A Comprehensive Guide On JUnit 5 Extensions

JUnit is one of the most popular unit testing frameworks in the Java ecosystem. The JUnit 5 version (also known as Jupiter) contains many exciting innovations, including support for new features in Java 8 and above. However, many developers still prefer to use the JUnit 4 framework since certain features like parallel execution with JUnit 5 are still in the experimental phase.

How to Position Your Team for Success in Estimation

Estimates are critical if you want to be successful with projects. If you begin with a bad estimating approach, the project will almost certainly fail. To produce a much more promising estimate, direct each estimation-process issue toward a repeatable standard process. A smart approach reduces the degree of uncertainty. When dealing with presales phases, having the most precise estimation findings can assist you to deal with the project plan. This also helps the process to function more successfully, especially when faced with tight schedules and the danger of deviation.

Assessing Risks in the Scrum Framework

Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).

Top 17 Resources To Learn Test Automation

Lack of training is something that creates a major roadblock for a tester. Often, testers working in an organization are all of a sudden forced to learn a new framework or an automation tool whenever a new project demands it. You may be overwhelmed on how to learn test automation, where to start from and how to master test automation for web applications, and mobile applications on a new technology so soon.

How To Handle Multiple Windows In Selenium Python

Automating testing is a crucial step in the development pipeline of a software product. In an agile development environment, where there is continuous development, deployment, and maintenance of software products, automation testing ensures that the end software products delivered are error-free.
