Selenium Tool Suite - Components and Features

Selenium is an automation testing tool; it is primarily used to test websites and web applications; it is an open-source tool. With the help of Selenium, test cases can run directly in web browsers, just like a person operating the web browsers. It supports many web browsers such as Opera, Safari, Chrome, Firefox, IE, etc. There are several different sub tools to support different automation test approaches. In this article, we will learn about selenium tool suite, its components and features. So let’s start!!!

WebDriverIO Tutorial: Handling Alerts and Overlay In Selenium

You’d hardly find a website these days without alerts and pop-ups! The alert boxes warn you whenever you perform a wrong action or to enter details to access a website. These alert boxes stop you from performing any other browser functions till the alert is resolved. This is why it becomes important that you handle them in your Selenium test automation scripts.

In this WebDriverIO tutorial on alert handling in Selenium, I’ll show you how to handle alerts and pop-ups as well as overlay modal in WebDriverIO. I will also cover the different types of alerts you will face during automation and what are the key points you need to follow for alert handling in Selenium using WebDriverIO.

Types Of Alerts In WebDriverIO

Alerts and pop-ups are pretty common in any website development, and while performing Selenium test automation you have to handle them as well. These alerts or rather javascript alerts, are pop up that takes your attention away from the current browser and forces you to read them. You won’t be able to perform any further browser action if you don’t know how to handle the alerts, this stands true for both manual and automation.

It is important to note that you can’t identify alerts using devtools or by XPath. Also, since they can’t be handled as a window, this is why it gets a bit tricky to handle them, but don’t worry, you’d find more about this in the latter section of this WebDriverIo tutorial.

There are three types of alerts that you’d need to handle in WebDriverIO.

  1. Alert pop up
  2. Confirmation Alert
  3. Prompt pop up

Alert Pop Ups

The alert pop up or alert() method displays an alert box with just a message and ‘OK’ button. This alert used to inform the user about some information. There is only one button ‘OK’ displayed with the text of information. Here, the user has only one option to press the OK button. Below is the example of alert pop up.

JavaScript Alerts

Confirmation Alert

The confirmation alert is the second type of alert with a message, where it gives the user the option to press OK or Cancel. Here is the example of a confirmation alert.

Confirmation Alert

Prompt Pop-Up

The prompt pop up is the last alert where this used to let the user give input for the website. Here, the user can give input and press the OK button or press Cancel to avoid giving input. Below is the example of the prompt pop up.

Apart from these in-built javascript alerts, there is also one more pop up which is known as modal. The main difference between an alert and modal is that alert can not go off without requested actions e.g, OK, or Cancel. In the modal, it is made using the < div > tag by giving special CSS code. This modal can go off by clicking somewhere other than the modal.

Overlay Modal

This modal is built using the client-side framework e.g bootstrap, ReactJS. A developer can be used to display some information, pop up, and form. There is no special

Here is an example of Overlay Modal:

Now, that you are familiar with a different kind of alert and modal available in javascript. I’ll show you more about alert handling in Selenium in this WebDriverIO tutorial.

Docker Explained: Docker Architecture | Docker Registries

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub

In this video lesson you will learn:

  • What is Docker Host
  • What is Docker Engine
  • Learn about Docker Architecture
  • Learn about Docker client and Docker Daemon
  • Docker Hub and Registries
  • Simple demo to understand using images from registries

Selenium Grid With Docker Swarm

In this guide, we will talk about setting up a Selenium Grid using Docker Swarm on any of the cloud services like GCP or AWS.

Let’s start with the basics first, i.e. what is Selenium Grid and Docker Swarm.

What is Selenium Grid?

Selenium Grid allows the execution of WebDriver scripts on remote machines (virtual or real) by routing commands sent by the client to remote browser instances. It aims to provide an easy way to run tests in parallel on multiple machines.

Selenium Grid allows us to run tests in parallel on multiple machines, and to manage different browser versions and browser configurations centrally (instead of in each individual test).

Selenium Grid purposes and main functionalities

  1. A central entry point for all tests
  2. Management and control of the nodes/environment where the browsers run
  3. Scaling
  4. Running tests in parallel
  5. Load balancing

Now a question comes “When to use Grid”?

Generally speaking, there are two reasons why you might want to use Grid.

  1. To run your tests against multiple browsers, multiple versions of browsers, and browsers running on different operating systems.
  2. To reduce the time it takes for the test suite to complete a test pass.

Grid is used to speed up the execution of a test pass by using multiple machines to run tests in parallel. For example, if you have a suite of 100 tests, but you set up Grid to support 4 different machines (VMs or separate physical machines) to run those tests, your test suite will complete in (roughly) one-fourth the time as it would if you ran your tests sequentially on a single machine.

What is Docker Swarm?

Docker swarm is a container orchestration tool, meaning that it allows the user to manage multiple containers deployed across multiple host machines.

One of the key benefits associated with the operation of a docker swarm is the high level of availability offered for applications. In a docker swarm, there are typically several worker nodes and at least one manager node that is responsible for handling the worker nodes’ resources efficiently and ensuring that the cluster operates efficiently.

What are the two types of Docker Swarm mode services?

Docker Swarm has two types of services: replicated and global.

**Replicated services: **Swarm mode replicated services functions by you specifying the number of replica tasks for the swarm manager to assign to available nodes.

**Global services: **Global services function by using the swam manager to schedule one task to each available node that meets the services constraints and resource requirements.
