Composing Tests from Examples
Understanding and maintaining complex software systems is a difficult task. In principle, tests can be a good source of information about how the system works. Unfortunately, tests are frequently unstructured and disconnected from each other and from their units under test. We propose a new approach to organizing unit tests in which tests produce examples of their units under tests which also c...
متن کاملComposing Unit Tests
1 If we were to apply the testing techniques of object-oriented systems prescribed by the XUnit framework to a car factory, the result would be an inefficient process: A tire would be created, quality assured and then thrown away, only to be recreated later to test the functionality of the whole car. XUnit makes it difficult to reuse intermediate results of low level unit tests. As a consequenc...
متن کاملReusing and Composing Tests with Traits
Single inheritance often forces developers to duplicate code and logic. This widely recognized situation affects both business code and tests. In a large and complex application whose classes implement many groups of methods (protocols), duplication may also follow the application’s idiosyncrasies, making it difficult to specify, maintain, and reuse tests. The research questions we faced are (i...
متن کاملAssessing the robustness of randomization tests: examples from behavioural studies.
Behavioural studies are commonly plagued with data that violate the assumptions of parametric statistics. Consequently, classic nonparametric methods (e.g. rank tests) and novel distribution-free methods (e.g. randomization tests) have been used to a great extent by behaviourists. However, the robustness of such methods in terms of statistical power and type I error have seldom been evaluated. ...
متن کاملMoran–Flavoured Tests with Nuisance Parameters: Examples
In this paper I illustrate the use of general conditions, derived by Pinkse (1999), under which Moran–flavoured tests for spatial correlation and spatial cross–correlation have a limiting normal distribution in the presence of nuisance parameters in six frequently encountered spatial models. The conditions are weaker than those in related work by other authors and the class of nuisance paramete...
