我有这个测试
import unittest
class TestName(unittest.TestCase):
def setUp(self):
self.name = "Bob"
self.expected_name = "Bob"
def test_name(self):
# ... some operation over self.name
print self.name
self.assertEquals(self.name, self.expected_name)
if __name__ == '__main__':
unittest.main(verbosity=2)
我如何运行测试实例?
对输入和输出列表(["Bob", "Alice", ...]
)运行相同的测试,可能像
TestName(name="Bob", expected_name="Bob")
TestName(name="Alice", expected_name="Alice")

查看DDT (Data-Driven/Decorated Tests)。
DDT允许您通过使用不同的测试数据运行测试用例来使其成倍增加,使其显示为多个测试用例。
考虑这个例子,使用DDT:
import unittest
from ddt import ddt, data, unpack
@ddt
class TestName(unittest.TestCase):
# simple decorator usage:
@data(1, 2)
def test_greater_than_zero(self, value):
self.assertGreater(value, 0)
# passing data in tuples to achieve the
# scenarios from your given example:
@data(('Bob', 'Bob'), ('Alice', 'Alice'))
@unpack
def test_name(self, first_value, second_value):
name, expected_name = first_value, second_value
self.assertEquals(name, expected_name)
if __name__ == '__main__':
unittest.main(verbosity=2)
我在上面的代码中定义了2个测试方法,但是将使用装饰器中提供的数据运行4个测试用例。
输出:
test_greater_than_zero_1 (__main__.TestName) ... ok
test_greater_than_zero_2 (__main__.TestName) ... ok
test_name_('Alice', 'Alice') (__main__.TestName) ... ok
test_name_('Bob', 'Bob') (__main__.TestName) ... ok

Ran 4 tests in 0.000s
OK

我会在这里使用mixin或元类,因为unittest会查找类,而不是实例。
class TestMixin (object):
def test_name ():
print self.name
class TestName (unittest.TestCase, TestMixin):
...
