Practicality Whether a test is practical or not is related to the resource demands of the test set against the available resources (Bachman and Palmer, 1996) and is considered an essential criteria contributing to its success. At the development stage it is common for a test to exceed available resources, but in the long run if a test exceeds the resources that it has available then it will inevitably be deemed unsuccessful. Bachman and Palmer provide a list of the different types of resources to consider in testing.
