Writing Tests with Playwright .NET

Writing tests with Playwright .NET allows developers to automate user interaction and control web application doings effectively. Key scene include:

Basic Test Structure

Playwright .NET tests are written as asynchronous methods in C #, apply the async and await keywords. A typical examination involves launching the browser, navigating to a web page, performing user-like interaction, and asserting expected outcome such as page titles or element visibility.

Using Locators

Playwright proffer a powerful Locator API that permit you find and interact with elements through CSS selectors, textbook, character, and other strategies. This ensures examination are more resilient to DOM changes and supports complex queries for honest element handling.

Assertions

Assertions in Playwright are create using the built-in Expect API, which includes automatic wait and retries until weather are met. This reduces flakey tests by ensuring elements are ready before verification, such as checking profile, textbook content, or page URL.

Handling Navigation and Pop-ups

Tests can handle page seafaring, iframe content, modal dialogs, and new browser check seamlessly, allowing model of complex user workflow.

Integration with Test Frameworks

Playwright integrates with MSTest, NUnit, and xUnit model, providing dimension like [Test], [SetUp], and [TearDown] to structure examination and lifecycle hooks, which help in preparing and pick up resource efficiently.

Example

[Fact]
public async Task BasicTest ()

{
await Page.GotoAsync (& # 8220; https: //playwright.dev & # 8221;);
await Expect (Page) .ToHaveTitleAsync (new Regex (& # 8220; Playwright & # 8221;));
await Page.GetByRole (AriaRole.Link, new () {Name = & # 8220; Get started & # 8221;}) .ClickAsync ();
await Expect (Page.GetByRole (AriaRole.Heading, new () {Name = & # 8220; Installation & # 8221;})) .ToBeVisibleAsync ();

}
