The protractor tool is unable to recognize an Angular component when it is displayed on the page

I have implemented end-to-end (e2e) testing on my project, but I am facing issues that are causing my tests to fail. Below is a snippet of my app.po.ts file:

import { browser, by, element } from 'protractor';

export class AppPage {
    public baseUrl: string = browser.baseUrl;

    public navigateTo(url?: string) {
        browser.get(url || '/');
    }

    public getPageTitle() {
        return browser.getTitle();
    }

    public getCurrentUrl() {
        return browser.getCurrentUrl();
    }

    public getText(selector: string) {
        let elementText = element(by.css(selector)).getText();
        return elementText;
    }
}

// More code here...

Here is an excerpt from my test file:

import { AddNotificationGroup, AppPage, LoginPage } from './app.po';

describe('Admin Panel: Sample flow', () => {

    // Test cases go here...

});

This text showcases some router configuration snippets as well :

[
    // Router configurations listed here...
]

Updated:

My AuthGuard implementation is shown below :

import { Injectable } from "@angular/core";
import { ActivatedRouteSnapshot, CanActivate, Router, RouterStateSnapshot } from "@angular/router";
import { Observable } from "rxjs/Rx";

@Injectable()
export class AuthGuard implements CanActivate {

    // Code for authentication guard

}

Explanation of the authentication process and how it affects the test results is provided. The issue of page generation failure during the tests is also addressed.

Answer №1

One tip that proved effective for me was to include the browser.get(['/login']) function before logging in with Protractor. This helped Protractor recognize the redirection triggered by the AuthGuard after entering input fields, sendingKeys, and clicking the login button. Interestingly, Protractor was able to handle the subsequent redirection post-login without requiring an extra browser.get command.
