With Automation

Best Practices for Java Developers

Application software developers often struggle with unit testing within their workflow. It requires a lot of skill and effort to create effective tests to validate unit functionality, and it takes commitment and time to maintain the test suites. This ebook offers best practices and tips to address common unit testing challenges.


Conquer Common Unit Testing Challenges

Unit testing is a well-known practice, but there's lots of room for improvement. Download our ebook for tips and techniques to improve unit testing within your development workflow.

Parasoft has focused on improving automated testing for over 30 years. Parasoft Jtest is a key enabler of delivering quality at speed for unit testing. This integrated Java solution enables development teams to be agile and deliver faster without sacrificing quality, making the business successful.

Unit testing is the practice of testing individual units or components of an application in order to validate that each of those units is working properly. Generally, a unit should be a small part of the application. In Java, it's often a single class. Note that there is no strict definition of "unit" here, and it is up to the developer to decide the scope of tested code for each test.

Unit testing is a proven technique for ensuring software quality. It has plenty of benefits. Here are some great reasons to unit test:
  • Unit testing validates that each piece of your software works properly today and continues to work in the future — providing a solid foundation for future development.
  • Unit testing identifies defects at early stages of the production process, which reduces the costs of fixing them in later stages of the development cycle.
  • Unit tested code is generally safer to refactor because tests can be re-run quickly to validate that behavior hasn't changed.
  • Writing unit tests forces developers to consider how well the production code is designed to make it suitable for unit testing. Developers gain a different perspective that encourages them to consider corner cases and error conditions in their implementation.
  • Including unit tests in the code review process can reveal how the modified or new code is supposed to work. Plus, reviewers can confirm whether the tests are good or not.

With automated testing tools, developers can reduce late-cycle defects with better unit tests and automated static code analysis. They can focus more time on new feature development for the business. Developers also benefit from immediate feedback. They're able to rapidly identify whether their code changes are breaking functionality in the application and address issues quickly.
