The sky’s the limit (and even beyond that) when you want to run test automation. Technology has developed so much that you can reduce time and stay more productive than you used to 10 years ago. You needn’t put up with the limitations brought to you by Selenium if that’s your go-to automation testing tool. Instead, you can pick from various test automation frameworks and tools to write effective test cases and run them successfully.
To decide what automation technology to use, we brought together Joe Colantonio, Founder of TestGuild, Sneha. V, Director of Quality Engineering, Everfi, and Carlos Kidman, Director of Engineering, Stealth Startup. The panel discussion was hosted by Mudit Singh, Marketing head at LambdaTest. Mudit decided to take a step backwards and let the panel discussion happen.
It’s essential to test all components of your website to see if they work as expected. Playwright’s end to end testing capability helps you achieve this easily. However, if you’re comfortable using Python, you can pair it with the Playwright testing framework to run Python end to end testing on your website.
JavaScript is one of the most widely used programming languages. This popularity invites a lot of JavaScript development and testing frameworks to ease the process of working with it. As a result, numerous JavaScript testing frameworks can be used to perform unit testing.
The speed at which tests are executed and the “dearth of smartness” in testing are the two major problems developers and testers encounter.
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.
