vinyl-fs-mock

A fake file system implementation, used for test code written based on vinyl and vinyl-fs. Useful for gulp plugin unit test. With vinyl-fs-mock, all the file fixtures can be provided inline. So not more external fixtures needed.

Install

$ npm install vinyl-fs-mock

          src:
            coffee:
              'sample.coffee': """
                console.log 'Hello world'
              """
              'another.coffee': """
                fib = (n) ->

    fs.src 'src/coffee/*.coffee'
      .pipe coffee
        bare: true
      .pipe fs.dest 'dest/js'
      .onFinished done, (folder) ->
        # console.log fs.directory  # Display whole tree of files
        folder.should.equal fs.openFolder('dest/js')                
        folder['sample.js'].should.not.be.null
