Although there are still many improvements going on, Puppeteer-Sharp is thread-safe. To improve loading performance, there are a few approaches you can take.
Launch one browser and then connect to it
You can launch one (real) browser and then use the ConnectAsync
method to connect to it.
await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
Headless = false,
});
var theBrowser1 = await Puppeteer.ConnectAsync(new ConnectOptions { BrowserWSEndpoint = browser.WebSocketEndpoint });
var theBrowser2 = await Puppeteer.ConnectAsync(new ConnectOptions { BrowserWSEndpoint = browser.WebSocketEndpoint });
var page1 = await theBrowser1.NewPageAsync();
var page2 = await theBrowser2.NewPageAsync();
await Task.WhenAll(
page1.GoToAsync("https://www.stackoverflow.com"),
page2.GoToAsync("https://serverfault.com/")
);
I know that code is not running in parallel, but you'll get the idea about reusing the same browser.
Create new pages on the same browser
If you are using TPL, you shouldn't have any issues creating new pages from different threads using the same browser.
await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
Headless = false,
});
var urls = new string[]
{
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com",
"https://www.stackoverflow.com"
};
await Task.WhenAll(
urls.Select(url => Task.Factory.StartNew(async () =>
{
var page = await browser.NewPageAsync();
return page.GoToAsync(url);
})));
Again, this example is just to give you an idea of how this could be accomplished.
Pages queue
There is one user who created a queue of X pages (for x from 0 to X => NewPage) and then he would grab pages from that queue. You can see the example here.
Check out the latest blogs from LambdaTest on this topic:
When working on web automation with Selenium, I encountered scenarios where I needed to refresh pages from time to time. When does this happen? One scenario is that I needed to refresh the page to check that the data I expected to see was still available even after refreshing. Another possibility is to clear form data without going through each input individually.
Xamarin is an open-source framework that offers cross-platform application development using the C# programming language. It helps to simplify your overall development and management of cross-platform software applications.
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?
When software developers took years to create and introduce new products to the market is long gone. Users (or consumers) today are more eager to use their favorite applications with the latest bells and whistles. However, users today don’t have the patience to work around bugs, errors, and design flaws. People have less self-control, and if your product or application doesn’t make life easier for users, they’ll leave for a better solution.
Agile software development stems from a philosophy that being agile means creating and responding to change swiftly. Agile means having the ability to adapt and respond to change without dissolving into chaos. Being Agile involves teamwork built on diverse capabilities, skills, and talents. Team members include both the business and software development sides working together to produce working software that meets or exceeds customer expectations continuously.
