I've added the preliminary framework for a test suite in relax to test for regressions and the introduction of new bugs. Currently the number of tests is limited. To run the relax test suite, type: $ relax --test-suite Hopefully the framework is simple enough for new tests to be easily added as necessary. The main test suite code is in the file 'test_suite/test_suite.py' while the tests themselves are to be placed in other files in that directory. Tests can be added for any user function, for reproducing new bugs which are reported, or for any other internal operations in relax. Edward
