Mouse

The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport.

tip

If you want to debug where the mouse moved, you can use the Trace viewer or Playwright Inspector. A red dot showing the location of the mouse will be shown for every mouse action.

Every page object has its own Mouse, accessible with Page.Mouse.

await Page.Mouse.MoveAsync(0, 0);
await Page.Mouse.DownAsync();
await Page.Mouse.MoveAsync(0, 100);
await Page.Mouse.MoveAsync(100, 100);
await Page.Mouse.MoveAsync(100, 0);
await Page.Mouse.MoveAsync(0, 0);
await Page.Mouse.UpAsync();
