SIMPLIFY YOUR AUTOMATED TEST CASES

Maintaining test automation can take a lot of time.  I have seen automation engineers creating test cases that are very long and that don’t have a clear purpose. If their test cases were more streamlined and focused, the teams that use them would save a lot of time.

Lets discuss how we can simplify those

1. Decrease your scope

2. Single Responsibility

3. Identify the simplest thing you can automate

4. Avoid unnecessary dependencies

and to summarise, Keep it simple, stupid

Angular - HttpClient

The browsers support two different APIs for making HTTP requests:
1. XMLHttpRequest interface
2. fetch() API

Angular 4.3 introduced a new HttpClient service, which is a replacement for the Http service from Angular 2.

The HttpClient in @angular/common/http offers a simplified client HTTP API for Angular applications that rests on the XMLHttpRequest interface exposed by browsers. Additional benefits of HttpClient include testability features, typed request and response objects, request and response interception, Observable apis, and streamlined error handling.

Setup

Before you can use the HttpClient, you need to import the Angular HttpClientModule.

import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { HttpClientModule } from '@angular/common/http'; @NgModule({ imports: [ BrowserModule, HttpClientModule, ], declarations: [ AppComponent, ], bootstrap: [ AppComponent ] }) export class AppModule {}

Having imported HttpClientModule into the AppModule, you can inject the HttpClient into an application class as shown in the following ServiceClient example.


import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; @Injectable() export class ServiceClient { constructor(private http: HttpClient) { } }


The ServiceClient fetches this file with a get() method on HttpClient.


srvUrl = 'srv/srv.json'; getConfig() { return this.http.get(this.srvUrl); }
