How to verify whether email is received in google mail

Hi,

There is a challenge of mail notification issue which concerns me for a while, it' about automated verification of certain email in a google mail.

Until now i have mapped google mail obj and verified email via google mail gui, but this test is too depentent on google mail obj. when google mail gui changed, this test will stop working and obj needs to be updated.

Could somebody share the knowledge with me how to do this task in another way, e.g. verifying email in backend?

Thanks in advances,

Lee
