Refactors the existing test suite to use a `_Good`, `_Bad`, and `_Ugly` testing structure. This new format improves the clarity and organization of the tests by distinguishing between happy path scenarios (_Good), expected failures (_Bad), and edge cases (_Ugly).
In addition to reorganizing the existing tests, this change also introduces new `_Bad` test cases to `xmrig_test.go` to cover previously untested failure modes, such as a missing miner binary and an unreachable API. This improves the overall quality and robustness of the test suite.
Added tests for GetMiner and ListMiners in the manager, and for the GetInfo and Doctor endpoints in the service. This increases the overall test coverage of the pkg/mining package.
Added tests for StartMiner and StopMiner in the manager, increasing test coverage for the pkg/mining package.
Refactored the findMinerBinary function to fall back to the system PATH, making the application more robust and easier to test.
This commit introduces a number of new tests for the `pkg/mining` package,
increasing the overall test coverage from 8.2% to 40.7%.
The following changes were made:
- Added tests for the `XMRigMiner` struct, including its methods for
installation, starting, stopping, and getting stats.
- Added tests for the `Service` layer, including the API endpoints for
listing, starting, stopping, and getting stats for miners.
- Added tests for the `Manager`, including starting and stopping multiple
miners, collecting stats, and getting hashrate history.
- Introduced a `ManagerInterface` to decouple the `Service` layer from the
concrete `Manager` implementation, facilitating testing with mocks.
