[Feature Request] Per-Worker Logger #1867
Description
Is your feature request related to a problem? Please describe.
When we run tests, we create a new Temporal Namespace for each test, and have that test's Worker connect to that namespace. This ensures tests can be run in parallel while being isolated from each other.
It also means we have a Worker per test. There are some things related to logs that we would like to be able to test, for example:
- Assert on log output
- Suppress Activity failure logs when they are expected
However, because the logger is configured by Runtime.install, which is global, it is not possible to have multiple Workers running in the same process using different logger instances so we can have per-test behaviour.
Describe the solution you'd like
Allow the Logger to be configured at the Worker level. This would allow us to create a "test logger" instance for each test to enable what we want.
