設定 a custom timeout​

您可以為斷言指定自訂的超時時間，無論是全域還是每個斷言。預設的超時時間為 5 秒。

全域 timeout​

UnitTest1.cs
using Microsoft.Playwright;
using Microsoft.Playwright.MSTest;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace PlaywrightTests;

[TestClass]
public class UnitTest1 : PageTest
{
    [ClassInitialize]
    public static void GlobalSetup(TestContext context)
    {
        SetDefaultExpectTimeout(10_000);
    }
    // ...
}

每個斷言超時​

UnitTest1.cs
await Expect(Page.GetByText("Name")).ToBeVisibleAsync(new() { Timeout = 10_000 });
