Can end-to-end tests in Visual Studio Team Services Build be run?
<p>I have a set of mocha tests that launch Spectron to do end-to-end testing on an Electron application.</p>

<p>When I try to run the tests through <code>npm run</code>, they just time out and fail. It seems that the application isn't launching. There is a <code>Run Functional Tests</code> build step template in VSTS, but that's for an actual test DLL. Is there something similar for Javascript end-to-end testing?</p>
