testing package is used in non-tests code

[gm42]

Is this a support request?
No

Describe the bug
The LaunchDarkly Go SDK depends on testing package; this increases the size of release binaries and will create issues when accessing the command-line flags because they will be parsed by the testing package global init() first.

Hi @gm42, thanks for the report. I agree this isn't optimal.

Filed internally as 216653.

Any news on this? It's the only dependency we have which links testing

Sorry - no updates. It is on our backlog.
