LGTM Really happy to see these improvements, looks much cleaner than what we had. |

Shouldn't there be a common.mustCall here?

LGTM with some nits. Maybe you can mention in the commit log that you also replace a few 'unexpected call' handlers with common.fail. Otherwise a nice cleanup. |

Can't this be a problem if data is emitted multiple times?

Yes. It was in the CI run actually. I'm going to fix it up when I push some changes.

Many of the tests use variables to track when callback functions are invoked or events are emitted. These variables are then asserted on process exit. This commit replaces this pattern in straightforward cases with common.mustCall(). This makes the tests easier to reason about, leads to a net reduction in lines of code, and uncovered a few bugs in tests. This commit also replaces some callbacks that should never be called with common.fail().

@cjihrig any chance you would be interested in sending a backport PR to v6.x? This isn't landing cleanly. Thanks! |

@cjihrig this is definitely not landing cleanly on v4.x. Adding the don't land label, please feel free to backport if you like |

Description of change
Many of the tests use variables to track when callback functions are invoked or events are emitted. These variables are then asserted on process exit. This commit replaces this pattern in straightforward cases with
common.mustCall(). This makes the tests easier to reason about, leads to a net reduction in lines of code, and uncovered a few bugs in tests.
