Extends the illegal return type check for async functions to cover illegal return types for functions marked async* or sync* as well. Adds new error messages for illegal return types of functions marked async, async*, and sync*. These error messages conform with those produced by the analyzer. Closes https://github.com/dart-lang/sdk/issues/33068 Bug: www.dartbug.com/33068 Change-Id: I6d8690537139d3d094a4e295fcac9de4f4a7f0af Reviewed-on: https://dart-review.googlesource.com/69581 Commit-Queue: Daniel Hillerström <hillerstrom@google.com> Reviewed-by: Aske Simon Christensen <askesc@google.com>
Run Existing Tests ================== See the output of ../tools/test.py --help for how to run tests. See also https://code.google.com/p/dart/wiki/Building#Testing for detailed examples. Create New Tests ================ See comments above factory StandardTestSuite.forDirectory in ../tools/testing/dart/test_suite.dart for the default test directory layout. By default test-file names must end in "_test.dart", but some test suites, such as ./co19, subclass StandardTestSuite and override this default. See comments at the beginning of ../tools/testing/dart/multitest.dart for how to create tests that pass by failing with a known error. For example, ... int x = "not an int"; /// 01: static type warning ... as part of a test will only pass the "--compiler dart2analyzer" test if the assignment generates a static type warning.
