Angular tests fails with ng e2e but pass with protractor conf.js

while working on test automation for angular apps, i faced a problem that whenever I try to run the test suit with angular command ng e2e all the tests fail. The same tests get passed with protractor command protractor conf.js. I want to ask the reason for this weird behavior. The spec is provided. Thanks

import { AddMemberClass } from '../../pages/add-member/add-member.page';
import { LoginPage } from '../../pages/login/login.page';
import { browser, promise, by } from 'protractor';


fdescribe('Add Member as Admin',()=>{

    let addMemeber: AddMemberClass;
    let login : LoginPage;

    beforeAll(()=>{
        login = new LoginPage();
        addMemeber = new AddMemberClass();
        return new Promise((resolve)=>{
            login.navigateTo().then(()=>{
                login.getEmailInput().sendKeys('something@gmail.com');
                login.getPasswordInput().sendKeys('13235');
                login.getLoginButton().click().then(()=>{
                    setTimeout(()=>{
                        expect(browser.getCurrentUrl()).toContain('organization').then(()=>{
                            resolve();
                            });
                    },30000);
                });
            });
        });    
    });
