When I started writing tests with Cypress, I was always going to use the user interface to interact and change the application’s state when running tests.
I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives.There is also a lot of discussion about “agile”, much written about “agile”, and there are many presentations about “agile”. A question that is often asked is what comes after “agile”? Many testers work in “agile” teams so this question matters to us.
In today’s fast-paced world, the primary goal of every business is to release their application or websites to the end users as early as possible. As a result, businesses constantly search for ways to test, measure, and improve their products. With the increase in competition, faster time to market (TTM) has become vital for any business to survive in today’s market. However, one of the possible challenges many business teams face is the release cycle time, which usually gets extended for several reasons.
With new-age project development methodologies like Agile and DevOps slowly replacing the old-age waterfall model, the demand for testing is increasing in the industry. Testers are now working together with the developers and automation testing is vastly replacing manual testing in many ways. If you are new to the domain of automation testing, the organization that just hired you, will expect you to be fast, think out of the box, and able to detect bugs or deliver solutions which no one thought of. But with just basic knowledge of testing, how can you be that successful test automation engineer who is different from their predecessors? What are the skills to become a successful automation tester in 2019? Let’s find out.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
