Usage of ATDD in Java projects
Many in the Java projects community wonder whether ATDD really helps one to save time. The full form of ATDD is Acceptance Test Driven Development. This is indeed an effective development practice.Have a look at these small projects in java
to understand better. It involves writing down specifications which are in the form of documented as well as automated examples. The automated examples in turn become acceptance tests that are automated. These help to validate the features that are being delivered by a program. When a team works on the process of writing such examples, it forces them to focus on the business value of the features involved. That in turn allows developers to seek out the right solution which is appropriate in terms of business sense. Many Java developers work with ATDD as well as TDD practices. At that time they encounter a common question. Is more development time being used up in using ATDD?
Those developers involved in Java projects who use Acceptance Test Driven Development and write automated tests, spend more time in development when compared to projects executed without any automated testing. However, when it comes to TDD, the developers who are experienced in its usage take more or less the same time to implement codes that are written without the use of TDD.
However, those who adopt and practice ATDD norms in testing usually deliver projects that have fewer defects and are also checked faster than other projects. This can be clarified by certain examples. When one is writing specifications to be included in automated test the requirements are clarified earlier than later. Also the style of reporting in ATDD makes the deliverable of a project visible much earlier. This in turn allows development to be focused on the building features. That in turn provides real value and reduces waste in terms of development time and resources.
