Automatic test cases generation
Automatic test case generation can ease the testing and optimize the test coverage with minimal effort. With TPT, test cases can be generated in different ways. The methods range from simple combinatorics to sophisticated methods to fulfill the aim of structural coverage of test objects.
Coverage of MATLAB/Simulink and TargetLink models (TASMO)
TASMO finds the smallest amount of test cases to achieve the most comprehensive structural coverage possible. For this purpose, TASMO uses an unique combination of evolutionary algorithms and static analysis.
Coverage of Equivalence Classes
TPT enables you to generate test cases that cover equivalence classes.
Test case generation from measurement files
TPT can import more than one measurement file at once. For each file a test case is generated. The following file formats are supported: *.csv, *.dat, *.mat, *.mf4, *.mdf, *.tptbin, and *.xls.
Coverage of Value Ranges
For selected output signals, TPT can generate test cases that cover specified value ranges.
Combinatorial test cases
TPT is able to generate test cases by combining user-selected variants of states, transitions, and paths of an automaton.
Test cases by analyzing MATLAB/Simulink and TargetLink models (TASMO)
TASMO generates test data by analyzing MATLAB/Simulink or TargetLink models. It finds the smallest amount of test cases to achieve the most comprehensive structural coverage (Condition Coverage, Decision Coverage) for the model possible. TASMO uses a unique combination of statistical analysis and evolutionary algorithms to fulfill its task.
Due to efficient methods, TASMO can even generate test cases for the coverage of complex models. TASMO supports all commonly known block types, systems with feedback, Stateflow models, structured signals, and many more.
Among other things, the test cases generated by TASMO can be used to run back-to-back tests and regression tests to meet the requirements of safety standards like ISO 26262.
Test cases from Equivalence Classes
TPT supports the definition of equivalence classes sets consisting of several equivalence classes. Based upon the selected equivalence classes from one or several sets,
the test cases are generated automatically. This is done by combination of automatically determined or user-specified representatives of the equivalence classes that are used as input signals to the system to be tested.
The structure and the range of the coverage of equivalence classes is easy to configure.
Moreover, TPT enables you to check and document automatically the coverage of the equivalence classes.
Test cases by combining variants of states, paths, and transitions
A TPT model consists of a so-called automaton that contains variants of its states and transition conditions. Furthermore, test cases can be modeled by choosing different paths in the respective TPT-automaton. In general, in TPT test cases are built upon combinations of different variants. These test cases can be specified manually by the user and can also be generated automatically according to configurable settings. In the settings, the user chooses the state, transition, and path variants of an automaton that should be used for the test case generation.
Coverage of Value Ranges
TPT can generate test cases that contain all permutations of values for output channels.
The values can be derived from a mapping. You can select the signals that should be used for the test case generation, and change the minimum and maximum values and also a quantization for each signal manually.
