用法

classPerson:def__init__(self,name,age,favorites):self.name=nameself.age=ageself.favorites=favoritesdeftest_person():a=Person("Alice",age=21,favorites={"food":"spam","movie":"Life of Brian"})b=Person("Alice",age=21,favorites={"food":"eggs","movie":"Life of Brian"})asserta==b

运行pytest给出：

______________________________test_person______________________________deftest_person():a=Person("Alice",age=21,favorites={'food':'spam','movie':'Life of Brian'})b=Person("Alice",age=21,favorites={'food':'eggs','movie':'Life of Brian'})>asserta==bEassertE<test_person.Personobjectat0x7fa326d769e8>E==E<test_person.Personobjectat0x7fa326d76be0>E{'values_changed':{"root.favorites['food']":{'new_value':'spam','old_value':'eggs'}}}examples/test_person.py:11:AssertionError

要为特定类型自定义diff，请在注册表中注册：

importpytest_diffclassCar:def__init__(self,make,model,year):self.make=makeself.model=modelself.year=year@pytest_diff.registry.register(Car)defdiff(x,y):return[f"{x.make} vs {y.make}",f"{x.model} vs {y.model}",f"{x.year} vs {y.year}",]deftest_car():c1=Car("Toyota","Prius",2010)c2=Car("Honda","Accord",2009)assertc1==c2

然后运行pytest显示您的自定义差异：

deftest_car():c1=Car("Toyota","Prius",2010)c2=Car("Honda","Accord",2009)>assertc1==c2EassertE<test_custom.Carobjectat0x7f0e9b0ccd68>E==E<test_custom.Carobjectat0x7f0e9b0cceb8>EToyotavsHondaEPriusvsAccordE2010vs2009examples/test_custom.py:21:AssertionError
