[Feature]: Configure (Chromium) channel when using PageTest in NUnit

Your question

Hello,

I can specify BROWSER and HEADED through the means of environment variables, to be used with a PageTest base class in my code. I've looked through the playwright sources, and was unable to find an environment variable for a Chromium channel. Is it possible to somehow control it in this scenario (for example, by setting some property, etc.)?

No, unfortunately this isn't possible at the moment. I'll convert this into a feature request though, and we can explore adding it.

I have the same question and request. Playwright supports browser_channel environment variable for Python, Java, JS/TS. I am not seeing it working in dotnet. I am struggling to figure out how to run Github Actions for Chrome and MSEdge.

As a workaround, you can manually instantiate the browser instance, obviously, for example, by doing:

 public class ChannelTest : PlaywrightTest
{
    private IBrowser browser;

    [SetUp]
    public async Task SetUp()
    {
        browser = await Playwright.Chromium.LaunchAsync(new()
        {
            Headless = false,
            Channel = "chrome-dev"
        });
    }

    [Test]
    public async Task ShouldUseChannel() {
        var page = await browser.NewPageAsync();
        var res = await page.GotoAsync("https://www.microsoft.com");
        Assert.IsTrue(res.Status == 200);
    }
}

You just have to understand the drawbacks in this approach, which is that a new Browser will be spun up depending on your parallelization settings. By default, we have the following in our tests:

[assembly: NUnit.Framework.Parallelizable(NUnit.Framework.ParallelScope.Fixtures)]

You need to adapt the above to the scope you've chosen & use the appropriate setup methods.
