8 Useful Tools/Frameworks for Java Testing

Javatesting design.png

A plethora of tools is available in the tech market for automated testing of Java/J2EE applications. However, for this blog, I have winnowed down the long list of Java testing tools to the most used and popular ones, based on the reviews of some Java developers I recently talked to. So, don’t feel offended if I miss out on your favorite Java testing tool, as there is no perfect tool in this world. The 8 Java testing tools/frameworks I am going to discuss in this blog are meant for unit testing or functional testing or for specific types of Java components such as view, logic and validation components.

8 Useful Tools/Frameworks for Java Testing

#1 JUnit

Without a doubt, JUnit is the most popular Java testing framework out there. The framework is open source and is widely used by Java developers for writing & executing unit test cases. JUnit has also been one of the major forces behind the adoption of test-driven development methodologies. JUnit comes as a packaged JAR (Java ARchive) library, and you can download junit.jar and hamcrest-core.jar files from GitHub before placing them in your test class path.

The Java testing framework is very simple to use, and provides annotations for test method identifications. Assertion is another exciting feature of JUnit which it uses to test the expected results. With JUnit, Java developers can quickly run unit tests and get instant results via red/green progress bar.

Although JUnit is a popular unit testing framework, it can also be used for integration and acceptance tests. So, you can easily integrate JUnit with standard IDEs, like eclipse and netbeans.

#2 JWalk

JWalk is a Java testing tool that relies on Lazy, Systematic Unit Testing. The tool performs bounded exhaustive testing of any compiled Java class, supplied by the programmer.

Although JUnit enables to frequently retest the modified code, the manually created test scripts often remain incomplete. But that’s not the case with JWalk, which operates directly on the compiled code for Java classes and uses a new lazy method for inducing the changing design of a class on the fly. Besides, fully automated checking gradually takes over manual inspection of the test report.

For systematic testing, JWalk performs exhaustive testing of the whole state-space of the object to ensure compliance with the specification. The tool is smart enough to infer the specification from hints supplied by the programmer during the testing process, and from smart assumptions made about the intended design of the code…..

10 Useful JavaScript Form Validation Libraries

For Internet users, form filling on many websites and mobile applications has become a common exercise to provide information, like email ID, name, product delivery address, etc, in order to use the services. After putting the required information, the form validates the information and allows you to use the services. However, form validation often frustrated many Internet users in the past as any wrong or incomplete information resulted in the page reload, forcing them to enter the whole correct information again.

But, problems don’t last forever in the technology world. That said, I am unveiling 10 useful JavaScript form validation libraries that show instant alert whenever an Internet user enters any wrong information, thereby saving the time of entering the whole information again. These JavaScript form validation libraries check the veracity of the information entered before sending it to the server. As a result, an invalid info dialog instantly appears in front of the info tab in which wrong information was entered, which saves the time and hassles of putting the whole correct information again.

Why Developers Now Compare Vue.js to JavaScript Giants Angular and React?

Vue-js-Angular-React.png

Vue.js, an MIT-licensed open source project, is a JavaScript library for building web interfaces. The library was first released in 2013, but not many developers took cognizance of it in web framework technology for the next two years. It was 2016 when Vue.js rose to fame and gained so much traction that it’s now seen as an alternative for even well established JavaScript libraries, such as Angular and React.

Since Angular belongs to search engine giant Google and React comes from social media behemoth Facebook, developers still trust and use those libraries more than Vue.js. However, Vue.js showed enough strength last year to make waves on the internet and emerge as a potential candidate to surpass the reach of Angular and React in many cases. This blog attempts to shed light on why there is a growing belief among developers that Vue.js is set to become the top JavaScript library, leaving behind Angular and React.

Check Out Vue.js Achievements in 2016

  • 1,531,217 NPM downloads

  • 26,000 Github Stars

  • 100,696,367 pageviews on Vuejs.org page

  • Vue.js version 2.0 launched in September 2016

  • Vue.js was 3rd most starred project in 2016 on GitHub

Why is Vue.js considered to be Better than Angular and React?

Vue.js is a lightweight and easy-to-learn library, with facilities like two way data binding and virtual DOM. Unlike Angular and React that often inundate developers with myriad things to develop an app, Vue.js is simple and only calls for things that you need to effectively develop an app. Besides, Vue.js is relatively new, therefore obviates the need of acquainting yourself with its history before starting using it…Read full blog here- Why Developers Now Compare Vue.js to JavaScript Giants Angular and React?

 

Python 3.6 adds New secrets Module for Robust Account and Password Security

python-ev

Python 3.6, the newest major release of the Python language, has added a new module, called secrets, to help generate cryptographically strong random numbers for managing secrets, like account authentication, tokens and related secrets. Python developers are highly likely to prefer secrets over the default pseudo-random number generator in the random module, since it’s not meant for cryptography or security, but modelling and simulation.

Let’s understand with an example how one can create their own cryptographically strong pseudo-random values and generate tokens using the secrets module.

How to create Cryptographically Strong Pseudo-Random Values using secrets

>>> import secrets
>>> import string
>>> characters = string.ascii_letters + string.digits
>>> secure_password = ”.join(secrets.choice(chNo Records.aracters) for i in range(10))
>>> secure_password
‘SRvM54ZAs1’

The first step is to import the secrets and the string modules. Then we create a string of uppercase letters and integers. Now, in order to choose characters randomly to generate a secure password, we need to use the secrets module’s choice() method. The reason it’s being called a secure password is because there’s been a use of mixed case, numbers and symbols in the password, which is highly advised to people to keep their passwords protected from hack attacks…Read full blog here- Python 3.6 adds New secrets Module for Robust Account and Password Security

Why to Use HTML5 and CSS3 for Your Business?

CSS-HTML5.png

HTML, an abbreviation of Hyper Text Markup Language, first came into existence in late 80s to help describe a document’s structure and to allow cross-linking of documents. HTML has evolved multiple times since then, and many developers worldwide use it to provide better, faster, more consistent user experiences for desktop and mobile visitors. HTML now enjoys the close association with two allies – CSS and JavaScript. CSS enhances the appearance of HTML by describing the way the document is supposed to look. JavaScript, on the other hand, makes HTML more interactive. However, in this blog we will focus on the benefits of using the latest versions of HTML standard and CSS for business purpose.

As more and more people now prefer smartphones or tablets over PCs to surf the internet, mobile friendly sites with good user experience have become the need of the hour. Paying heed to the current demands of rich media, cross device and mobile internet access requirements, the World Wide Web Consortium (W3C) in October 2014 published HTML 5, the fifth and the latest version of the HTML standard.

A Brief Introduction to HTML5

One of the biggest differences between HTML5 and previous versions of the HTML standard is that it provides one common interface to load elements in multiple browsers. Since the older versions of HTML require proprietary plugins and APIs, a web page that was built and tested in one browser may not load correctly in another browser. But same is not the case with HTML5, which completely obviates the need of installing a Flash plugin by allowing the element to run by itself.

HTML5 was designed keeping in mind cross-platform mobile application development. Besides, new syntactic features in HTML5, like video, audio and canvas tags, were specifically introduced to support multimedia on mobile devices. Offline storage is also one of the virtues of HTML5…read full blog here- Why to Use HTML5 and CSS3 for Your Business?
