The `NewHeartbeat` test checks if the `NewHeartbeat` function correctly initializes a new heartbeat with the given name, service type, and interval. It also verifies the initial status and info of the heartbeat.

The `Info()` method in the `Heartbeat` interface was not thread-safe,
which could lead to a race condition when accessing the `info` field.
To fix this issue, a mutex was added to protect the access to `info`
and ensure thread safety. The `Info()` method now locks the mutex
before accessing `info` and unlocks it before returning the value.
Additionally, a new `Close()` method was added to stop the heartbeat
ticker when it is no longer needed.
