A library which provides some tools for testing Transformers.


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:

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


Please file feature requests and bugs at the issue tracker.



  • Fix strong mode errors.
  • Add missing dependency on package:stack_trace.


  • Bump maximum version allowed for code_transformers. The breaking change in version 0.5.0 has no impact here.


  • Widened type of phases parameter of testPhases function, which allows to use it to test aggregate transformers and transformer groups.


  • Changed all optional arguments to testPhases to named arguments.
  • Added skip and tags named arguments to testPhases, which will be forwarded on to the call to test.
  • messages optional argument to testPhases now accepts either Matchers or Strings.
  • Added expectBarbackErrors optional argument to testPhases.
