Google Calendar API error : usage limits exceeded

Question

I'm working with google calendar API.

I'm getting error message :

Calendar usage limits exceeded

Error in details :

{
    "code":    403,
    "errors":  [{
        "domain":  "usageLimits",
        "message": "Calendar usage limits exceeded.",
        "reason":  "quotaExceeded"
    }],
    "message": "Calendar usage limits exceeded."
}

This happens anytime sometimes in just inserting 5 events or sometimes more than 25 and even I have used batch request for inserting events. Is there any way that is specially available for testing calendar API?

L'est see the Google documentation : support.google.com/a/answer/2905486?hl=fr or support.google.com/a/answer/2905486?hl=en Possible duplicate of Strange error 403: "Calendar usage limits exceeded" when adding event with attendee — Meloman

The original question asks "Is there any way that is specially available for testing calendar API?". This is really the core issue. There is a lack of transparency as to what causes this error to occur. I have read https://support.google.com/a/answer/2905486?hl=en, but none of those apply to my application. If I knew what is really causing this error, I might be able to avoid it.

I previously had a Google Calendar simulator for a lot of my testing but it became too arduous and was bypassing testing, so recently converted to using test accounts made of free gmail accounts to target insertions of test data and then read it out. I don't have to try very hard or do a lot of inserts to cause this error. I have implemented exponential backoff starting at 6 seconds; it allowed an insert at 25 minutes after initial failure. That was for a failure which occurred inserting a single event about two minutes later than the previous insert to the same account. The failing insert was the 9th insert of the same data into the same calendar over a period of almost 20 minutes, the 10th in 30 minutes. These are not large numbers in a test environment.

This is a serious impediment to testing. The only way I can see to work around this is to acquire a pool of gmail accounts and pull a new one from the pool when I wear one out. Not only is that more work and maintenance for me, it's bad for google too because of a bunch of accounts that don't map to real users.

If someone has a better idea I'm all ears. What I'd prefer is a way of opting in to testing on specific google accounts, meaning the user expressly asks for google to not be concerned with abuse (assuming that's the rationale for this error).
