How can I see long stack traces in my tests?

Question

When I run my test suite, failures will only include short stack traces.

bluebird supports generating long stack traces, but when I try to enable them, I suddenly get only the error message and no stack trace at all.

To see the full, long stack trace, you need to both enable long stack traces, as mentioned in the documentation and run mocha with --full-trace.

For example:

$ BLUEBIRD_DEBUG=1 mocha --full-trace
