ScalaTest vs TestNG: What are the differences?

Introduction: ScalaTest and TestNG are popular testing frameworks used in the Java ecosystem. They each have their own unique features and capabilities that cater to different testing needs.

Programming Paradigm: ScalaTest is primarily designed for Scala developers and is heavily focused on leveraging Scala's functional programming capabilities. On the other hand, TestNG is a Java-based testing framework that adheres more closely to traditional object-oriented programming principles.
Integration with Java: TestNG can seamlessly integrate with existing Java projects and frameworks such as Maven and Jenkins. ScalaTest, being more Scala-centric, may require additional setup and configuration to work within Java-based projects.
Testing Styles: ScalaTest supports a variety of testing styles including FunSpec, FlatSpec, WordSpec, etc., providing developers with flexibility in choosing the most suitable style for their tests. In contrast, TestNG follows a more conventional testing approach with annotations such as @Test, @BeforeMethod, @AfterMethod, etc.
Asynchronous Testing: ScalaTest has built-in support for testing asynchronous code through Futures, making it easier to write and execute asynchronous test cases. TestNG, while capable of handling asynchronous testing, may require additional setup and handling to achieve similar functionality.
Community and Ecosystem: TestNG has been around longer and has a larger community of users and contributors, leading to more extensive documentation, support, and plugins. ScalaTest, being more niche and Scala-specific, may have a smaller but dedicated community focused on Scala testing best practices.
Assertions and Matchers: ScalaTest comes with a rich set of built-in matchers and assertion libraries that enable developers to write expressive and readable test assertions. TestNG, while providing basic assertion capabilities, may require additional libraries or dependencies for more advanced assertion functionalities.

In Summary, ScalaTest and TestNG differ in terms of programming paradigm, Java integration, testing styles, asynchronous testing support, community size, and assertion capabilities.

Detailed Comparison

ScalaTest	TestNG
You can test Scala, Scala.js (JavaScript), and Java code with this tool. It makes it easy to take your testing to a higher, more productive level in new or existing Scala, Scala.js, or Java projects.	It is a testing framework designed to simplify a broad range of testing needs, it covers all categories of tests: unit, functional, end-to-end, integration, etc.Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc.
Test Scala, Scala.js (JavaScript), and Java code; Designed to grow with the demands of its users;Uses its own extension points to support several styles of testing out of the box	Support for data-driven testing ; Support for parameters; Powerful execution model (no more TestSuite); Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc

What are some alternatives to ScalaTest, TestNG?

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.

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.

TestCafe

It is a pure node.js end-to-end solution for testing web apps. It takes care of all the stages: starting browsers, running tests, gathering test results and generating reports.

Spock Framework

It is a testing and specification framework for Java and Groovy applications. What makes it stand out from the crowd is its beautiful and highly expressive specification language. It is compatible with most IDEs, build tools, and continuous integration servers.

Selenide

It is a library for writing concise, readable, boilerplate-free tests in Java using Selenium WebDriver.

Capybara

Capybara helps you test web applications by simulating how a real user would interact with your app. It is agnostic about the driver running your tests and comes with Rack::Test and Selenium support built in. WebKit is supported through an external gem.

PHPUnit

PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks.

Detox

High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. It tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user.

Imagium

Imagium provides AI based visual testing solution for various forms of testing. It makes the job easier for QA Automation, Mobile Testers, DevOps and Compliance teams. Imagium is easy to integrate with any programing language
