TPT

TPT (Time Partition Testing) is a testing tool designed for software testing and validation. According to PikeTec GmbH, the vendor of TPT, it supports various testing levels, including Model-in-the-Loop (MiL), Software-in-the-Loop (SiL), and Processor-in-the-Loop (PiL) testing. TPT is used by professionals in industries such as automotive, aerospace, defense, and industrial automation. The tool caters to small to large companies and offers a range of features to enhance the testing process.

Key Features

Signal Viewer: According to the vendor, TPT provides a Signal Viewer that allows users to graphically analyze test data in detail. The Signal Viewer offers features such as zoom, view scaling, multi-windowing, and display configuration management. Users can also utilize multiple cursors and difference displays for enhanced analysis.

Dashboard: TPT offers a Dashboard feature that enables users to create customized interfaces for interacting with the system under test. According to the vendor, the Dashboard provides real-time visual feedback and allows users to easily create graphical user interfaces tailored to their testing needs.

Define expected values in test cases: TPT allows users to specify expected values directly in test cases, including tolerance specifications. According to the vendor, this feature enables precise validation of test results against predefined expectations.

Regression tests and back-to-back tests: TPT supports the comparison of test results from multiple test executions, aiding in the identification of changes in software behavior. The vendor claims that this feature facilitates efficient regression testing and back-to-back testing to ensure software stability and consistency.

Assess tests rule-based with assesslets: TPT provides pre-defined graphical forms, known as assesslets, for rule-based test assessment. According to the vendor, users can specify expectations on signal behavior, include conditions, and account for test phase dependencies in the assessment process.

Check value ranges: According to the vendor, TPT offers the Min/Max Comparison assesslet to check if a signal lies within a predefined value range. This feature helps ensure that signals are within the expected boundaries.

Compare signals: TPT includes the Signal Comparison assesslet, which allows users to compare one or more signals. According to the vendor, users can define absolute, relative, or temporal tolerances for signal comparison. Tolerances can also depend on signal scaling, providing flexibility in the assessment process.

Check equivalence classes: TPT provides the Equivalence Classes assesslet to inspect if tests cover all defined equivalence classes. According to the vendor, this feature generates a statistical overview of equivalence class coverage, ensuring comprehensive test coverage.

Check causal rules: The Trigger Rule assesslet in TPT enables users to check if-then rules with temporal and logical conditions. According to the vendor, users can activate or deactivate checks based on specific conditions and set restrictions in time and stop criteria.

Check sequences: TPT offers the Sequence Check assesslet to inspect consecutive phases based on signal characteristics. The vendor claims that this feature allows users to verify specific sequences in the system under test.
