Resolve source code for testing

Using resolveAsset and resolveSource, you can resolve Dart source code into a static element model, suitable for probing and using within tests of code you might have written for a Builder:

test('should resolve a simple dart file', () async {
  var resolver = await resolveSource(r'''
    library example;

    class Foo {}
  ''');
  var libExample = resolver.getLibraryByName('example');
  expect(libExample.getType('Foo'), isNotNull);
});

Run a Builder within a test environment

Using testBuilder, you can run a functional test of a Builder, including feeding specific assets, and more. It automatically creates an in-memory representation of various utility classes.
