Summary

  • Adds device.setGeolocation({ latitude, longitude }), mirroring Playwright's setGeolocation API
  • Passing null or calling with no arguments clears the override
  • Validates latitude (-90..90) and longitude (-180..180) before calling the driver
  • Both drivers map to the device.location.set / device.location.clear RPC methods (mobilecli 1.0.7+)
  • Reported as a device.setGeolocation() test step

Test plan

  • Unit tests: coordinates forwarded to driver, null/undefined clears, out-of-range values throw, step title recorded
  • npm run build and full test suite pass (602 tests)

Walkthrough

The protocol adds a Geolocation type and setGeolocation session method. Device.setGeolocation validates coordinate bounds, clears the override for null or omitted input, and reports the operation as a step. MobilecliDriver and MobileNextDriver route updates to location RPCs. Tests cover forwarding, clearing, validation, step reporting, and updated mock driver contracts.

Merge Risk: โšช Minimal ยท up to 76631

This change adds a localized geolocation override API with validation and clear behavior; no actionable merge-blocking risk remains after normal checks and review.

๐ŸŒ Web query:

In ECMAScript, what is the result of NaN < -90, NaN > 90, and Number.isFinite(NaN)?

๐Ÿ’ก Result:

In ECMAScript, the result of NaN < NaN > 90 is false, and the result of Number.isFinite(NaN) is false [1][2][3][4]. Explanation: 1. NaN < NaN > 90: ECMAScript evaluates this expression from left to right [4]. First, NaN < NaN is evaluated. According to the Abstract Relational Comparison algorithm in the ECMAScript specification, if either operand is NaN, the comparison returns undefined [5]. However, the relational operators (<, >, etc.) in JavaScript convert an undefined result from this abstract operation into false [6][7][4]. Therefore, NaN < NaN evaluates to false. The expression then becomes false > 90. The false value is coerced to the number 0 for the comparison, resulting in 0 > 90, which is false [1][8]. 2. Number.isFinite(NaN): The Number.isFinite() method returns true only if the provided value is a number type and is a finite number (i.e., not Infinity, -Infinity, or NaN) [9]. Since the input is NaN, the method returns false [2][9].

Reject NaN coordinates.

Device.setGeolocation() forwards geolocation to this.driver.setGeolocation() after these checks. Because comparisons with NaN return false, NaN can bypass both range checks. Add Number.isFinite() checks and NaN test cases.

๐ŸŒ Web query:

site:playwright.dev/docs/api/class-browsercontext setGeolocation accuracy optional non-negative

๐Ÿ’ก Result:

In the Playwright API, the setGeolocation method accepts an optional, non-negative accuracy parameter [1]. When using this method, the accuracy is provided as part of a geolocation object, where it defines the accuracy of the location in meters [1]. If not specified, this value defaults to 0 [1]. The method is defined as follows: await browserContext.setGeolocation({ latitude: 59.95, longitude: 30.31667, accuracy: 100 }); As noted in the official documentation, the latitude must be between -90 and 90, and the longitude must be between -180 and 180 [1]. Passing null or undefined to setGeolocation emulates a position unavailable state [1].

Preserve Playwright accuracy or document the deviation

If Device.setGeolocation must match Playwrightโ€™s BrowserContext.setGeolocation, add optional non-negative accuracy to Geolocation, validate it, and include it in both device.location.set payloads. The current type omits accuracy, and both drivers discard it. Otherwise, document that this API supports only latitude and longitude.
