Introduction to Automation Testing with Cypress for the Modern WebAbout Cypress

Cypress is a front end automation tool created for the modern web. Cypress is built using new architecture and it runs in the same run-loop as the application under test. This results in Cypress providing better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.

Cypress’s Features

Some of the key features of Cypress are Time Travel, Debug ability, Automatic wait, Spies, Stubs, and Clocks, Network Traffic Control, Consistent Results, Screenshots and Videos

What you may like:

Cypress does not use Selenium as most of the other end to end testing tools are using Selenium, that’s why others have almost the same problems

Easy and effortless installation and updating. If you’re using Node.js and want to install Cypress in the project it will be just a single line in the console. (npm install cypress)

Cypress supports any framework or website quite well. There are thousands of projects built using the latest React, Angular, Vue, Elm, etc. frameworks. Cypress also works equally well on server-rendered pages or applications.

Cypress tests are only written in JavaScript. While one can compile down to JavaScript from any other language, ultimately the test code is executed inside the browser itself. There are no languages or driver bindings – there is and will always be just JavaScript.

Cypress has no issues with nodes, their versions, and related dependencies.

It has an awesome dashboard and a preview window. Just look at the screenshot below. It gives you a precise overview of what’s being tested.

Screenshot for every step, of the script, which can be quite helpful if there, is any false passing or failing test which is good for debugging also.

The broad range of debugging and testing tracking options. The list has integration with dev tools, screenshots, snaps, etc

Headless option and ease of integrating with CI. At present, Cypress can be integrated with around 15 CI providers. Cypress runs much faster with end to end tools.

Network traffic control. i.e. Detection, debugging, verification, waiting for requests

Eliminating all sorts of timers. Cypress features a built-in mechanism to handle waiting for DOM elements

Easy to use & intuitive syntax (Mocha and Chai are all there)

Wide range of selectors plus Cypress ‘built-in’ commands serves all requirement

What you may dislike:

The structure is different from the other Selenium end to end tools, so in the first place need to spend more time understanding.

Community: As Cypress is relatively new may find trouble getting answers

No native event handling capabilities like files upload etc. & No cross-browsers testing.

No Page Object Model, It supports an altogether different approach

It’s only available for only one client (language) i.e. for JavaScript only.

                       Pros and Cons: Cypress vs. Selenium

The most important question for any business willing to develop an application is that “which front-end technology (client-side) should they choose?” With numerous options for JavaScript frameworks available within the app development sphere, your app development team must take care of their choice.

In this top-notch technology world, your security testing company or in-house the team needs a far better thanks to developing and deploy an interactive web app for your business which will earn you the specified ROI. Being an entrepreneur or business owner, you would like to stay your tech guide handy for better deciding. Well, I even have seen my clients getting confused about the front-end technology and curious to understand more about it.

This article holds a transparent detail about ReactJS vs AngularJS vs VueJS and which technology to pick for your web app in 2020.

What is AngularJS?

AngularJS is an open-source front-end web app framework by Google that holds a Model-View-Controller (MVC) architecture makes the event, maintenance, and testing easier for developers. Through AngularJs development companies you can create highly active and interactive web applications but a hottest for single-page applications.

Benefits of AngularJS:

1) Web and application built on AngularJS runs in any browser environment no matter the platform.

2) The two-way or bidirectional data binding ensures the info change within the model will reflect within the view immediately, and when data within the view changes, the model is additionally updated.

3) The pre-built material design components help in building a highly interactive and simply navigable UI for your mobile/web app.

What is React JS?

Introduced by Facebook, ReactJS is an Open-Source JavaScript library for building an interactive, stateful & reusable interface (UI). React web development process good for rendering complex UI with high performances and also works with the essential fundamental of the virtual Document Object Model (DOM) to supply a highly stable web application.

Benefits of ReactJS:

1) Virtual DOM helps React app developers a simple rendering of any changes within the application without affecting the opposite parts of the interface.

2) Js allows the reusing of its code components anytime for various levels. This makes app development easy and time-saving.

3) ReactJS uses Redux which simplifies the storing and managing component states in large applications.

What is VueJS?

Vue.js may be a progressive JavaScript Framework for building web user interfaces. Vue is meant from the bottom up to be incrementally adoptable. It comes with various optional tools for building user interfaces. Vue features a high capability of backing sophisticated Single-Page Applications when utilized in combination with modern tooling and supporting libraries.

Benefits of VueJS

1) One of the foremost significant benefits of Vue.js is its small size. It takes less time for the user to download and use it.

2) It facilitates web developers to integrate with the prevailing applications built-on JavaScript.

3) It comes with detailed documentation that helps developers to create both small also as large scales templates saving tons of your time.

Popularly known as ‘bespoke software’, it is an application designed to cater to the specific needs of a particular business organization. Personalized or customized software is mostly designed for a single client but at times it also serves the business needs of a group of organizations. It is completely on the business owners to decide what features the custom software development services need to endow in the customized software for more effective operations.

Why is customized software so sought after?

Of course, there is software readily available that would provide you nothing special or customized, but you can also instruct software developers to build software from scratch so that it suits your business requirements. The benefit of readily-made software is that in this case, you don’t have to invest in the time to interact with the software developers’ team to design your software.However, you should keep in mind that these applications available in outlets are purely generic and might offer some functionalities which might not be of any use to you.Even after spending a fortune for ready-made software, if your specific business needs are not being fulfilled, then look at the benefits of custom software.

Business process optimization

Each and every organization possesses its own business model and a set of processes alongside it. Now if you invest in a generic software package, however effective it may be, it would be very difficult for you to tweak your business processes so that it is in sync with the application. That is why; software should be developed in a model so that it aligns with the business model and also goes in sync with the unique processes of an organization. So if you decide to consider custom software you do not have to replace your business operations, instead you can optimize the existing business operations.

As you would have the first and the last say in deciding what features your software should be endowed with. If you are inclined towards trendsetting technologies, then you can get your software designed with the help of innovative technologies so that it can turn out the way you want. This is perhaps the greatest advantage of customized software because it allows the maximum level of customization to suit every specific need of your company. Moreover, it also allows you the scope for scalability.

Using standardized software for your business can be easy and fast, but when it comes to scalability, ready-made applications often prove to be inadequate. When it comes to business and its evolving and ever-changing requirements, you never know when you need to fit in newer features in the software. So instead of going for a complete overhaul of the existing software landscape, it is much easier to modify certain modules and scale up your company software for meeting new requirements. Now, this is only possible when you have customized software, instead of a standard one.

Make your business stand out

If you have been in the business for at least a few years, then you would already know that every business is unique, and so are their needs. As far as business processes are concerned, there is no one-size-fits-all business application. If your business model is one of a kind, then having tailor-made software to suit your business process will hugely act in your favor. If you want to create and support your unique identity in the industry, then custom software development is the key to achieve it.

Enhancing the reliability of your business operations

You can only be successful if you manage to stick to your business model accompanied by a set of processes throughout. If you can rely on your business process then no one can even challenge you to earn success.But, to check reliability you should conduct proper testing of your custom software as it implies that you have a powerful IT tool in your possession which would trigger the growth of your business in the long-term.

Emphasize commitment towards your business

If you show keenness to develop custom software to fulfill your business needs, it shows to the industry that you value in-house operations and you value your customers as well. As with the assistance of a custom software development, you are streamlining your business operations and model you are showing commitment towards your organization to focus on its betterment while growing with your clients. So in other words, it gives off a very genuine and positive impression that helps in building goodwill and brand reputation.

Adapting to new market trends

Organization processes are bound to change with time, keeping in sync with the industry trends. To strengthen and maintain your marketing stronghold, you will have to adapt to new business processes and ground-breaking technologies. The best thing about customized software is that it can be changed with great ease, and when new marketing trends will emerge, new technologies can be integrated with the existing one with the help of software developers.

Maintain your reliability and uniqueness

Reliability is one of the most crucial parameters for a business to succeed. When you have a reliable customized software it automatically conveys and maintains this authenticity, and emphasizes your originality too. Now, uniqueness is something that indeed distinguishes your brand from the countless others in the same industry; after all, that is what makes you stand out amidst competition carving a distinct niche for your brand. When you are recognized for your uniqueness and authenticity, you will never have to look back as far as business success is concerned.

Apart from these benefits, you would also be able to reduce the cost of your daily business operations. You can even cut down on your investment of huge funds for customized software development because there are flexible packages as well. 

Choosing a customized software is surely a smarter choice without any doubt. But make sure that you choose the right custom software development services provider company for the purpose.

Apache JMeter is an open source testing software. JMeter is a 100% pure Java desktop application which is used for performance testing and analyze the overall system performance under different loads.

JMeter is user friendly and can be downloaded for free of cost. JMeter was originally used for testing Web Application or FTP application. Today, it is used for a functional test, database server test etc.

Many protocols that are supported by JMeter:

HTTP,     HTTPS sites

Web     Services

Database     via JDBC drivers

Directory     – LDAP

JMS     (Java Message Service)

SMTP(     Simple Mail Transfer Protocol)

FTP     Services( File Transfer Protocol)

JMeter Advantage:

            Open source license

            Friendly user interface

            Record and playback feature

            Easy installation

            Multi-threading framework

            Multiple protocol supported

 Basic Components of JMeter:

Test Plan: It is a root feature in JMeter tool where all the settings are described/mentioned for executing a test. It describes all the  steps and JMeter has to execute when tests are run. A test plan consists of Thread Group, Timers, Config Elements, Listener, Assertion, pre/post processers etc. JMeter offers various customization as it can be used depending upon the user requirement.

Thread Group: Thread Groups can be defined as a collection of Threads. Each thread represents one user using the application under test.

Basically,each and every thread simulates one real user request to the server. The thread group elements are responsible for handling the number of threads. We can manage following things by using thread groups:

Number     of threads to run

Ramp     up time (period of time in seconds, that tells JMeter how long it takes to     start all the threads)

Number     of iteration (Loop count)

Sampler: Now, we already know that Thread Groups simulate user request to the server

But how does a Thread Group will understand which type of requests (HTTP, FTP etc.) it needs to make?

The answer is Samplers

Sampler is responsible for sending a specific type of request to the server. For instance, we can have an HTTP Request Sampler if we need to perform different operations like POST, GET, DELETE on HTTP services or web applications.

JMeter has a different type of sampler.  HTTP Request Sampler is the sampler used for testing web applications. Samplers do the actual work for JMeter and are responsible for generating one or more sample results. Some majorly used samplers are listed below:

HTTP     Request

FTP     Request

JDBC     Request

Java     Request

SOAP/XML     Request

SMTP     Sampler

BSF     Sampler

Debug     Sampler

Listeners: Listener records the results generated by the samplers. Listeners show the results of the test execution. The result can be shown in a different format such as a tree, table, graph or log file.

Listeners also provide the different response time matrices (average time, minimum time, max time, etc) of a Sampler request. Also, If there are a lot of samplers in a thread group, then listener may consume a lot of memory.

Some listeners provided by JMeter are:

View     Results in Table

Graph     Results

Assertion     Results

View     Results Tree

Aggregate     Report

Mailer     Visualizer

Simple     Data Writer

Aggregate     Graph

Bean     Shell Listener

Summary     Report

Assertion: Assertion in JMeter is responsible for validating the response of the request that users have sent to the server. It is a process where you verify expected result with the actual result of the request at run time. If you need to apply assertion on a particular Sampler, then users have to add it as a child of that Sampler.

Assertion results can be viewed by adding “Assertion Listener” to the Thread Group. If an assertion gets fail, the sampler request is marked as failed and the same gets reflected in the test results listeners.

Some Assertion listeners provided by JMeter are:

Bean Shell Assertion

BSF Assertion

Compare Assertion

Duration Assertion

HTML Assertion

Response Assertion

Size Assertion

SMIME Assertion

XML Assertion

XML Schema Assertion

XPath Assertion

How to add Assertion:

Simply, Right Click on a Sampler Request -> Hover over Add -> Hover Over desired Assertion -> Click on the required Assertion

Running Test Plan

Once the sampler(s) are ready, we can add a couple of reporting elements(Listeners) to gather statistics at runtime, and start the load test.

In the screenshot below, while our test is running, we can monitor the following things

Test Plan

Thread Group

Samplers – Registration

Assertion – Response Assertion

Listeners – View Result Tree, Summary Report
