Python pytest 模块，inlineCallbacks() 实例源码
我们从Python开源项目中，提取了以下3个代码示例，用于说明如何使用pytest.inlineCallbacks()。
def test_io_validate_list(self, instance, classroom_model):
Student = classroom_model.Student
called = []
values = [1, 2, 3, 4]
@inlineCallbacks
def io_validate(field, value):
yield called.append(value)
@instance.register
class IOStudent(Student):
io_field = fields.ListField(fields.IntField(io_validate=io_validate))
student = IOStudent(name='Marty', io_field=values)
yield student.io_validate()
assert called == values
def test_pre_post_hooks_with_defers(self, instance):
events = []
@instance.register
class Person(Document):
name = fields.StrField()
age = fields.IntField()
@inlineCallbacks
def pre_insert(self):
events.append('start pre_insert')
yield succeed
events.append('end pre_insert')
@inlineCallbacks
def post_insert(self, ret):
events.append('start post_insert')
yield succeed
events.append('end post_insert')
p = Person(name='John', age=20)
yield p.commit()
assert events == [
'start pre_insert',
'end pre_insert',
'start post_insert',
'end post_insert'
]
def test_io_validate_multi_validate(self, classroom_model):
Student = classroom_model.Student
called = []
defer1 = Deferred()
defer2 = Deferred()
defer3 = Deferred()
defer4 = Deferred()
@inlineCallbacks
def io_validate11(field, value):
called.append(1)
defer1.callback(None)
yield defer3
called.append(4)
defer4.callback(None)
@inlineCallbacks
def io_validate12(field, value):
yield defer4
called.append(5)
@inlineCallbacks
def io_validate21(field, value):
yield defer2
called.append(3)
defer3.callback(None)
@inlineCallbacks
def io_validate22(field, value):
yield defer1
called.append(2)
defer2.callback(None)
@instance.register
class IOStudent(Student):
io_field1 = fields.StrField(io_validate=(io_validate11, io_validate12))
io_field2 = fields.StrField(io_validate=(io_validate21, io_validate22))
student = IOStudent(name='Marty', io_field1='io1', io_field2='io2')
yield student.io_validate()
assert called == [1, 4, 5]
