4// This file is providing the test runner to use when running extension tests.
5// By default the test runner in use is Mocha based.
6//
7// You can provide your own test runner if you want to override it by exporting
8// a function run(testRoot: string, clb: (error:Error) => void) that the extension
9// host can call to run the tests. The test runner is expected to use console.log
10// to report the results back to the caller. When the tests are finished, return
11// a possible error to the callback or null if none.
