Aspects capture test coverage in a distributed system, wherein a processor instigates execution of a unique hypertext transfer request protocol test case within a distributed system of different, networked servers. The header of the unique test case includes a unique name for the unique test case, and the distributed system servers are each configured to, in response to processing a test case, generate a time-stamped log entry that includes header data for the processed test case and a uniform resource locator address of the processing server. The processor thus maps the unique test case to a subset of the distributed system servers as endpoint servers of the unique test case, in response to determining that the uniform resource locator addresses of each of the subset endpoint servers are listed within generated log entries of the endpoint servers in association with the unique test case name.
