Note that the SBML Test Suite test cases can be used without the Test Runner – the runner is just a convenient automation framework for running multiple tests. The SBML Test Runner currently only supports the semantic tests of the test suite it does not yet support running applications through the stochastic or syntactic tests. The image below shows an example run from the SBML Test Runner: If you have downloaded a precompiled release of the SBML Test Runner, it will come complete with the test cases already included, and it can automatically check for updates to the test cases. The SBML Test Runner can be used to run an application against the collection of semantic test cases in the Test Suite, and report successes and failures. This allows the tests to be used by software tools that can only handle certain SBML Levels/Versions it also allows the assessment of software tools’ handling of different Levels and Versions. Test models in the semantic and stochastic test sets are provided in multiple SBML Level + Version combinations. Because the expected results are stochastic, each test case is designed to be performed multiple times, with summary statistics collected for each, which are then compared to the expected summary statistics using a formula derived from the number of times the test was repeated. Each test consists of a directory containing the model together with instructions on how to simulate that model, and the expected results. Some of the models are intended to test the accuracy of systems that employ discrete stochastic simulation algorithms others test the implementation of the SBML Level 3 Distributions Package. Each test requires simulating the model multiple times. Stochastic: The stochastic test suite contains valid SBML models with known simulation results. Each test consists of a model together with instructions on how to simulate that model, and the expected results. An example of a deterministic simulator is one that uses a differential-algebraic equation solver with the ability to handle discontinuous events. These test cases can be used to test the ability of a software system to understand the meaning of different SBML constructs and properly simulate the models in a deterministic fashion. Where possible and practical, the expected numerical values have been produced using analytical solution methods. ![]() Each test requires simulating the model once. Semantic: The semantic test suite contains valid SBML models with known, deterministic simulation results. ![]() Details about the error and the error message produced by libSBML are included with each test case description, as are incidental warnings that libSBML may also produce for a given model/test case. Each model in this part of the Test Suite is expected to be recognized by a software system as being either valid or invalid. The validation rules are defined in the SBML specification documents. Each test is designed to check a particular SBML syntactic validation rule there are no simulations involved in these tests. Syntactic: The syntactic test suite consists of valid and invalid SBML models. Each tests a different aspect of SBML understanding and compliance. The SBML Test Suite test cases are divided into 3 sets and distributed separately. It can be used by developers to test their software’s implementation of SBML support it can also be used by modelers to assess the correctness and completeness of SBML support in a given software system. The SBML Test Suite is a conformance testing system for SBML. ![]()
