Computing resource coverage is disclosed. In an example, a computing resource (CR) pool includes a plurality of CR types hosted on a plurality of hosts, where the plurality of CR types are routinely updated. A test repository stores a plurality of test cases (TC). A processor is configured to execute a testing service to compile, from a plurality of test daemons, a CR manifest of the CR types included in the CR pool. A TC manifest is compiled, including CR types tested by the plurality of TCs. The CR types included in the CR manifest are compared with the CR types included in the TC manifest. A test coverage report of tested and untested CR types is generated. A TC is added to the test repository based on the test coverage report.
