions against the parsed data — often 20+ lines for a simple GET test. REST Assured changes this. It provides a fluent, BDD-style API
Testing
REST Assured's API was designed around the Given-When-Then structure from Behavior-Driven Development. This isn't just a cosmetic choice — tests written in BDD style are executable documentation. They describe what an API is supposed to do in terms that developers, QA engineers, and product managers can all
Testing
Postman and REST Assured are both popular tools for API testing, but they serve different needs and different teams. Choosing between them — or deciding to use both — requires understanding what each does well and where each falls short. Quick Overview Postman is a GUI-based API platform. You build requests visually,
Testing
Spring Boot and REST Assured are a natural combination. Spring Boot makes building REST APIs fast; REST Assured makes testing them readable. The combination gives you a complete Java API testing stack that covers everything from controller unit tests to full integration tests against a running server. This guide covers
Testing
Gherkin is the plain-language format that makes BDD tests readable by non-technical stakeholders. It looks deceptively simple — just English sentences with a few keywords — but writing good Gherkin is a skill. Poorly written feature files create tests that are brittle, hard to maintain, and misleading to read. This guide covers
Testing
While JUnit is the default choice for most Java testing, TestNG offers compelling features for API test suites specifically. Test groups, flexible data providers, built-in parallel execution, and dependency management between tests make TestNG well-suited for organizing large API test collections. This guide covers using REST Assured with TestNG effectively.
Testing
Cucumber is one of the most widely adopted BDD frameworks, and Java remains its most popular language host. The combination gives teams a way to write tests in plain English that non-technical stakeholders can read while developers implement real automated browser and API tests underneath. This guide walks you through

Behave is Python's most established BDD framework. It reads Gherkin .feature files, maps each step to a Python function, and executes them against your application. If you work in Python and want to practise behaviour-driven development, Behave is the natural starting point. This tutorial takes you from installation
