Allow babel transpilation of test helper files.

[jamestalmage]

We are doing all this work to ensure babel does not leak into any file but the test file, but there is a downside for "helper" files, etc.

The other option would be to hook require and make them provide some sort of include / exclude glob.

[sindresorhus]

Why did you close?

[jamestalmage]

Didn't mean to.

[sindresorhus]

I'm open to it, as it would be very nice to be able to use ES2015 stuff in test helper files too. I think a whitelist would be better so we could still make use of the ES2015 import semantics.

[SamVerschueren]

Would be very nice indeed! Maybe use something like .es6.js as extension? This way you don't need to update the whitelist.

[jamestalmage]

Or just default the whitelist to include test/_*, since the underscore prefix is already set aside to denote helpers.

Or just everything in the test directory? Event test/fixtures/**?

[sindresorhus]

@jamestalmage I think defaulting the whitelist to test/_* is a good idea, not so sure about the whole test directory, though. I would definitely not want my fixtures implicitly transpiled.

[jamestalmage]

Thats my feeling as well.

[just-boris]

+1, I want this thing too. But why do you need all that stuff around require-from-string?

Why not just add babel hook using require("babel-core/register");?

[jamestalmage]

Because, one goal of this library is not to pollute any of your production code with babel transforms/polyfills (unless you specifically ask it to).

[just-boris]

But all my source code is written for babel too. Will there an option to transpile files from my src/ folder in addition to test/?

I actually want my source code (non-test) to be transpiled by babel as well..... i.e. I want to be able to import a module that is written in ES6 into my ava test module. Is there a suggested technique for this today? Or is this a pending enhancement?

[sindresorhus]

@sparty02 Pending enhancement. Definitely something we want to support, but haven't had the chance yet. See #111. Any thoughts there much appreciated.

[sparty02]

@sindresorhus ahh.... thanks for the reference to #111. I'll take a look!

Closing this issue as it's already implemented.
