Currently it looks like CircleCI only builds the head of a branch for a pull request. I’d like to make sure every commit passes CI (I check commit message formatting, for example). Is there a way to make Circle build every commit instead of just building the branch’s head?

Here’s what it currently looks like:

But I’d like both commits to be built (which would result in a red X next to each of them).

Did you found a way to do this? I’m stuck in the same situation.  
Using the [“Trigger a new Build with a Branch”](https://circleci.com/docs/api/#new-build-branch) API, I specify the PR and a few things that seemed useful :

```auto
{
	"revision": "955bee65dfb7c8a4df40354c145fa32d40aef7e9",
	"build_parameters": {
		"CIRCLE_BRANCH": "pull/665",
		"CIRCLE_PR_NUMBER": "665",
		"CIRCLE_PR_USERNAME": "winzou",
		"CI_PULL_REQUEST": "https://github.com/villafinder/kaya/pull/665"
	}
}

```

But I still get an error : `fatal: Could not parse object '955bee65dfb7c8a4df40354c145fa32d40aef7e9'.` …
