Cypress Installation & Setup

In this Cypress testing tutorial, we will be doing the setup and installation on our local machine to get Cypress up and running.

One of the great things about Cypress is that using just one command you can get all the necessary packages installed to start writing your first test using Cypress. Let’s take a look at that –

Installation

To install Cypress locally, you need to run through the following steps –

  • Create a new npm project:
  • mkdir your_project_name && cd your_project_name
  • npm init -y to initialize your project
  • Install Cypress:
  • npm install cypress --save-dev

This will download and unzip the Cypress desktop client and install all the necessary packages for you.

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

  1. Installing Node.js and npm
  2. Installing Angular CLI
  3. Creating workspace
  4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Angular environment setup

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

  • npm Package Manager
Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

  1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

  • Using CLI
  • Using Visual Studio Code
1. Using CLI

To create a workspace:

  • Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
  • Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:
  1. Ng new YourAppName

create angular workspace

  • After running this command, it will prompt you to select from various options about the CSS and other functionalities.

installr: Functions for Installing Softwares From within R

installr

Introduction

The installr package offers a set of R functions for the installation and updating of software (currently, only on Windows OS), with a special focus on R itself. This package has two main goals:

  1. To make updating R (on windows) as easy as running a function.
  2. To make it as easy as possible to install all of the needed software for R development (such as git, RTools, etc), as well as for reproducible research using R (such as MikTeX, pandoc, etc).

Motivation

While for Linux users, the installation process of new software may be just running a short line of code, for the regular Windows user it often includes browsing online, finding the latest version, downloading it, running the installer, and deleting the installation file. All of these steps are automatically done using functions in this package.

Installation

To install the stable version on CRAN:

install.packages('installr')

To install the latest installr version from GitHub use:

if (!require('remotes')) install.packages('remotes'); # make sure you have Rtools installed first! if not, then run:
#install.packages('installr')
#install.Rtools()
remotes::install_github('talgalili/installr')

Usage

If you are using the Rgui, you will see a new menu added on your top right (just by "help"), giving you the option to update R, or install new software.

For command line use you can update R by running:

if(!require("installr")) install.packages('installr')
library("installr")
updateR() # this will open dialog boxes to take you through the steps.
# OR use:
# updateR(TRUE) # this will use common defaults and will be the safest/fastest option

Or install a new software simply by running:

library("installr")
installr() #  user can easily select (via a GUI interface) a software to install.

Troubleshooting

If you get either of the following errors from some commands:

Error in download.file(URL, destfile = ...) : 
  unsupported URL scheme

Or:

install.RStudio()
Error in file(con, "r") : cannot open the connection
updateR()
Error in file(con, "r") : cannot open the connection

Try running:

setInternet2(TRUE)
