Cannot show descriptive assertion messages

[kazupon]

When i was using webpack-espower-loader in my environment (https://github.com/kazupon/vue-plugin-boilerplate), it's works.
However When the test was failed, power-assert cannot show the descriptive assertion messages.

Please see the detail error log (karma reporter: progress):
https://gist.github.com/kazupon/3ceabbe4cac1b703aa17

I become curious about the following warning messages has been output.

WARNING in ./~/power-assert/~/power-assert-formatter/lib/create.js
Critical dependencies:

What I'm doing wrong?

Thanks!

Hi @kazupon, thank you for reporting.

To write tests in ES6 with Babel, please use babel-plugin-espower or espower-babel (espower-babel uses babel-plugin-espower internally).

webpack-espower-loader (and the other instrumentors) transforms code after babel, which does not work since babel's output has changed.

babel-plugin-espower works as a babel plugin and runs before babel's transformation, so it works as expected.

FYI: I made a pull-req for you

Warning from webpack is due to the use of a dynamic require (which is inevitable hack for plugin system) and is not really an issue, just a warning. Please ignore it though you may feel uncomfortable with.

I confirmed that it works.

Thank you for reporting! 👍
Also noticed that this should be in power-assert FAQ.
