How to use LocatorAssertionsNotToBeEditableOptions class of Microsoft.Playwright package

So I resolved this with the following logic.

I created two variables:

1. List<string> downloadedFiles = new List<string>();
2. List<string> fileDownloadSession = new();

I then created a method to add as a handler to the page.Download that looks like this:

private async void downloadHandler(object sender, IDownload download)
{
    fileDownloadSession.Add("Downloading...");
    var waiter = await download.PathAsync();
    downloadedFiles.Add(waiter);
    fileDownloadSession.Remove(fileDownloadSession.First());
}

Afterwards, I created a public method to get the downloaded files that looks like this:

public List<string> GetDownloadedFiles()
{
    while (fileDownloadSession.Any())
    {
        
    }
    
    var downloadedFilesList = downloadedFiles;
    downloadedFiles = new List<string>();
    return downloadedFilesList;
}

All these methods and planning are in a separate class of their own so that they can monitor the downloaded files properly, and also to freeze the main thread so it can grab all of the required files.

All in all it seems just as sketchy of a solution, similarly to how you would implement it in Selenium, nothing much has changed in terms of junkyard implementations in the new frameworks.

You can find my custom class here: https://paste.mod.gg/rztmzncvtagi/0, enjoy, there is no other topic that answers this specific question for playwright on C#.

Code here, in case it gets deleted from paste.mod.gg:

You can use the selecting selectors based on layout for this.

await page.Locator("span:below(:text(\" Status :\"))").TextContentAsync()

LaunchAsync expects a BrowserTypeLaunchOptions class. You could have that object serialized in a JSON file, parse it and pass that options instance as an argument.

This should do it:

ILocator service17 = page.Locator("//span[text()=ServiceName" + ServiceName + "]");

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>

The solution I found to this was to simply remove the part of the test name in parenthesis, which caused the dotnet test command to run every test with a matching name. I then added a random guid to the name of each test trace that was generated in order to prevent them from overwriting eachother.

You can use the selecting selectors based on layout for this.

await page.Locator("span:below(:text(\" Status :\"))").TextContentAsync()

The author is available via:

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

If there are multiple Author attributes, this will retrieve the first one. If you want to see them all, use

var authors = (IList)TestContext.CurrentContext.Test.Properties["Author"];

This should do it:

ILocator service17 = page.Locator("//span[text()=ServiceName" + ServiceName + "]");
