Functional testing, or integration testing, is concerned with the entire system, not just small pieces (or units) of code. It involves taking features that have been tested independently, combining them into components, and verifying if they work together as expected. For Java, this testing is typically performed using the JUnit framework. Most Java developers are well-versed in logistical test construction matters, such as how to develop a test fixture, add test methods with assertions, use the setup method for initialization, and so forth. However, many Java developers could benefit from a deeper understanding of how to develop a functional test suite that effectively verifies whether code works as designed. This article introduces and demonstrates the following strategy for building an effective JUnit functional test suite: Identify use cases that cover all acti... (more)

There are three main types of software bugs: • Poorly implemented requirements - The software doesn't operate as expected because the functionality defined in the requirements was implemented incorrectly. • Missing or incomplete requirements - The software doesn't perform necessary operations or handle feasible scenarios because the stakeholders/designers didn't anticipate the need for such functionality and didn't specify requirements for it, or because the developers failed to implement a specified requirement. • Confused user - The software was designed in a way t...
