PuppeteerSharp.Contrib.Should is a should assertion library for the Puppeteer Sharp API.


Should assertions for IPage

  • ShouldHaveContentAsync
  • ShouldHaveTitleAsync
  • ShouldHaveUrlAsync
  • ShouldNotHaveContentAsync
  • ShouldNotHaveTitleAsync
  • ShouldNotHaveUrlAsync

Should assertions for IResponse

  • ShouldBeRedirection
  • ShouldBeSuccessful
  • ShouldHaveClientError
  • ShouldHaveError
  • ShouldHaveServerError
  • ShouldHaveStatusCode
  • ShouldHaveUrl
  • ShouldNotHaveStatusCode
  • ShouldNotHaveUrl

Should assertions for IElementHandle

  • ShouldBeCheckedAsync
  • ShouldBeDisabledAsync
  • ShouldBeEmptyAsync
  • ShouldBeEnabledAsync
  • ShouldBeHiddenAsync
  • ShouldBeReadOnlyAsync
  • ShouldBeRequiredAsync
  • ShouldBeSelectedAsync
  • ShouldBeVisibleAsync
  • ShouldExist
  • ShouldHaveAttributeAsync
  • ShouldHaveAttributeValueAsync
  • ShouldHaveClassAsync
  • ShouldHaveContentAsync
  • ShouldHaveFocusAsync
  • ShouldHaveValueAsync
  • ShouldNotBeCheckedAsync
  • ShouldNotBeEmptyAsync
  • ShouldNotBeReadOnlyAsync
  • ShouldNotBeRequiredAsync
  • ShouldNotBeSelectedAsync
  • ShouldNotExist
  • ShouldNotHaveAttributeAsync

The following failing examples will throw an exception with a message explaining why the assertion failed.

await Page.SetContentAsync(@"
   <div id='foo'>Foo</div>

var div = await Page.QuerySelectorAsync("#foo");
await div.ShouldHaveContentAsync("Bar");

Expected element to have content "Bar", but it did not.

await Page.SetContentAsync(@"
    <input id='foo' value='Foo' />

var input = await Page.QuerySelectorAsync("#foo");
await input.ShouldHaveValueAsync("Bar", "that would be the perfect example");

Expected element to have value "Bar" because that would be the perfect example, but found "Foo".

Package Description


Contributions to the Headless Chrome .NET API 🌐🧪 ✔️ PuppeteerSharp.Contrib.Should.Unsafe is a should assertion library for the Puppeteer Sharp API. ✔️ It provides a convenient way to write readable and robust browser tests in .NET 📄 https://hlaueriksson.me/PuppeteerSharp.Contrib.Should.Unsafe/ ⚠️ These extension methods are the sync over async versions of the originals from the PuppeteerSharp.Contrib.Should package. They may be convenient, but can be considered unsafe since you run the risk of a deadlock. ✔️ Works with: ◼️ Machine.Specifications ◼️ SpecFlow.xUnit ◼️ xunit
