When explicitly considering the testability of software-centric systems, architects tend to be more conscious and thoughtful about their design decisions, be they related to modularization, interfaces, or design choices. The paper discusses how architects can use tests and test-driven development as a design tool. The goal is to avoid or discover architectural deficiencies before they're realized-when...
The eXtreme Programming (XP) software development methodology has received considerable industrial attention in recent years. As a methodology which is highly responsive to customer's changing requirements, XP has been widely used in Web application developing process. As a key characteristic of XP, Test-Driven Development(TDD) can be used for refactoring the new code and ensuring the quality of the...
Test-driven development (TDD) - an established approach in business IT software development - enables test case generation based on models early in the development process. Applying TDD and models in automation systems engineering (ASE) can increase testing effectiveness and efficiency. A key question is which models are suitable for ASE application. UML models support software and systems engineering...
Instituting an automated unit testing practice across a large software development team can be technically challenging and time consuming. As a result, teams may question the economic value of instituting such a practice. One large Microsoft team consisting of 32 developers transitioned from ad hoc and individualized unit testing practices to the utilization of the NUnit automated unit testing framework...
Research and practice show that a large number of Web services are deployed with robustness problems (i.e., presenting unexpected behaviors in the presence of invalid inputs). Test-driven development, particularly suitable for Web service environments, is a software development technique based on predefined test cases that are used during development to validate the desired software improvements or...
This paper suggests a holistic design and development method combining test-driven and model-driven development for SOA architectures. It uses test-driven development on component level and model-based testing on system level. Moreover, monitored performance parameters during test execution serve as input for a model-driven performance analysis of the business application, providing early indication...
The key factor of component based software development is component composition technology. Although many researches have focused on this subject, the quality of system that is composed of components has not been guaranteed indubitably. Test-driven development (TDD) is a software development methodology for achieving high reliability. The combination of these two technologies will help to locate the...
