  • The Current and Future State of Testing: a Conversation with Lisa Crispin

    Lisa Crispin talks about the current and future state of testing, how testing works in agile environments, the value testers bring to DevOps, testing machine learning and where testing is headed. Testing is a communication activity and communication skills are vital to successfully leveraging testing skills and knowledge in modern software development.

  • Unlocking Continuous Testing: The Four Best Practices Necessary for Success

    While the majority of organizations have enthusiastically embraced agile planning and development, most still find themselves unable to effectively implement continuous testing throughout the software development lifecycle. There are four best practices to help overcome this: focus on test quality, keep your tests short and atomic, test across multiple platforms, and leverage parallelization.

  • Java InfoQ Trends Report - July 2019

    The InfoQ Java trend report provides an overview of technology adoption and commentary on how we see the Java and JVM-related space evolving in 2019. Key developments include the release of Java 13, the rise of non-HotSpot JVMs and the evolution of GraalVM, and the changing landscape of Java microservice frameworks.

  • Test-Driven Development: Really, It’s a Design Technique

    Using a step-by-step example in Java, this article provides a practical example of how to use test-driven development (TDD) to divide, test, and conquer larger problems when coding.

  • Deep Dive into JUnit 5 Extension Model

    JUnit 5 is a modular and extensible testing framework with support for Java 8 and higher. The Jupiter extension model can be used to add custom features. This is explained by building out a simple set of extensions that support the BDD approach to testing with full code examples.

  • Architecturally Aligned Testing

    Testing microservices should not be done in a separate test phase, by a dedicated test team, but instead collaboratively by cross-functional teams. There is a shift left in testing to ensure that teams stay autonomous and a shift right in testing towards exploration and experimentation. Continuous Testing and a culture of experimentation are enablers to release microservices fast and reliably.

  • Automated Journey Testing with Cascade

    Starting with a brief history of software testing, we investigate Cascade, a new framework for testing “journeys”, eliminating overlapping coverage to produce fast unit tests.

  • Are Unit Tests Part of Your Team’s Performance Reviews?

    No matter how often you conduct performance reviews, there is no doubt unit testing should be one of the metrics measured. Eli Lopian explains what makes a good unit test and how to measure them to ensure your development team is truly agile.

  • How Java Developers Can Use the Wiremock Framework to Simulate HTTP-Based APIs

    A common syndrome in development shops today is the repeated creation of over-the-wire stubs and mocks for testing. In this article Wojciech Bulaty covers how Java developers can avoid reinventing the wheel and leverage Wiremock to build over-the-wire HTTP(s) stubs.

  • JUnit 5 - An Early Test Drive - Part 2

    JUnit, Java's most ubiquitous testing framework, is getting an update. In part one of our JUnit 5 coverage, we looked at how we got here and wrote some preliminary tests. In part two, we take a closer look at how to run tests and at some of the very cool new features JUnit 5 brings to the table for us developers.

  • JUnit 5 - An Early Test Drive - Part 1

    JUnit, Java's most ubiquitous testing framework, is getting an update. Yes, JUnit 5 is a complete rewrite that decouples "JUnit the Platform" from "JUnit the Tool" and makes the platform available to other testing frameworks, which might very well redefine the future of testing on the JVM. More than that, it evolves the API and has a very promising extension model.

  • Full Stack Testing: Balancing Unit and End-to-End Tests

    Full-stack testing can be a widespread and involved task. There are unit tests and end-to-end tests, but how do you know where to focus your efforts? In this article, David Copeland looks at the kinds of tests and how to balance the interplay between those tests and the overall software development effort.
