@kannappanr @harshavardhana can we close this issue?

[harshavardhana]

We can close as not reproducible anymore..

[harshavardhana]

Not reproducible will reopen if seen again.

[nitisht]

This issue can be observed again on minio/mint:latest image. @kannappanr

[kannappanr]

mocha version 4.0.1 seems to make the test hang. Modifying package.json to include mocha 3.5.0 instead of the latest which is 4.0.1

mocha version 4.0.1 seems to make the test hang. Modifying package.json to include mocha 3.5.0 instead of the latest which is 4.0.1

Is there a relevant bug upstream?

[kannappanr]

Found this behavior by accident. Just did more tests and found that it works till mocha 3.5.3. It fails on 4.0.0 (released 8 days ago) and 4.0.1 (released 5 days ago). Need to dig more, because this is a combination of minio-js and the recent mocha versions. I haven't looked into issues filed against mocha, if that is what you ask.

[kannappanr]

Found this in mocha's release note

Default Behavior

#2879: By default, Mocha will no longer force the process to exit once all tests complete. This means any test code (or code under test) which would normally prevent node from exiting will do so when run in Mocha. Supply the --exit flag to revert to pre-v4.0.0 behavior (@ScottFreeCode, @boneskull)

So, I am going to revert the change in the PR and add --exit flag to the script that runs the functional test.
