ludibrio Description

Platform for test doubles in Python (mocks, stubs, fakes, and dummies) ludibrio is a platform to test doubles in Python (mocks, stubs, fakes, and dummies).MocksMocks are what we are talking about here: objects pre-programmed with expectations which form a specification of the calls they are expected to receive. >>> from ludibrio import Mock >>> with Mock() as greetings: ... greetings.excuse_me() >> 'Com licença' ... greetings.hello('Gustavo') >> 'Ola, Gustavo' ... greetings.see_you_soon >> 'Até logo' ... greetings.see_you_soon >> 'Até logo, denovo' >>> print greetings.excuse_me() Com licença >>> print greetings.hello('Gustavo') Ola, Gustavo >>> print greetings.see_you_soon Até logo >>> print greetings.see_you_soon Até logo, denovo >>> print greetings.see_you_soon Traceback (most recent call last): ... AssertionError: Object's mocks are not pre-programmed with expectations >>> with Mock() as greetings: ... greetings.excuse_me() >> 'Com licença' ... greetings.see_you_soon >> 'Até logo' >>> print greetings.excuse_me() Com licença >>> print greetings.hello('Gustavo Rezende') Traceback (most recent call last): ... AssertionError: Object's mocks are not pre-programmed with expectations: __getattribute__(see_you_soon, ) Expected: __getattribute__(hello, ) >>> with Mock() as greetings: ... greetings.excuse_me(name='gustavo') >> 'Com licença' >>> greetings.excuse_me(name='Diego Manhães') Traceback (most recent call last): ... AssertionError: Object's mocks are not pre-programmed with expectations: __call__(, name=gustavo) Expected: __call__(, name=Diego Manhães) >>> with Mock() as listing: ... listing >> 'um' ... listing >> ... listing >> 4 >>> print listing um >>> print listing >>> print listing 4 >>> with Mock() as callable: ... callable(two=2) >> 2 >>> callable(two=2) 2 >>> with Mock() as operator: ... operator * 4 >> 4 ... operator + 4 >> 5 ... operator ** 4 >> 1 >>> operator * 4 4 >>> operator + 4 5 >>> operator ** 4 1 >>> with Mock() as Greetings: ... greetings = Greetings(tree=3) >>> greetings Mock Object >>> with Mock() as MySQLdb: ... con = MySQLdb.connect('servidor', ' usuario', 'senha') ... con.select_db('banco de dados') >> None ... cursor = con.cursor() ... cursor.execute('ALGUM SQL') >> None ... cursor.fetchall() >> >>> con = MySQLdb.connect('servidor', ' usuario', 'senha') >>> con.select_db('banco de dados') >>> cursor = con.cursor() >>> cursor.execute('ALGUM SQL') >>> cursor.fetchall() >>> with Mock() as testeError: ... testeError.foo('bar') >> ArithmeticError('teste error') >>> testeError.foo('bar') Traceback (most recent call last): ...
