    Auto Test File

    • Auto-generate test files in a watched directory for matching extensions.
    • Ask for test specs and insert into the generated test.
    • Generate test files based on default templates or define custom templates.

    Getting Started

    Installing

    • npm install auto-test-file
    • This will provide access to the atf command which can be used to start the file watcher.

    Setup

    • Add a watcher script to your package.json file, eg "atf": "atf -d 'src' -e 'ts' 'tsx'"
    • Add config settings either directly in the command line or using a config file. (See below.)
    • Use the default test file templates or replace with custom templates. (See below.)
    • Run the script, which will launch the watcher.
    • Files will be auto-generated while the script is running.
    • Index files and dot files are ignored.

    Using the config file

    auto-test-file can be configured either directly via the command line or using a config file. Settings passed into the command line will override config file settings.

    By default, auto-test-file will look for a file named atf.config.js in the root of the project directory. The path to the file can be changed using the --config option.

    Below is a sample config file:

    module.exports = {
      directory: "src",
      extensions: ["ts", "tsx"],
      noSpecInput: true
    };

    Using Custom Test File Templates

    • Test files are generated using two templates, the describeBlock and the specBlock template.
    • The default templates, found in /src/lib/templates, can be overridden by adding a corresponding template in the config file, eg
    module.exports = {
      directory: "src",
      extensions: ["ts", "tsx"],
      specTemplate: `
        test('<%= spec %>', () => {
           expect.hasAssertions();
        });
    `
    };
    • For templates to function, they must include the necessary properties. See the documentation in each template file for properties that are used.
    • Templates use Lodash Template - see their documentation for supported syntax.

    Config Options

    --config/ -c: point to a different config file than the default (atf.config.js) eg '/Users/bobsmith/my_project/foo.config.js'.

    --directory/ -d: name of directory to be watched eg 'src'.

    --extensions / -e: extensions for which to create test files eg 'js' 'jsx'.

    --noSpecInput: do not ask for specs on add of a file.

    describeTemplate: config file only. See "Using Custom Test File Templates".

    specTemplate: config file only. See "Using Custom Test File Templates".
