+// This file is providing the test runner to use when running extension tests.
+// By default the test runner in use is Mocha based.
+//
+// You can provide your own test runner if you want to override it by exporting
+// a function run(testRoot: string, clb: (error:Error) => void) that the extension
+// host can call to run the tests. The test runner is expected to use console.log
+// to report the results back to the caller. When the tests are finished, return
+// a possible error to the callback or null if none.
