Testing
Cucumber is often pitched as "better JUnit" — more readable, closer to requirements, collaborative. That framing is wrong. Cucumber and JUnit aren't alternatives to each other; they serve different purposes and most teams need both. The real question isn't "Cucumber or JUnit?" It&
Testing
A Cucumber test suite with 200 scenarios running sequentially might take 10-15 minutes. That's too long for a feedback loop during development and an obstacle in CI pipelines. Parallel execution can cut that to 2-4 minutes, but it requires making your tests thread-safe. This guide
Testing
Three frameworks dominate the Java BDD landscape: Cucumber-JVM, JBehave, and Serenity BDD. All three let you write acceptance tests in a business-readable format and map them to Java glue code. Beyond that surface similarity, they make very different trade-offs. Picking the wrong one costs you months of
Redis
Redis Pub/Sub and Redis Streams are fundamentally different messaging primitives, and each requires distinct testing approaches. Pub/Sub is ephemeral—messages are lost if no subscriber is connected. Streams are persistent—messages are stored until explicitly deleted. This guide shows how to test both reliably. Redis Pub/Sub Testing
Testing
Cucumber-JVM brings Behaviour-Driven Development to the JVM. Combined with Spring Boot, it gives you executable specifications that run against a real (or sliced) application context. This guide covers everything from zero to a working BDD suite: dependency setup, Spring integration, writing your first feature file, defining steps, and
Testing
A Cucumber suite that takes 20 minutes to run is a suite developers skip. Parallel execution cuts that time proportionally to the number of available cores — a suite that ran sequentially in 20 minutes can finish in 4 minutes on a 6-core machine. But parallelism also exposes shared state
Redis
Testing code that depends on Redis presents a fundamental choice: simulate Redis in-process with a mock library, or spin up a real Redis instance via Testcontainers. Both approaches have distinct trade-offs that affect test speed, reliability, and the bugs you catch. This guide walks through both options in
Testing
Cucumber-JVM scenarios often span multiple step definition classes. A login step puts a session token somewhere. A checkout step needs that token. A verification step needs the order ID that checkout returned. Without a deliberate state-sharing strategy, you end up with static fields, thread-local hacks, or a
Testing
Behavior-Driven Development (BDD) is a way of writing tests that describes system behavior in plain language that both technical and non-technical team members can read and understand. Cucumber is the most widely-used tool for this in the Java ecosystem — it runs tests written in Gherkin syntax (Given/
Redis
Redis Cluster is the native horizontal scaling solution for Redis. It partitions data across multiple nodes using consistent hashing (16384 slots), with each node responsible for a subset. When a primary fails, a replica is promoted. This guide covers how to test cluster behavior—slot assignment, redirects, failover, and reconnection—
Testing
Red-teaming is not a new concept. Military planners have used adversarial war-gaming for decades. Security engineers have applied the same mindset to networks and applications. Now, as large language models move into production systems that handle sensitive decisions, the red-team discipline has migrated into AI — and it
Testing
Cucumber is easy to start with and surprisingly hard to do well. The gap between a Cucumber test suite that helps the team and one that becomes a maintenance burden comes down to a handful of decisions about how you write Gherkin and structure step definitions. This guide focuses on
