Webinar: Building Selenium Automation Framework [Voices of Community]

Even though several frameworks are available in the market for automation testing, Selenium is one of the most renowned open-source frameworks used by experts due to its numerous features and benefits.

Continuous Integration explained with jenkins deployment

Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.

A Reconsideration of Software Testing Metrics

There is just one area where each member of the software testing community has a distinct point of view! Metrics! This contentious issue sparks intense disputes, and most conversations finish with no definitive conclusion. It covers a wide range of topics: How can testing efforts be measured? What is the most effective technique to assess effectiveness? Which of the many components should be quantified? How can we measure the quality of our testing performance, among other things?
