 ## Modify a test
 
 Now, let's modify the test. In your ChromeOS checkout, go to
-`src/platform/tast-tests/src/chromiumos/tast/local/bundles/cros/login` and open
+`src/platform/tast-tests/src/go.chromium.org/tast-tests/cros/local/bundles/cros/login` and open
 `chrome.go` (for convenience, there's also a `local_tests` symlink at the
 top of `tast-tests`). The `Chrome` function here will run directly on the
 test device.
