BrowserStack\LocalException : Key is required to start local testing

[nguyennguyen6bk]

I run phpunit test.php for my test and get the result:
PHP Fatal error: Uncaught BrowserStack\LocalException: [0]: Key is required to start local testing!
thrown in vendor/browserstack/browserstack-local/lib/Local.php on line 125
Who know the root cause. Please let me know.
Thanks!

Hey @nguyennguyen6bk

The error indicates that you have not specified the access key. Try exporting your access key under the environment variable:

$ export BROWSERSTACK_ACCESS_KEY=<your access key>

Once the key is added to the environment, try running the test.
