IntelliJ IDEA vs Jest: What are the differences?
Introduction
IntelliJ IDEA and Jest are two widely used tools in the software development industry. While IntelliJ IDEA is an integrated development environment (IDE) primarily used for Java development, Jest is a JavaScript testing framework specifically designed for testing JavaScript code. Despite both being tools used in software development, there are several key differences between IntelliJ IDEA and Jest.
Language Support: One of the main differences between IntelliJ IDEA and Jest is the programming language they are designed to support. IntelliJ IDEA is primarily used for Java development, but it also supports a wide range of other programming languages like Kotlin, Groovy, Scala, and more. On the other hand, Jest is specifically designed for testing JavaScript code, making it suitable for projects developed using JavaScript or related frameworks like React.
Functionality: Another significant difference between IntelliJ IDEA and Jest is their functionality. IntelliJ IDEA is a comprehensive IDE that provides features like code completion, code analysis, debugging, version control integration, and more. It offers a wide range of tools and capabilities to assist developers in the software development process. Jest, on the other hand, is a JavaScript testing framework focused solely on providing an efficient and effective way to write and run tests for JavaScript code. It offers features like test suites, test runners, assertions, and mocking to facilitate the testing process.
User Interface: The user interface of IntelliJ IDEA and Jest also differs significantly. IntelliJ IDEA provides a rich and sophisticated UI with numerous options and settings. It allows developers to customize the layout, themes, and appearance according to their preferences. Additionally, it offers a variety of panels, windows, and toolbars to enhance productivity. Jest, on the other hand, has a much simpler UI with a command-line interface (CLI) or a minimalistic graphical user interface (GUI) for running tests and displaying test results.
Integration: Integration capabilities are another area where IntelliJ IDEA and Jest differ. IntelliJ IDEA seamlessly integrates with build tools like Maven and Gradle, allowing developers to easily manage dependencies, build, and run projects. It also integrates with popular version control systems like Git, enabling developers to perform version control operations directly from within the IDE. Jest, on the other hand, integrates well with JavaScript projects and frameworks like React, providing specialized features and tooling for testing JavaScript code.
Community Support: The level of community support for IntelliJ IDEA and Jest is another key difference. IntelliJ IDEA has a large and active community of developers who contribute to its ongoing development, share knowledge, and provide support through forums, blogs, and documentation. This vibrant community ensures that developers can find solutions to their problems and stay updated with the latest advancements in the IDE. Jest, although not as extensive as IntelliJ IDEA, also has a supportive community that provides assistance, shares best practices, and contributes to the improvement of the testing framework.
Purpose: Lastly, the purpose of IntelliJ IDEA and Jest differs. IntelliJ IDEA is primarily used for software development and provides a plethora of features and tools to aid developers throughout the development process. It enables developers to write, debug, test, and deploy Java (and other supported languages) applications efficiently. Jest, on the other hand, is solely focused on testing JavaScript code. Its purpose is to provide an intuitive and powerful framework for developers to write and run tests for JavaScript projects, ensuring the reliability and correctness of the code.
In summary, IntelliJ IDEA is an extensive IDE used for various programming languages, including Java, while Jest is a specialized JavaScript testing framework focused on testing JavaScript code. IntelliJ IDEA offers a comprehensive set of features for software development, whereas Jest concentrates solely on providing efficient testing capabilities for JavaScript projects. Their language support, functionality, user interface, integration capabilities, community support, and purpose are the major differences between these two tools.
UPDATE: Thanks for the great response. I am going to start with VSCode based on the open source and free version that will allow me to grow into other languages, but not cost me a license ..yet.
I have been working with software development for 12 years, but I am just beginning my journey to learn to code. I am starting with Python following the suggestion of some of my coworkers. They are split between Eclipse and IntelliJ IDEA for IDEs that they use and PyCharm is new to me. Which IDE would you suggest for a beginner that will allow expansion to Java, JavaScript, and eventually AngularJS and possibly mobile applications?
Pycharm is great for python development, but can feel sometimes slow and community version has Somme very annoying restrictions (like they disabled jupyter notebooks plugin and made it premium feature). I personally started looking into VS Code as an alternative, and it has some very good potential. I suggest you take it into account.
The Community version of PyCharm is free and should give you what you need to get started with Python. Both PyCharm and IntelliJ are made by JetBrains. IntelliJ is initially focused on Java but you can get plugins for lots of other things. I subscribe to JetBrains' Toolbox: https://www.jetbrains.com/toolbox-app/ and have access to all of their great tools.
Hi, I will give my opinion based on my experience. I have used PyCharm, both community and Professional version. The community has limited functions, like you can't use a Jupyter notebook whereas it's available in the Professional version. PyCharm is slower compared to Visual Studio Code. Also Visual Studio Code is an editor which supports various languages. I myself have used both Visual Studio Code and PyCharm. I feel Visual Studio Code would be better choice. You may as well decide based upon your requirements.
I couldn't imagine using a development tool other than the IntelliJ IDEA Ultimate All Products Pack. A single license allows me to work directly on my server running Ubuntu and/or my workstation running Windows 10 Pro simultaneously. My current project uses HTML, W3CSS, JavaScript, Java, Groovy, Grails, C, GO, Python, Flask, and Rust. For me it's worth every penny of the $150 license fee. And you can try it for free.
I'd personally recommend Visual Studio Code as it gives you the flexibility of working in any language, so long as there are extensions to support it. It gives you the flexibility to learn Python, venture into Java, Javascript, and eventually AngularJS, and potentially mobile applications. It's also free and you can install it on your personal computer. I think Visual Studio Code would serve your intended use case best.
Visual Studio code is easy to use, has a good UI, and a large community. Python works great with it, but unlike some other editors, it works with most languages either by default or by downloading a plugin. VS Code has built in linting, syntax coloring, autocompletes (IntelliSense), and an api for plugins to do there own tooling.
If you starting with Python then PyCharm is better. For Java I would suggest to go with IntelliJ IDEA but people also prefer eclipse so I would say try both and then decide. For JS/Angular/React I would suggest go with VSCode. I personally use it and prefer as its light weight and have good integration with chrome for frontend development.
PyCharm, IntelliJ IDEA are both products of JetBrains. They have a free (limited feature) and paid edition. Eclipse is free. VSCode is also free.
IntelliJ really is the best for Java, I switched from eclipse years ago and never looked back. As for javascript, python and angular either using the standalone products from jetbrains (pycharm for python, webstorm for js) or installing the relevant plugins for InteliJ will be your best bet. Pycharm etc. are really just InteliJ with some additional plugins installed.
All three are great, however, I believe that IntelliJ IDEA's multiple IDE's are slightly more straight-forward and more up-to date than Eclipse. If I had to choose one specifically for Python projects I would go with PyCharm.
Pycharm is all you need to get start coding in python or any of its framework. Its an awesome tool you should give it a try :)
Easy to learn and everything you need
This is a very easy to use tool and gives you the opportunity to start coding right after the installation with almost everything setup automatically by the tool.
I originally chose IntelliJ over Eclipse, as it was close enough to the look and feel of Visual Studio and we do go back and forth between the two. We really begin to love IntelliJ and their suite of IDEs so we are now using AppCode for the IOS development because the workflow is identical with the IntelliJ. IntelliJ is super complex and intimidating at first but it does afford a lot of nice utilities to get us produce clean code.
As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.
Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.
