armi.reactor.blueprints.tests.test_customIsotopics module
Unit test custom isotopics.
- class armi.reactor.blueprints.tests.test_customIsotopics.TestCustomIsotopics(methodName='runTest')[source]
Bases:
TestCaseCreate an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.
