armi.reactor.blueprints.tests.test_customIsotopics module

Unit test custom isotopics.

class armi.reactor.blueprints.tests.test_customIsotopics.TestCustomIsotopics(methodName='runTest')

Bases: unittest.case.TestCase

Create 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.
