playwright geolocation not applied in test: how to fix

TL;DR

Set the geolocation coordinates and grant the geolocation permission when the browser context is created; granting permission after the page is open is too late. Both options belong in the same newContext call.

The query

playwright geolocation not applied in test: how to fix

Use this when

• the page ignores mocked coordinates
• a permission prompt appears despite grants
• location tests flake

Not for

• IP-based geolocation
• timezone mocking (a separate option)
• real-device GPS

Steps

1. Move geolocation into context creation: browser.newContext with geolocation coordinates and permissions ['geolocation'] together. Expected output: one newContext call carries both options.
2. Remove any later permission grants for geolocation in the test. Expected output: no grantPermissions call for geolocation after page creation.
3. Have the page query its geolocation and assert the returned coordinates. Expected output: the coordinates match what the context was given.
4. If tests share a context, give geolocation tests their own context so coordinates do not bleed across tests. Expected output: each geolocation test creates a fresh context.
5. Re-run and confirm the app behaves as if at the mocked location. Expected output: location-dependent UI shows the mocked area.
