Comparative Study of Test Driven Development with Traditional Techniques
نویسندگان
چکیده
Test-Driven Development is the evolutionary approach in which unit test cases are incrementally written prior to code implementation. In our research, we will be doing comparative study of Test Driven development with traditional techniques through literature study as well as industrial survey. Through this research, we would like to find out the factors encouraging the use of Test Driven Development and also the obstacles that are limiting the adoption of Test Driven Development in the industry. The TDD method is radically different from the traditional way to create software. In traditional software development models, the tests are written after the code is implemented, in other words we could refer it as test-last. This does not drive the design of the code to be testable. Defining the tests with the requirements, rather than after, and using those tests to drive the development effort, gives us much more clearly picture and share focus on the goal. If tests are written after the implementation, there is a risk that tests are written to satisfy the implementation, not the requirements. An important rule in TDD is: “If you can’t write test for what you are about to code, then you shouldn’t even be thinking about coding.” Keywordsextreme programming, refactoring, test driven development, test-first methodology, test-last methodology.

متن کاملDoes Test-Driven Development Improve the Program Code? Alarming Results from a Comparative Case Study
It is suggested that test-driven development (TDD) is one of the most fundamental practices in agile software development, which produces loosely coupled and highly cohesive code. However, how the TDD impacts on the structure of the program code have not been widely studied. This paper presents the results from a comparative case study of five small scale software development projects where the...
