You can close the page using CloseAsync:
var page = browser.NewPageAsync();
////
await page.CloseAsync();
An using
block will also close the page:
using (var page = await new browser.PageAsync())
{
///
}
Puppeteer-Sharp v2.0.3+ also supports await using
blocks
await using (var page = await new browser.PageAsync())
{
///
}

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.
Hola Testers! Hope you all had a great Thanksgiving weekend! To make this time more memorable, we at LambdaTest have something to offer you as a token of appreciation.
The rapid shift in the use of technology has impacted testing and quality assurance significantly, especially around the cloud adoption of agile development methodologies. With this, the increasing importance of quality and automation testing has risen enough to deliver quality work.
ChatGPT broke all Internet records by going viral in the first week of its launch. A million users in 5 days are unprecedented. A conversational AI that can answer natural language-based questions and create poems, write movie scripts, write social media posts, write descriptive essays, and do tons of amazing things. Our first thought when we got access to the platform was how to use this amazing platform to make the lives of web and mobile app testers easier. And most importantly, how we can use ChatGPT for automated testing.
There are times when developers get stuck with a problem that has to do with version changes. Trying to run the code or test without upgrading the package can result in unexpected errors.
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.
