Bump Microsoft.Playwright from 1.59.0 to 1.60.0

[dependabot]

Updated Microsoft.Playwright from 1.59.0 to 1.60.0.

Release notes

Sourced from Microsoft.Playwright's releases.

1.60.0

💬 Custom assertion messages

Expect() overloads now accept a custom message that is prepended to any failure, giving extra context in test reports:

await Expect(page.Locator("#status"), "Should be logged in").ToBeVisibleAsync();

When the assertion fails, the message is prefixed:

Should be logged in
Locator expected to be visible

🌐 HAR recording on Tracing

Tracing.StartHarAsync() / Tracing.StopHarAsync() expose HAR recording as a first-class tracing API, with the same Content, Mode and UrlFilter options as RecordHar:

await context.Tracing.StartHarAsync("trace.har");
var page = await context.NewPageAsync();
await page.GotoAsync("https://playwright.dev");
await context.Tracing.StopHarAsync();

🪝 Drop API

New Locator.DropAsync() simulates an external drag-and-drop of files or clipboard-like data onto an element. Playwright dispatches dragenter, dragover, and drop with a synthetic [DataTransfer] in the page context — works cross-browser and is great for testing upload zones:

await page.Locator("#dropzone").DropAsync(new() {
    Files = new FilePayload() {
        Name = "note.txt",
        MimeType = "text/plain",
        Buffer = Encoding.UTF8.GetBytes("hello"),
    },
});

await page.Locator("#dropzone").DropAsync(new() {
    Data = new Dictionary<string, string> {
        ["text/plain"] = "hello world",
        ["text/uri-list"] = "https://example.com",
    },
});

🎯 Aria snapshots

• Expect(page).ToMatchAriaSnapshotAsync() now works on a Page, in addition to a Locator — equivalent to asserting against Page.Locator("body").
• New Boxes option on Locator.AriaSnapshotAsync() / Page.AriaSnapshotAsync() appends each element's bounding box as [box=x,y,width,height], useful for AI consumption.
