Running a simple Dart test in WebStorm 10.0.4

This should be trivial but it is not working as I think it should. I am new to WebStorm.

I have a simple test taken from Dart's new test offering at https://pub.dartlang.org/packages/test

.dart

import "package:test/test.dart";

void main() {
  test("String.split() splits the string on the delimiter", () {
    var string = "foo,bar,baz";
    expect(string.split(","), equals(["foo", "bar", "baz"]));
  });

  test("String.trim() removes surrounding whitespace", () {
    var string = "  foo ";
    expect(string.trim(), equals("foo"));
  });
}

Running this simple test gives the following exception:

J:\dart\dart-sdk\bin\dart.exe --ignore-unrecognized-flags --checked --package-root=J:\workspace\epimss\dart\epimss_shared\packages --enable-vm-service:60110 --trace_service_pause_events C:\Users\st.clair.clarke\AppData\Local\Temp\jetbrains_unit_config.dart

#3      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:148)

Process finished with exit code 255

The problem seems to be the line unittestConfiguration = config; in the jetbrains configuration - something is expected for the config.

Any help is appreciated.

Solution

According to this issue, test package is not yet supported by WebStorm's testing framework.

You have two ways right now:

Run it as usual dart application, not as a test
Use deprecated unittest package instead of test until issue is resolved.
