Using a white-box approach, each program specification is analyzed to identify the distinct logic paths which serve as the basisįor unit test design. Since most business applications combine approaches, an example combining black- and white-box strategies is described here. Examples of application damage might include life-threatening situations such as in nuclear power plant support systems, life support systems in hospitals, or test systems for car or plane parts. For example, organizationally critical processes might be defined as any process that affects the financial books of the organization' meets legal requirements, or deals Possible errors, the more detailed and extensively white-box testing is used. In general, the more critical to the organization or the more damaging the For process logic, either or both strategies can be used. For input/output bound applications, black-box strategies are normally used. There is no one strategy for unit testing. ![]() Outputs might include hard copy, terminal displays, electronic transmissions, or file contents all are tested. Third, all output should be consistent with results predicted from the specification. Second, all possible errors should be found and treated according to First, each module must process all allowable types of input data in a stable, predictable, and accurate manner. Processing accuracy has three components: input, process, and output. The test is designed/rom the specification, not the code. The logical and operational requirements of each module are taken from the program specifications. To specifications and processing accuracy.įor conformance, unit tests determine the extent to which processing logic satisfies the functions assigned to the module. The two primary goals of unit testing are conformance Unit tests verify that a specific program, module, or routine (all referred to as 'module' in the remaining discussion) fulfills its requirements as stated in related program and design specifications. ![]()
