The Spoofax Testing Language (SPT) allows you to test your DSLs. See http://www.metaborg.org/spt for documentation on SPT.
Note that on this branch we are doing an overhaul of SPT, so many features won't work yet.
SPT is a Spoofax language just like any other. At the moment it's still only a very limited version of what it should be and it doesn't have an Eclipse project yet. The language specification can be found in org.metaborg.meta.lang.spt.
SPT Core is our attempt at extracting the core functionality of SPT into a Java API. The project is located at org.metaborg.spt.core.
The idea is that you can extract tests from a testsuite into an ITestCase.
This is done by the ITestExtractor.
These test cases can then be run using the ITestRunner.
Both the extractor and the runner can be registered and obtained using Google Guice.
See the Module class in org.metaborg.spt.cmd to see how that is done.
See the Runner class in org.metaborg.spt.cmd to see how they are used.
To keep the test expectations of SPT modular,
they too can be injected using Guice.
See the ParseExpectationTest class in org.metaborg.spt.cmd to see an example for the parse succeeds expectation.
The command line interface can currently run test suites.
It won't print any results yet, but they can be checked using the logs.
See Main and Arguments in org.metaborg.spt.cmd to learn about the usage of this tool.
