COTT – A Testability Framework for Object-Oriented Software Testing
نویسندگان
چکیده
Testable software has two inherent properties – observability and controllability. Observability facilitates observation of internal behavior of software to required degree of detail. Controllability allows creation of difficult-to-achieve states prior to execution of various tests. In this paper, we describe COTT, a Controllability and Observability Testing Tool, to create testable object-oriented software. COTT provides a framework that helps the user to instrument object-oriented software to build the required controllability and observability. During testing, the tool facilitates creation of difficult-to-achieve states required for testing of difficultto-test conditions and observation of internal details of execution at unit, integration and system levels. The execution observations are logged in a test log file, which are used for post analysis and to generate test coverage reports. Keywords—Controllability, Observability, Test Coverage and Testing Tool.

Testability Estimation of Framework Based Applications
Quality of software systems is highly demanded in today’s scenario. Highly testable system enhances the reliability also. More than 50% of test effort-time and cost are used to produce a highly testable system. Thus, design-for-testability is needed to reduce the test effort. In order to enhance the quality, productivity and reduced cost of the software organizations are promoting to produce th...
متن کاملA measurement framework for object-oriented software testability
As software applications grow more complex and become a necessity in almost everyday activities, more emphasis has been placed on software quality and reliability. Effective testing is therefore required to achieve adequate levels of software quality and reliability. However, we are facing a dilemma: software systems are growing in complexity and testing resources are by definition limited. To ...
متن کاملTestability Models for Object-Oriented Frameworks
Frameworks are time-tested highly reusable architectural skeleton structures. They are designed ‘abstract’ and ‘incomplete’ and are designed with predefined points of variability, known as hot spots, to be customized later at the time of framework reuse. Frameworks are reusable entities thus demand stricter and rigorous testing in comparison to onetime use application. The overall cost of frame...
متن کاملImproving the Testability of Object-oriented Software during Testing and Debugging Processes
Testability is the probability whether tests will detect a fault, given that a fault in the program exists. How efficiently the faults will be uncovered depends upon the testability of the software. Various researchers have proposed qualitative and quantitative techniques to improve and measure the testability of software. In literature, a plethora of reliability growth models have been used to...
متن کاملDesign for Testability
Testability is a software quality characteristic that is of major relevance for test costs and software dependability. Still, testability is not an explicit focus in today’s industrial software development projects. Related processes, guidelines, and tools are missing. This paper is about design for testability, the main intersection of software design and testing. We describe 1) elements of ob...
