As seen in the "Rest API for Code Insight Code Coverage for BitBucket Server 7", Code coverage is not in Bitbucket Server 7.0 yet.

Code coverage has not been implemented as a core feature in Bitbucket Server yet.

It is also said here.

It's a bit different if you're using Bitbucket cloud or Bitbucket server.

On Bitbucket cloud, you need to:

• Use the local proxy in order to bypass authentication on the REST API.

• Change the url scheme from https to http.

• Set some parameters in the endpoint which you get from bitbucket default environments variables such as BITBUCKET_REPO_OWNER, BITBUCKET_REPO_SLUG and BITBUCKET_COMMIT.
