Access to Sibling element in Playwright

Using a selector that finds a list of locators in Playwright is exactly the same as calling .FindElements() in selenium, except that Playwright does not have a specifically named method like .FindLocators().

Playwright - a selector that matches multiple elements returns a list of locators, which you then iterate over:

var rows = page.GetByRole(AriaRole.Listitem);
var count = await rows.CountAsync();
for (int i = 0; i < count; ++i)
  Console.WriteLine(await rows.Nth(i).TextContentAsync());

Selenium - FindElements returns a list of elements that you have to iterate over.

IList < IWebElement > elements = driver.FindElements(By.TagName("p"));
foreach(IWebElement e in elements) {
  System.Console.WriteLine(e.Text);
}

With Visual Studio projects you can add post-build-events, which will run on you dev machine and in the Azure Pipeline during a build (tested with VSBuild@1)

Example using the VS UI: (you will need to adjust paths for ubuntu)

echo $(TargetDir).playwright\node\win32_x64\playwright.cmd install
$(TargetDir).playwright\node\win32_x64\playwright.cmd install
echo Done

or adding directly to a .csproj

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="echo $(TargetDir).playwright\node\win32_x64\playwright.cmd install;$(TargetDir).playwright\node\win32_x64\playwright.cmd install;echo Done" />
  </Target>

https://stackoverflow.com/questions/72866847/how-to-use-variables-in-selector-in-playwright-c

According to their documentation it should be possible. I see you are using StorageState maybe try StorageStatePath instead. Their example:

var context = await browser.NewContextAsync(new()
{
    StorageStatePath = "userCookies.json"
});

https://playwright.dev/dotnet/docs/auth

It's not clear from their documentation, and I never used this library before and could be wrong, but I believe StorageState expects the stringified JSON and not a file path. While StorageStatePath expects a file path / file name to the JSON and will read the file for you.

The author is available via:

var author = (string)TestContext.CurrentContext.Test.Properties.Get("Author");
