Protractor 2.5.1 ReferenceError: testFn is not defined

Question

I recently upgraded to protractor 2.5.1 and all of my tests are now failing. I suspect it is something to do with Jasmine but I'm not sure how to fix. Any help would be appreciated, thank you in advance. Here is the error I receive:

Should login successfully
Message:
ReferenceError: testFn is not defined

Here is my test, however the browser never even navigates to the baseUrl, it just shuts down.

import {Login} from "./Login";

describe("Login", () => {

beforeAll(() => {
    browser.get(browser.baseUrl);
});

it("Should login successfully", () => {
    Log.login(browser.params.login.username, browser.params.login.password);
    expect(browser.getLocationAbsUrl()).toBe("/");
});
});

This is because you are running in the "strict" mode and jasminewd2 had this problem when testFn was undefined. The fix was made in November and since Protractor depends on jasminewd2, upgrading to the latest Protractor would, surely, fix the issue.
