Pyunit源码笔记之十一 pyunit运行方式之二：testsuit方式

这种方法，先要组建testsuit，实例化testsuit，加入testcase，或者包含其他的testsuit

针对下面的用例：

class MyTest(unittest.TestCase):
def setUp(self):
print("Set up...")
self.myclassa = MyClassA.MyClassA()

def testsum(self, a = 4, b = 5):
self.assertEqual(self.myclassa.addMy(a, b), a * b)

def testmul(self, a = 4, b = 5):
self.assertEqual(self.myclassa.mulMy(a, b), a * b)

def tearDown(self):
print("Tear down...")
pass

先看testsuit的初始化和加入test：
def __init__(self, tests=()):
self._tests = []
self._removed_tests = 0
self.addTests(tests)

def addTest(self, test):
# sanity checks
if not callable(test):
raise TypeError("{} is not callable".format(repr(test)))
if isinstance(test, type) and issubclass(test,
(case.TestCase, TestSuite)):
raise TypeError("TestCases and TestSuites must be instantiated "
"before passing them to addTest()")
self._tests.append(test)

可以实例化后，再加testcase，最后run:
ts = unittest.TestSuite()
ts.addTest(MyTest("testsum"))
ts.addTest(MyTest("testmul"))
其他相似的组建testsuit方式:

def suite():
suite = unittest.TestSuite()
suite.addTest(MyTest("testsum"))
suite.addTest(MyTest("testmul"))
return suite

def suite():
tests = ['testsum', 'testmul']
return unittest.TestSuite(map(MyTest, tests))

利用unittest的TestLoader生成默认的testsuit

ts = unittest.TestLoader().loadTestsFromTestCase(MyTest)多个testsuit组成更大的testsuit:
ts1 = unittest.TestSuite([MyTest("testsum"),])
ts2 = unittest.TestSuite([MyTest("testmul"),])
ts = unittest.TestSuite([ts1, ts2])
最后run:

runner = unittest.TextTestRunner()
runner.run(ts)
