Debugging

Debug logs show whether Global Cache computes, reuses, persists, or removes a value. Enable all Global Cache debug namespaces when running Playwright:

DEBUG=global-cache* npx playwright test

Or set it before Playwright loads the configuration:

playwright.config.ts

process.env.DEBUG = 'global-cache*';

The output also includes the address of the small local cache server. For example:

global-cache Starting server...
global-cache Starting server: done http://localhost:50138
global-cache:auth-state Fetching value...
global-cache:auth-state Computed: {"cookies":[...]}
global-cache:auth-state Saving value for 1h...
global-cache:auth-state Fetching value...
global-cache:auth-state cache-hit: {"cookies":[...]}

Limit logging to one key by using its namespace:

DEBUG=global-cache:auth-state npx playwright test

Run-scoped values are refreshed between executions in command-line, UI, and VS Code modes. Values with a TTL may be reused across executions until they expire or are explicitly deleted.
