  • msg – A context string explaining why this assertion was done.
assert_true(obj, msg)

Assert obj is True.

Wrapper on unittest’s assertTrue

Parameters:
  • obj – Object of any type

class arjuna.tpi.engine.asserter.AsserterMixIn

Bases: object

Base class to add asserter property to any class which inherits from it.

asserter

Arjuna’s Asserter object for executing assertions.

class arjuna.tpi.engine.asserter.IterableAsserterMixin

Bases: object
