# @ava/babel-preset-transform-test-files [![Build Status](https://travis-ci.org/avajs/babel-preset-transform-test-files.svg?branch=master)](https://travis-ci.org/avajs/babel-preset-transform-test-files) > [Babel] preset for use with [AVA] test files Currently contains: - [`babel-plugin-espower`](https://github.com/power-assert-js/babel-plugin-espower) and the patterns that should be enhanced - [`@ava/babel-plugin-throws-helper`](https://github.com/avajs/babel-plugin-throws-helper/) ## Install ```console $ npm install --save @ava/babel-preset-transform-test-files ``` ## Usage Add `@ava/transform-test-files` to your [Babel] presets. You can disable `babel-plugin-espower` by setting the `powerAssert` option to `false`: ```json { "presets": [ ["@ava/transform-test-files", {"powerAsssert": false}] ] } ``` Require `@ava/babel-preset-transform-test-files/package-hash` to get a combined hash for the installed version of the preset, as well as the plugins used.
