Traceability between individual requirements and their corresponding test cases enables us to analyze the impact of changes to requirements on the testing process (for example, designing new test cases, discarding redundant test cases, or modifying existing test cases). It also enables you to define a degree of coverage as an exit criterion for dynamic testing. In…

Starting at the test basis (i.e., the general test conditions), you need to analyze which aspects of the system require dynamic testing (for example, correct execution of a transaction). The objectives for verifying fulfillment of system requirements through test cases are then defined, with particular attention paid to the risks involved if the system should…

Dynamic testing involves the following steps: These steps can be executed in an informal, undocumented fashion or, as described here, formally. The degree of formality of the process depends among other factors on the planned system usage (for example, safety-critical), the maturity of the development and test processes, time constraints, and the skills of the…

The test objective is to verify that the specified requirements are fulfilled by the implemented component, and to identify any failures or deviations from the requirements. The objective is to use as little effort as possible to test as many requirements and identify as many failures as possible. To achieve this objective, you need to…

The test framework also provides the test object with input data, which usually requires simulation of the component that calls the test object. This task is performed by a test driver. The test driver and the stubs make up the test framework that, together with the test object, forms an executable program. The test framework…

The test object will usually use predefined interfaces to call other components, which are simulated by placeholders called stubs or mocks if the components themselves are not yet ready. Stubs simulate the input/output behavior of the components they represent.

When we talk about software testing, most people imagine that it involves running a program on a computer. The term “dynamic testing” helps to clarify the situation. The test object has to be executable and is fed with input data before it is run. Because low-level test objects (component and integration tests) are not usually…

Describes the process of testing software by running it on a computer. It uses examples to illustrate various ways to specify test cases and exit criteria. Dynamic testing is based on black-box, white-box, and experience-based techniques. We explain what each category means and how to choose the appropriate one for your situation.
