transformer_test

A library which provides some tools for testing Transformers.

Features

This library provides a top level function testPhases which given a nested list of transformers to run and a list of inputs, will verify a list of expected outputs.

For example, given a transformer which copies all files to corresponding *.copy files, you could write the following test:

testPhases(
  [[new CopyTransformer()]],
  {
    'a|lib/a.dart': 'hello!'
  }, {
    'a|lib/a.dart': 'hello!'
    'a|lib/a.dart.copy': 'hello!'
  });
