JUnit vs Selenium: What are the differences?

# Introduction
In this markdown, we will discuss the key differences between JUnit and Selenium.

1. **Programming Language**: JUnit is specifically designed for Java programming language testing, whereas Selenium supports multiple languages such as Java, Python, C#, etc.
2. **Purpose**: JUnit is primarily used for unit testing individual classes or units of code, while Selenium is used for functional and regression testing of web applications.
3. **Testing Scope**: JUnit focuses on testing code at a unit level, while Selenium allows for end-to-end testing of web applications including user interface interactions.
4. **Integration**: JUnit is integrated with popular IDEs like Eclipse or IntelliJ for writing and executing tests, whereas Selenium requires additional tools like WebDriver to effectively automate browser interactions.
5. **Execution Environment**: JUnit tests are executed within the JVM (Java Virtual Machine), while Selenium tests run in browsers like Chrome, Firefox, etc.
6. **Dependencies**: JUnit tests can be run independently of any external dependencies, while Selenium tests require a set up of web drivers and browser configurations.

In Summary, JUnit is focused on unit testing in Java, while Selenium is used for web application testing across multiple languages and browsers.

Detailed Comparison

Selenium	JUnit
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.	JUnit is a simple framework to write repeatable tests. It is an instance of the xUnit architecture for unit testing frameworks.

What are some alternatives to Selenium, JUnit?

BrowserStack

BrowserStack is the leading test platform built for developers & QAs to expand test coverage, scale & optimize testing with cross-browser, real device cloud, accessibility, visual testing, test management, and test observability.

Sauce Labs

Cloud-based automated testing platform enables developers and QEs to perform functional, JavaScript unit, and manual tests with Selenium or Appium on web and mobile apps. Videos and screenshots for easy debugging. Secure and CI-ready.

LambdaTest

LambdaTest platform provides secure, scalable and insightful test orchestration for website, and mobile app testing. Customers at different points in their DevOps lifecycle can leverage Automation and/or Manual testing on LambdaTest.

Karma

Karma is not a testing framework, nor an assertion library. Karma just launches a HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like.

Robot Framework

It is a generic test automation framework for acceptance testing and acceptance test-driven development. It has easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach. Its testing capabilities can be extended by test libraries implemented either with Python or Java, and users can create new higher-level keywords from existing ones using the same syntax that is used for creating test cases.

Karate DSL

Combines API test-automation, mocks and performance-testing into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Besides powerful JSON & XML assertions, you can run tests in parallel for speed - which is critical for HTTP API testing.

Playwright

It is a Node library to automate the Chromium, WebKit and Firefox browsers with a single API. It enables cross-browser web automation that is ever-green, capable, reliable and fast.

Rainforest QA

Rainforest gives you the reliability of a QA team and the speed of automation, without the hassle of managing a team or the pain of writing automated tests.

WebdriverIO

WebdriverIO lets you control a browser or a mobile application with just a few lines of code. Your test code will look simple, concise and easy to read.

Cucumber

Cucumber is a tool that supports Behaviour-Driven Development (BDD) - a software development process that aims to enhance software quality and reduce maintenance costs.
