Chapter 12. Testing and Monitoring Concurrent Applications

Software testing is a critical task in every development process. Every application has to fulfill end user requirements, and the testing phase is the place to prove this. It has to generate valid results in an acceptable time and with the specified format. The main objective of the testing phase is to detect as many errors as possible in the software to correct them and increase the global quality of the product.

Traditionally, in the waterfall model, the testing phase begins when the development phase is very advanced, but nowadays, more and more development teams are using agile methodologies, where the testing phase is integrated into the development phase. The main objective is to test the software as soon as possible to detect errors earlier in the process.

In Java, there are a lot of tools, such as JUnit or TestNG, to automatize the execution of tests. Other tools, such as JMeter, allow you to test how many users can execute...
