Version 1.20

Web-First Assertions

Playwright for .NET 1.20 introduces Web-First Assertions.

Consider the following example:

using System.Threading.Tasks;
using Microsoft.Playwright.NUnit;
using NUnit.Framework;

namespace Playwright.TestingHarnessTest.NUnit
{
    public class ExampleTests : PageTest
    {
        [Test]
        public async Task StatusBecomesSubmitted()
        {
            await Expect(Page.Locator(".status")).ToHaveTextAsync("Submitted");
        }
    }
}

Playwright will be re-testing the node with the selector .status until fetched Node has the "Submitted" text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached. You can pass this timeout as an option.

Version 1.17

Frame Locators

Playwright 1.17 introduces frame locators - a locator to the iframe on the page. Frame locators capture the logic sufficient to retrieve the iframe and then locate elements in that iframe. Frame locators are strict by default, will wait for iframe to appear and can be used in Web-First assertions.

Frame locators can be created with either [method: Page.frameLocator] or [method: Locator.frameLocator] method.

var locator = page.FrameLocator("#my-frame").Locator("text=Submit");
await locator.ClickAsync();

Read more at our documentation.

Trace Viewer Update

Playwright Trace Viewer is now available online at https://trace.playwright.dev! Just drag-and-drop your trace.zip file to inspect its contents.

Note

: trace files are not uploaded anywhere; trace.playwright.dev is a progressive web application that processes traces locally.

• Playwright Test traces now include sources by default (these could be turned off with tracing option)
• Trace Viewer now shows test name
• New trace metadata tab with browser details
• Snapshots now have URL bar

HTML Report Update

• HTML report now supports dynamic filtering
• Report is now a single static HTML file that could be sent by e-mail or as a slack attachment.

New APIs

• Page.RouteAsync() accepts new times option to specify how many times this route should be matched.
• Page.SetCheckedAsync(selector: string, checked: Boolean) and Locator.SetCheckedAsync(selector: string, checked: Boolean) was introduced to set the checked state of a checkbox.
• Request.SizesAsync() Returns resource size information for given http request.
• Tracing.StartChunkAsync() - Start a new trace chunk.

Important ⚠

• ⬆ .NET Core Apps 2.1 are no longer supported for our CLI tooling. As of August 31st, 2021, .NET Core 2.1 is no longer supported and will not receive any security updates. We've decided to move the CLI forward and require .NET Core 3.1 as a minimum.

Browser Versions

• Chromium 96.0.4641.0
• Mozilla Firefox 92.0
• WebKit 15.0

Version 1.14

⚡️ New "strict" mode

Selector ambiguity is a common problem in automation testing. "strict" mode ensures that your selector points to a single element and throws otherwise.

Set setStrict(true) in your action calls to opt in.

// This will throw if you have more than one button!
await page.ClickAsync("button", new Page.ClickOptions().setStrict(true));

📍 New Locators API

Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment.

The difference between the Locator and ElementHandle is that the latter points to a particular element, while Locator captures the logic of how to retrieve that element.

Also, locators are "strict" by default!

var locator = page.Locator("button");
await locator.ClickAsync();

Learn more in the documentation.

🧩 Experimental React and Vue selector engines

React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to attribute selectors and supports all attribute selector operators.

await page.ClickAsync("_react=SubmitButton[enabled=true]");
await page.ClickAsync("_vue=submit-button[enabled=true]");

Learn more in the react selectors documentation and the vue selectors documentation.

✨ New nth and visible selector engines

• nth selector engine is equivalent to the :nth-match pseudo class, but could be combined with other selector engines.
• visible selector engine is equivalent to the :visible pseudo class, but could be combined with other selector engines.

// select the first button among all buttons
await button.ClickAsync("button >> nth=0");
// or if you are using locators, you can use First, Nth() and Last
await page.Locator("button").First.ClickAsync();

// click a visible button
await button.ClickAsync("button >> visible=true");
