A test case usually contains a single step or a sequence of steps to test the correct behavior/functionality and features of an application. An expected result or expected outcome is usually given. Additional information that may be included: [7] Test case ID - A unique identifier for the test case. Description/summary - The test case objective.
A test case graph illustrates all the necessary independent paths (test cases) to cover all isolated conditions. Conditions are represented by nodes, and condition values (situations) by edges. An edge addresses all program situations. Each situation is connected to one preceding and successive condition.
The minimum number of test cases is the number of classes in the classification with the most containing classes. In the second step, test cases are composed by selecting exactly one class from every classification of the classification tree. The selection of test cases originally [3] was a manual task to be performed by the test engineer.
These test cases are derived through the use of the design techniques mentioned above: control flow testing, data flow testing, branch testing, path testing, statement coverage and decision coverage as well as modified condition/decision coverage. White-box testing is the use of these techniques as guidelines to create an error-free environment ...
Because no more code is written than necessary to pass a failing test case, automated tests tend to cover every code path. For example, for a TDD developer to add an else branch to an existing if statement, the developer would first have to write a failing test case that motivates the branch. As a result, the automated tests resulting from TDD ...
A model describing a SUT is usually an abstract, partial presentation of the SUT's desired behavior. Test cases derived from such a model are functional tests on the same level of abstraction as the model. These test cases are collectively known as an abstract test suite. An abstract test suite cannot be directly executed against an SUT because ...
The result of the test design is a set of test cases based on the specification. These test cases can be designed prior to the implementation starts, and should be implementation-independent. Test first way of test design is very important as efficiently supports defect prevention. Based on the application and the present test coverage further ...
Process steps for a happy path are also used in the context of a use case. In contrast to the happy path, process steps for alternate flow and exception flow may also be documented. [3] Happy path test is a well-defined test case using known input, which executes without exception and produces an expected output. [4]
