AVA can now load pre-compiled TypeScript files!

First, install the new @ava/typescript package:

npm install --save-dev @ava/typescript

Now let's assume your TypeScript files are in a src directory, output to a build directory. Configure AVA like so:

ava.config.js file:

export default {
  typescript: {
    rewritePaths: {
      'src/': 'build/'
    }
  }
}

Compile your TypeScript files and run your tests! Or, to run a specific test file, run npx ava src/test.ts.

For more examples see the @ava/typescript package.

As exciting as this is, it's still early days. We need your help improving our TypeScript support. Check out the open issues.

Experimental t.try() assertions

Thanks to the amazing work and patience of @qlonik we're shipping a new assertion! t.try() lets you perform assertions and decide whether to commit or discard their outcome. All kinds of interesting things can be built on top of this, from fuzzy testers to new test interfaces and more.

We're excited to get this out there, but it's not quite done yet. For now you have to opt in to this new feature. Being opt-in, we may make changes (breaking ones even!) until we feel this is stable.

To opt in, configure AVA with the following:

package.json:

{
  "ava": {
    "nonSemVerExperiments": {
      "tryAssertion": true
    }
  }
}

ava.config.js:

export default {
	nonSemVerExperiments: {
		tryAssertion: true
	}
};

We'd love to hear your feedback. Please join us in this issue: #2250

Also, if you're looking to help out with the remaining issues so that we can ship this without the opt-in, have a look at this project: https://github.com/orgs/avajs/projects/1

Thanks again @qlonik!

• We've added the common pitfall of sharing variables across asynchronous tests 49b202f
• We've updated the endpoint testing recipe to focus on the concept, not specific libraries 67e4dea

Thanks

Thank you @jeremenichelli, @jamesgeorge007, @dongjae93, @qlonik and @tryzniak. We couldn't have done this without you!

Greenkeeper has checked the engines key in any package.json file, the .nvmrc file, and the .travis.yml file, if present.

• engines was only updated if it defined a single version, not a range.
• .nvmrc was updated to Node.js 10
• .travis.yml was only changed if there was a root-level node_js that didn’t already include Node.js 10, such as node or lts/*. In this case, the new version was appended to the list. We didn’t touch job or matrix configurations because these tend to be quite specific and complex, and it’s difficult to infer what the intentions were.

For many simpler .travis.yml configurations, this PR should suffice as-is, but depending on what you’re doing it may require additional work or may not be applicable at all. We’re also aware that you may have good reasons to not update to Node.js 10, which is why this was sent as an issue and not a pull request. Feel free to delete it without comment, I’m a humble robot and won’t feel rejected 🤖
