Java Unitary tests

Since Scilab 5.3.0 beta1, it is possible to write and launch Java Unitary tests from the source code.

What is a unitary tests ?

Unitary tests are small tests on a class which check the behavior of a method. The Java unitary test system is provided by TestNG.

Where to write tests

Tests must be written per module. They must be stored in:


Any Java file in this directory will be built and executed by the test system.

To ease coherence on the scilab platform, use the org.scilab.tests.modules.<module_name> as a root namespace for your tests. Place them accordingly to the source namespace (eg org.scilab.tests.modules.xcos.utils for testing org.scilab.modules.xcos.utils.* classes).

How to launch tests

ant test

will launch Java Unitary tests and provide a report. Note that any error will stop the build process.


The HDF5 modules is tested.
