test-fixture NPM version Build Status Dependency Status

Copy test-fixtures to temp dir and get resolved file paths.

Why?

I am tired of writing

  • path.resolve(__dirname, 'test', 'fixtures'),
  • tmp.dir(callback),
  • fse.copy(fixtures, dir)
  • path.join(fixtures, 'file-a.js')

EVERY DAY!

So, I got this.

Install

$ npm install test-fixture --save

Usage

var fixtures = require('test-fixture');
var f = fixtures(); // by default, it will use 'test/fixtures' dir.

// copy 'test/fixtures' to the temp dir
f.copy(function(err, dir){
  f.resolve('a.js'); // '/<temp>/a.js'
});

fixtures([path…])

arguments base(dir of test fixtures)
undefined test/fixtures
'a' test/fixtures/a
'a', 'b' test/fixtures/a/b
'/path/to'(absolute) /path/to
'/path/to'(absolute), 'a' /path/to/a

Actually, the base is path.resolve('text/fixtures', path...)

.copy([to], callback)

  • to path= the destination folder where the test fixtures will be copied to. If not specified, fixtures will create a temporary dir.
  • callback function(err, dir)
  • err Error
  • dir path the destination directory for testing

Copy the test fixtures into a temporary directory.

.resolve([path…])

Resolves the paths to get the path of the test fixtures

After .copy()ed, it will resolve paths based on the destination dir.

If not, it will use the base dir. But never use both of them simultaneously.

/path/to/<base>
             |-- a.js
/path/to/<to>
           |-- a.js

Without copying

var f = fixtures(base);
f.resolve('a.js'); // -> /path/to/<base>/a.js

Using .copy()

var f = fixtures(base);
f.copy(to, function(err, dir){
  if (err) {
    return;
  }
  f.resolve('a.js'); // -> /path/to/<to>/a.js
});

For Implementors

fixtures.Fixtures(args)

  • args Arguments|Array paths to join

Override: ._root()

Returns path the base root. By default, it will returns ‘test/fixtures’, but you can override this method to specify it by your own.
