Some of the Auth Credentials needs to be populated for the ApiTests to work.

Please follow the following steps to populate the valid AuthCredentials
and copy it to AuthCredentials.h file

You will need to replace the following values:

$KGOOGLE_CLIENT_ID
Get the value of the CLIENT_ID key in the GoogleService-Info.plist file.

$KGOOGLE_TEST_ACCOUNT_REFRESH_TOKEN
GOOGLE_TEST_ACCOUNT_REFRESH_TOKEN is the Google SignIn refresh token obtained
for the Google client ID, saved for continuous tests. (Check out
generate_refresh_token.sh for instructions on how to create a refresh token.)

$KGOOGLE_USER_NAME
The name of the test user for Google SignIn. e.g. "Fname Lname"

$KFACEBOOK_APP_ID
FACEBOOK_APP_ID is the developer's Facebook app's ID, to be used to test the
'Signing in with Facebook' feature of Firebase Auth. Follow the instructions
on the Facebook developer site: https://developers.facebook.com/docs/apps/register
to obtain such an id.

$KFACEBOOK_APP_ACCESS_TOKEN
Once you have a Facebook App Id, click on settings->basic from the dashboard of
your app. You can see both your App ID and the App Secret. Once you have both
of these, generate the access token using the instructions from
https://developers.facebook.com/docs/facebook-login/access-tokens/#apptokens.

tl;dr (remove the whitespace):
  curl -X GET "https://graph.facebook.com/oauth/access_token
    ?client_id=your-app-id
    &client_secret=your-app-secret
    &grant_type=client_credentials"

$KFACEBOOK_USER_NAME
The name of the test user for Facebook Login. A test user with this name will
be created and deleted as part of these tests. e.g. "Fname Lname"

$KCUSTOM_AUTH_TOKEN_URL
A URL to return a Custom Auth token.

$KCUSTOM_AUTH_TOKEN_EXPIRED_URL
A URL to return an expired Custom Auth token.

$KCUSTOM_AUTH_USER_ID
The ID of the test user in the Custom Auth token.
