Best Unit Testing Tools in 2020

Unit Testing Tools

In this post, we will see the Best Unit Testing Tools for 2020.

This post summarizes the top unit testing tools that have the potential to help organizations to best position themselves to keep pace with the trends in software testing. The list includes both open-source and commercial unit testing tools. 

What is Unit Testing?

Unit Testing is also called Module Testing or Component Testing. It is done to check whether the individual unit or module of the source code is working properly. It is done by the developers in the developer’s environment. Read more on Unit Testing here.

Unit Testing Tools help developers in improving the quality of their code, reduce their time in terms of testing their own code, and also decrease overall cost. So we need to be careful while choosing an unit testing tool. Let’s see some of the popular tools for the unit testing process.

  1. JUnit
  2. NUnit
  3. TestNG
  4. JMockit
  5. EMMA
  6. PHPUnit
  7. xUnit.net
  8. Cantata
  9. TestComplete
  10. Mocha
  11. Jasmine

Features of Unit Testing Tools:

Now in this section we will see the above tools in detail.

JUnit:

JUnit 5 is the next generation of JUnit. The goal is to create an up-to-date foundation for developer-side testing on the JVM. This includes focusing on Java 8 and above, as well as enabling many different styles of testing.

NUnit:

NUnit is a unit-testing framework for all .Net languages. Initially ported from JUnit, the current production release, version 3, has been completely rewritten with many new features and support for a wide range of .NET platforms.

TestNG:

TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalities that make it more powerful and easier to use, such as:

  • Annotations.
  • 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 that your code is multithread safe.
  • Flexible test configuration.
  • Support for data-driven testing (with @DataProvider).
  • Support for parameters.
  • Powerful execution model (no more TestSuite).
  • Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc…).
  • Embeds BeanShell for further flexibility.
  • Default JDK functions for runtime and logging (no dependencies).
  • Dependent methods for application server testing.

JMockit:

JMockit is open source Unit testing tool. JMockit is a Java toolkit for developer testing, including mocking APIs and a code coverage tool.

  • Out-of-container integration testing for Java EE and Spring-based apps
  • Mocking API with recording & verification syntax
  • Faking API for replacing implementations
  • Code coverage tool

EMMA:

EMMA is an open-source toolkit for measuring and reporting Java code coverage. EMMA distinguishes itself from other tools by going after a unique feature combination: support for large-scale enterprise software development while keeping individual developer’s work fast and iterative. Every developer on your team can now get code coverage for free and they can get it fast!

  • EMMA can instrument classes for coverage either offline (before they are loaded) or on the fly (using an instrumenting application classloader).
  • Supported coverage types: class, method, line, basic block. EMMA can detect when a single source code line is covered only partially.
  • Coverage stats are aggregated at method, class, package, and “all classes” levels.
  • Output report types: plain text, HTML, XML. All report types support drill-down, to a user-controlled detail depth. The HTML report supports source code linking.
  • Output reports can highlight items with coverage levels below user-provided thresholds.
  • Coverage data obtained in different instrumentation or test runs can be merged together.

PHPUnit:

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

xUnit.net:

xUnit.net is a free, open source, community-focused unit testing tool for the .NET Framework. Written by the original inventor of NUnit v2, xUnit.net is the latest technology for unit testing C#, F#, VB.NET and other .NET languages. xUnit.net works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation, and operates under their code of conduct. It is licensed under Apache 2 (an OSI approved license).

Cantata:

Cantata is a unit and integration testing tool, enabling developers to verify standard compliant or business critical code on host native and embedded target platforms.

Cantata helps accelerate compliance with the standard’s dynamic testing requirements by automating:

  • Test framework generation
  • Test case generation
  • Test execution
  • Results diagnostics and report generation

TestComplete:

TestComplete is an automated testing environment for a wide range of application types and technologies, including (but not limited to) Windows, .NET, WPF, Visual C++, Visual Basic, Delphi, C++Builder, Java and Web applications and services.

 

Mocha:

Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub.

Jasmine:

Jasmine is a behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM. And it has a clean, obvious syntax so that you can easily write tests.
