The spec stops running and hangs

问题

I've got a problem when using UIVeri5 to testing an app built by Fiori Elements. The test script is hanging there (for most of the time) at the first step until timeout. What's worse, I found in very rare case, it will succeed by passing the step. But the passing case cannot be easily reproduced.

Here is my partial_release.spec.js.

describe("partial_release", function () {
    it('should load the app', function() {
        debugger;
        expect(browser.getTitle()).toBe('Manage Security Deposits');
    });
});

The log stops like this:

It will stops until timeout for most of times, although the app stops at the very first screen (the list page) with the title "Manage Security Deposits" shown on the tab.

Lucily, after hundreds of times experiments, I successfully catch one passed case. See logs in console below.

Does anyone have a similar issue?
