Two-phase Model-based Testing

Most test automation tools just do test execution automation. Without test design involved in the whole test automation process, the test cases remain ad hoc and detect only simple bugs. This solution is just automation without real testing. In addition, test execution automation is very inefficient.

What Agile Testing (Actually) Is

So, now that the first installment of this two fold article has been published (hence you might have an idea of what Agile Testing is not in my opinion), I’ve started feeling the pressure to explain what Agile Testing actually means to me.

Considering Agile Principles from a different angle

In addition to the four values, the Agile Manifesto contains twelve principles that are used as guides for all methodologies included under the Agile movement, such as XP, Scrum, and Kanban.

Fluent Interface Design Pattern in Automation Testing

Recently, I was going through some of the design patterns in Java by reading the book Head First Design Patterns by Eric Freeman, Elisabeth Robson, Bert Bates, and Kathy Sierra.

Rebuild Confidence in Your Test Automation

These days, development teams depend heavily on feedback from automated tests to evaluate the quality of the system they are working on.

Automation Testing Tutorials

Learn to execute automation testing from scratch with LambdaTest Learning Hub. Right from setting up the prerequisites to run your first automation test, to following best practices and diving deeper into advanced test scenarios. LambdaTest Learning Hubs compile a list of step-by-step guides to help you be proficient with different test automation frameworks i.e. Selenium, Cypress, TestNG etc.
