unnitest是Python的一个重要的单元测试框架，对于用Python进行开发的同事们可能不需要对他有过深入的了解会用就行，但是，对于自动化测试人员我觉得是要熟知unnitest的执行原理以及相关模块的作用。我这边提几个简单的需求如下：
1. 如何利用unnitest执行流程测试而非单元测试 。比如我们可能利用selenium+unnitest来跑 一段流程 ，比如test1里面我们实现登陆，test2在test1成功登陆的基础上，实现一个查询的测试，test3我们查询一些数据后，页面选择性提交数据。这个你总不能在test1里面登陆完然后关闭浏览器；在test2里面再登陆再执行查询后关闭浏览器；test3再登陆执行提交数据。你或者可以这样想把这几个步骤写在一个test里面。但是，如果流程过长怎么办？自己难道感觉不到剪不断理还乱的纠结吗....
2. 如何控制unnitest的执行顺序。 unnitest里面tests数组里面存放的TestCase默认是以首字母排序的，这对于test1,test2....test9这样的执行顺序是没用问题的，但是对于多个test比如test1,test2.........test18,这样unnitest可不是按照这个顺序，我说了是按照首字母排序来的，他会这样执行test1,test10,....test18,test2,..........test9,当然我说的这些对于单元测试是影响不大的(除非各个test之间有数据依赖关系，后面提到)，对于流程可能是颠覆性的。
3.
流程测试中如何动态的控制是否跳过某个test的执行
。对于流程来说，这也是常见的一种想法，比如test1我连登陆都没有成功，还有意义执行后面的test吗，之后报出来的都是一些NosuchElement的错误，这些错误没有任何意义，而且纯粹浪费时间....出来的报告也是不"人性的"。那么我们现在一个好的想法是：如果test1没有执行成功，后面的test能动态全部跳过，其实不止是test1没成功，后面test跳过，准确的说是，test1,test2........testN中如果任意某个test没有通过，后面的能动态的全部跳过。
当然
，如果后面的test和前面test没什么关系，也可能选择不管前面是否成功均不跳过；也可以是只和test1登录有关，只要登录成功了我就不跳过，如果登录不成功我就跳过...还有很多.....更重要的是，报告中有所展现,不能说skip了某个用例，你报告就不显示了，这样老板认为你偷懒，用例写这么少？ 你还要瑟瑟发抖的去解释，是因为前面的用例没通过所以，没显示了...
我们高大上的是这样的，test1执行失败了，test2.......testN,报告中都体现，标注是skip的case，而且点开还有原因解释:"test1没有执行成功，所以跳过此case"。这就是我拓展HTMLTestRunner的原因，后面逐行解释如果拓展它。
.......还有很多
补充一下，为什么往流程上扯呢，因为公司的模块太多，而且复杂，单元测试机会不太会用，只要保证各个业务的主流程没问题即可，但是不影响我们解析unnitest。
我们的想法很多，但是如何来实现呢？那就让我们来深入探讨下python的unnitest吧！
关于unnitest看似复杂我给出来就是 unnitest= TestCase+TestResult ,只要熟知这2个模块，你就能"为所欲为"！！可能有人说不对不是有什么TestSuite吗还有TextTestRunner等等吗，不错确实我们平时用到的大多是这些模块，但是，到其实最终执行的是 TestCase 中的run方法，并把结果给 TestResult (或它的子类)。我们先来看一个简单的unnitest例子，并以此来拓展！例子如下：
import unittest
class Mydemo(unittest.TestCase):
def setUp(self):
self.a=1
def test1(self):
print "i am test1 the value of a is {}".format(self.a)
def test2(self):
print "i am test2 the value of a is {}".format(self.a)
def test3(self):
print "i am test3 the value of a is {}".format(self.a)
if __name__ == '__main__':
unittest.main()
运行结果如下：
i am test1 the value of a is 1
...
i am test2 the value of a is 1
i am test3 the value of a is 1
----------------------------------------------------------------------
Ran 3 tests in 0.000s OK
这个是没有问题的，那么我们可能要想这个unnitest.main()是什么东西，还有其他的写法来执行吗，能只执行test1,test2,不执行test3吗(暂时不用skip)？那么我们从unittest.main()看起来。debug进入其实最终执行的是TestProgram这类，贴出构造函数部分代码：
if argv is None:
argv = sys.argv#得到当前模块的绝对路径 self.exit = exit
self.failfast = failfast
self.catchbreak = catchbreak
self.verbosity = verbosity
self.buffer = buffer
self.defaultTest = defaultTest
self.testRunner = testRunner
self.testLoader = testLoader
self.progName = os.path.basename(argv[0])
self.parseArgs(argv)#查找当前module的Testsuite
self.runTests()#执行测试
好了，从上面我们可以看出来其实也就2个主要的步骤就是第一:找出要测试的testcase，并加入到Testsuite，第二：运行Testsuite并把结果给TestResult。
首先，第一:了解什么是TestCase？什么是TestSuite？第二:如果找出这些Testcase,或者TestSuite？
什么是TestCase？
有人说TesetCase就是以test开头的就叫一个testcase，我只能这样说太偏面的， 准确的说：是实例了一个TesetCase类的叫一个TestCase ，比如这样：
import unittest
class Mydemo(unittest.TestCase):
def setUp(self):
self.a=1
def Mytest1(self):
print "i am Mytest1 the value of a is {}".format(self.a)
def Mytest2(self):
print "i am Mytest2 the value of a is {}".format(self.a)
def Mytest3(self):
print "i am Mytest3 the value of a is {}".format(self.a)
if __name__ == '__main__':
test_runner=unittest.TextTestRunner()
test_suit=unittest.TestSuite()
test_suit.addTests(map(Mydemo,["Mytest1","Mytest2","Mytest3"]))
test_runner.run(test_suit)
运行结果如下：
...
i am Mytest1 the value of a is 1
----------------------------------------------------------------------
i am Mytest2 the value of a is 1
Ran 3 tests in 0.000s
i am Mytest3 the value of a is 1 OK
上面3个Testcase可并没有以test开头...那么为什么大家都要默认以test开头来写呢，我们打开C:\Python27\Lib\unittest\loader.py这个模块在296行有写defaultTestLoader = TestLoader()，我们来看看TestLoader这个类第一行就看见testMethodPrefix = 'test'，也就是说如果你使用到defaultTestLoader，那么默认是以test开头的方法为一个用例，具体可以在TestLoader类中的getTestCaseNames得到实现,红字注释部分为什么testCaseClass要有__call__方法，我们后面提到。（不知道__call__这个魔法属性的用法自行百度）
def getTestCaseNames(self, testCaseClass):
"""Return a sorted sequence of method names found within testCaseClass
"""
def isTestMethod(attrname, testCaseClass=testCaseClass,
prefix=self.testMethodPrefix):
return attrname.startswith(prefix) and \
hasattr(getattr(testCaseClass, attrname), '__call__')#返回一个testCaseClass有__call__方法且attrname以prefix开头的为一个testcase
testFnNames = filter(isTestMethod, dir(testCaseClass))
if self.sortTestMethodsUsing:
testFnNames.sort(key=_CmpToKey(self.sortTestMethodsUsing))
return testFnNames
原来是这样啊，我们上文提到的unittest.main()其实用的就是defaultTestLoader，当然你把if __name__ == '__main__'下面的代码换成unittest.main()肯定不成功，除非你把上文提到的testMethodPrefix 换成"Mytest"。有了对TestCase的看法，我们具体来看看这个类。
这个类里面包含了我们所能用的方法。我列出来一些主要的吧。
setUp（）在每个test执行前都要执行的方法。
tearDown()在每个test执行后都要执行的方法。（不管是否执行成功）
setUpClass()在一个测试类中在所有test开始之前， 执行一次 且必须使用到Testsuite(只有在TestSuite的run方法里面才对其调用)
tearDownClass()在一个测试类中在所有test结束之后， 执行一次 且必须使用到Testsuite(只有在TestSuite的run方法里面才对其调用)
run()这是unnitest的核心，逻辑也相对复杂，但是很好理解，具体自己看源码。所有最终case的执行都会归结到该run方法。
还有一个重要的_resultForDoCleanups私有变量，存储TestResult的执行结果，这个在构建后面的skip用到。
我们要明确TestCase类中所有的测试用例是 独立 的，我上面说过了，其实每个testcase就是一个个TestCase类的实例对象，所以不要企图在某个test存储或改变一个变量，下个test中能用到，除非利用到setUpClass。我们看个例子：
import unittest
class Mydemo(unittest.TestCase):
def test1(self):
self.a=1
print "i am test1 the value of a is {}".format(self.a)
def test2(self):
print "i am test2 the value of a is {}".format(self.a)
if __name__ == '__main__':
unittest.main()
结果：
C:\Python27\python.exe D:/Moudle/module_1/test4.py
i am test1 the value of a is 1
.E
======================================================================
ERROR: test2 (__main__.Mydemo)
----------------------------------------------------------------------
Traceback (most recent call last):
File "D:/Moudle/module_1/test4.py", line 7, in test2
print "i am test2 the value of a is {}".format(self.a)
AttributeError: 'Mydemo' object has no attribute 'a' ----------------------------------------------------------------------
Ran 2 tests in 0.001s FAILED (errors=1)
上面就是说明TestCase类中所有的测试用例是独立的，每个testcase就是由TestCase实例化的一个独立的实例。那是不是就是每个TestCase不能共享数据呢？答案是否定的，不能共享的原因是我们上面用到的是self（实例对象属性），能共享我们就必须使用类属性，比如下个例子：
import unittest
class Mydemo(unittest.TestCase):
def test1(self):
Mydemo.a=1
print "i am test1 the value of a is {}".format(self.a)
def test2(self):
print "i am test2 the value of a is {}".format(Mydemo.a)
if __name__ == '__main__':
unittest.main()
运行结果如下：
i am test1 the value of a is 1
..
i am test2 the value of a is 1
----------------------------------------------------------------------
Ran 2 tests in 0.000s OK
这些东西其实是python类的一些动态行为，但是既然和unnitest关联，就随便提下。我们运行test1的时候，给Mydemo加了一个新的属性a（值为1），当我们运行test2时，我们就能拿到Mydemo类的属性了。说了TaseCase我们不得不说下TestSuite。TestSuite是有一个个TestCase组成的，当然TestSuite里面可以再嵌套TestSuite。我们打开C:\Python27\Lib\unittest\suite.py找到TestSuite，它继承于BaseTestSuite，其实主要的一些属性就那么几个：
1.self._tests这个私有变量里面方的是所有的TestCase或者TestSuite。
2.run()方法，方法如下：
def run(self, result, debug=False):
topLevel = False
if getattr(result, '_testRunEntered', False) is False:
result._testRunEntered = topLevel = True for test in self:#这个循环会一直遍历_tests中的变量
if result.shouldStop:
break
if _isnotsuite(test):
self._tearDownPreviousClass(test, result)
self._handleModuleFixture(test, result)
self._handleClassSetUp(test, result)#这一句提到了调用setUpClass的规则
result._previousTestClass = test.__class__ if (getattr(test.__class__, '_classSetupFailed', False) or
getattr(result, '_moduleSetUpFailed', False)):
continue if not debug:
test(result)#如果是TestSuit继续调用该方法，如果是TestCase则调用TestCase中的run方法
else:
test.debug() if topLevel:
self._tearDownPreviousClass(None, result)
self._handleModuleTearDown(result)
result._testRunEntered = False
return result
注释1 ：self是个迭代对象，一直遍历上文提到的self._tests变量
注释2 ：我们看看_handleClassSetUp中的方法，发现在在用例的执行过程中，每个TestCase类只会调用一次setUpClass方法，同理tearDownClass。对用这一点我们举个例子：
import unittest
class Mydemo(unittest.TestCase):
@classmethod
def setUpClass(cls):
print "I am setUpClass"
def test1(self):
print "i am test1 "
def test2(self):
print "i am test2"
@classmethod
def tearDownClass(cls):
print "I am tearDownClass"
if __name__ == '__main__':
unittest.main()
运行结果是：
C:\Python27\python.exe D:/Moudle/module_1/test4.py
I am setUpClass
..
i am test1
----------------------------------------------------------------------
i am test2
Ran 2 tests in 0.001s
I am tearDownClass OK
说明 类方法 setUpClass与tearDownClass只执行了一遍了，这就回答了我们第一个问题了：在setUpClass中启动浏览器，执行完所有流程后关闭浏览器，举一个简单的demo就是：
#coding=utf-8
import unittest
from selenium import webdriver
class Mydemo(unittest.TestCase):
@classmethod
def setUpClass(cls):
cls.browser=webdriver.Firefox()
def test1(self):
'''登录'''
browser=self.browser
#do someting about login
def test2(self):
'''查询'''
browser = self.browser
# do someting about search
def test3(self):
'''提交数据'''
browser = self.browser
# do someting about submmit
@classmethod
def tearDownClass(cls):
browser=self.browser
browser.close()
if __name__ == '__main__':
unittest.main()
上面就会在所有的case执行之前启动firefox,因为每个test中拿到的都是Mydemo类中同一个webdriver对象，所以能保证操作的都是同一个浏览器句柄。关于这个setUpClass如果想要动态的改变某个值一定要使用python的可变的对象比如list,dict等...这些其实都是一些python类的一些知识,算我啰嗦吧我还是想举个例子，嫌烦的同学，绕过这一部分吧。
#coding=utf-8
import unittest
from selenium import webdriver
class Mydemo(unittest.TestCase):
@classmethod
def setUpClass(cls):
cls.a=1
def test1(self):
print "before update the a in test1 is:{}".format(self.a)
self.a=self.a+1
print "after update the a in test1 is:{}".format(self.a)
def test2(self):
print "the value in test2 is:{}".format(self.a)
@classmethod
def tearDownClass(cls):
print "I am tearDownClass"
if __name__ == '__main__':
unittest.main()
运行结果：
C:\Python27\python.exe D:/Moudle/module_1/test4.py
before update the a in test1 is:1
..
after update the a in test1 is:2
----------------------------------------------------------------------
the value in test2 is:1
I am tearDownClass
Ran 2 tests in 0.001s OK
我们想在test1中改变a的值，但是test2中的结果说明a没有被改变，这其实也很好理解。如果我们想要改变怎么办，看看下面的例子：
#coding=utf-8
import unittest
from selenium import webdriver
class Mydemo(unittest.TestCase):
@classmethod
def setUpClass(cls):
cls.a=[0]
def test1(self):
print "before update the a in test1 is:{}".format(self.a[0])
self.a[0]=self.a[0]+1
print "after update the a in test1 is:{}".format(self.a[0])
def test2(self):
print "the value in test2 is:{}".format(self.a[0])
@classmethod
def tearDownClass(cls):
print "I am tearDownClass"
if __name__ == '__main__':
unittest.main()
运行结果：
C:\Python27\python.exe D:/Moudle/module_1/test4.py
..
before update the a in test1 is:0
----------------------------------------------------------------------
after update the a in test1 is:1
Ran 2 tests in 0.000s
the value in test2 is:1 I am tearDownClass
OK
我们把a变成一个list，发现a的值在test2中改变了。好了这一部分就这样了。
注释三 ：这个其实也是python类的一些知识可能有的人没有关注就是__call__这个魔法属性，我们看到在这个循环中test如果是testsuite对象，那么会调用中TestSuite类中的__call__方法（在其父类BaseTestSuite中），该方法中会再次调用run方法。一直到test是个testcase对象，那么就会调用我们上文提到的TestCase中的__call__（这就是我们上面提到为什么找有__call__属性类实例的方法），一样该__call__中的方法也是调用TestCase中的run。所以最终所有的执行其实都是执行TestCase中的run方法。
上面大致讲了一些TestCase与TestSuit的知识，可能穿插的比较多。
如何创建这些Testcase或者TestSuite？
1.自己手动实例化TestCase
这个上面已经有例子，与普通类无异，这中在自动化领域用处不大，我们不能一个个的实例化吧...
2.利用C:\Python27\Lib\unittest\loader.py模块的TestLoader，该类提供了多种不同情境find testcase。
1.loadTestsFromTestCase利用给出的TestCase类名称返回找到所有的suite。
2.loadTestsFromMoudle利用给出的Moudle返回找到所有的suite。
3.loadTestsFromName利用给出的Moudle名称返回找到所有的suite。
4.discover返回给定目录下符合pattern类型(默认test*.py)所有的suite。
其实这些方法最终都要归结到loadTestsFromTestCase，可能官方不提供我们也能写，既然有了就直接用吧。
经过上面的说明，我觉得大家对一TestCase，TestSuite应该有一个比较清楚的认识了，也解决了我自己的提问。问题一：我们可以用类方法setUpClass实现。对于问题二：我们可以利用TestLoader类中的方法返回suite，然后对这些suite按照自己的想法进行一些排序，然后再调用run方法。说完了TestCase我们再说下TestResult。
什么是TestResult？
顾名思义，testresult就是存储测试结果的，不过通过何种方式调用run函数，最终到Testcase中的run方法时必须传一个result（如果为None则自己实例化一个TestResult对象)。这个result就是TestResult对象或者是其子类的对象，我们每次执行的结果都会调用其addFailure，addSuccess，addSkip....等方法将执行结果保存到TestResult实例属性中。我们还是来看看TestCase的run方法：
def run(self, result=None):
orig_result = result
if result is None:#如果没有传入result对象自己实例化一个TestResult对象
result = self.defaultTestResult()
startTestRun = getattr(result, 'startTestRun', None)
if startTestRun is not None:
startTestRun() self._resultForDoCleanups = result
result.startTest(self) testMethod = getattr(self, self._testMethodName)
if (getattr(self.__class__, "__unittest_skip__", False) or
getattr(testMethod, "__unittest_skip__", False)):
# If the class or method was skipped.
try:
skip_why = (getattr(self.__class__, '__unittest_skip_why__', '')
or getattr(testMethod, '__unittest_skip_why__', ''))
self._addSkip(result, skip_why)#调用addSkip
finally:
result.stopTest(self)
return
try:
success = False
try:
self.setUp()
except SkipTest as e:
self._addSkip(result, str(e))
except KeyboardInterrupt:
raise
except:
result.addError(self, sys.exc_info())#调用addError
else:
try:
testMethod()
except KeyboardInterrupt:
raise
except self.failureException:
result.addFailure(self, sys.exc_info())#调用addFailure
except _ExpectedFailure as e:
addExpectedFailure = getattr(result, 'addExpectedFailure', None)
if addExpectedFailure is not None:
addExpectedFailure(self, e.exc_info)#调用addExpectedFailure
else:
warnings.warn("TestResult has no addExpectedFailure method, reporting as passes",
RuntimeWarning)
result.addSuccess(self)#调用addSuccess
except _UnexpectedSuccess:
addUnexpectedSuccess = getattr(result, 'addUnexpectedSuccess', None)
if addUnexpectedSuccess is not None:
addUnexpectedSuccess(self)
else:
warnings.warn("TestResult has no addUnexpectedSuccess method, reporting as failures",
RuntimeWarning)
result.addFailure(self, sys.exc_info())
except SkipTest as e:
self._addSkip(result, str(e))
except:
result.addError(self, sys.exc_info())
else:
success = True try:
self.tearDown()
except KeyboardInterrupt:
raise
except:
result.addError(self, sys.exc_info())
success = False cleanUpSuccess = self.doCleanups()
success = success and cleanUpSuccess
if success:
result.addSuccess(self)
finally:
result.stopTest(self)
if orig_result is None:
stopTestRun = getattr(result, 'stopTestRun', None)
if stopTestRun is not None:
stopTestRun()
通过注释部分我们可以看出，每次执行用例时，都会把执行结果保存到TestResult中。我们再看看TextTestRunner这个类，在开始就使用了类TextTestResult，而这个类也是继承TestResult，而后在执行的过程中最终把TextTestResult实例对象传递给TestCase的run方法。所以我上文说了，不过你是用什么方式执行unnitest,到最后都是TestCase的run方法与TestResult的游戏。 而我们的HTMLTestRunner模块也是在继承在TestResult类的基础上的。
说完了TestCase我们来看看第三个问题吧，也是比较有实际意义的话题，开始我是这样跳过某些test的，代码是这样的：
#coding=utf-8
import unittest
a=[False]
class Mydemo(unittest.TestCase):
def test1(self):
try:
print "i am test1"
#test 1 do some thing
except Exception,e:
a[0] = True
raise e
@unittest.skipIf(a[0],"test1 fail skip test2")
def test2(self):
try:
print "i am test2"
raise AssertionError("error")
# test2 do some thing
except Exception,e:
a[0] = True
raise e
@unittest.skipIf(a[0], "test1 fail skip test2")
def test3(self):
try:
print "i am test3"
# test2 do some thing
except Exception, e:
a[0] =True
raise e
if __name__ == '__main__':
unittest.main()
想法很简单：就是利用一个全局的数组，如果某个test执行出错我就更改这个数组元素，到下一个case执行的时候就会判断是否要跳过。上面因为test2出错了，原本我们想跳过test3，但是很遗憾并没有跳过test3！结果如下：
C:\Python27\python.exe D:/Moudle/module_1/test4.py
i am test1
.F.
i am test2
======================================================================
i am test3
FAIL: test2 (__main__.Mydemo)
----------------------------------------------------------------------
Traceback (most recent call last):
File "D:/Moudle/module_1/test4.py", line 20, in test2
raise e
AssertionError: error ----------------------------------------------------------------------
Ran 3 tests in 0.000s FAILED (failures=1)
原因很简单：python在创建Mydemo这个类的时候，由于实例方法都使用了装饰器unittest.skipIf，所以每个方法都向unittest.skipIf这个装饰传递传递参数a[0]，但是这个a[0]是没用执行过任何case之前的a[0],也就是我们刚开始定义的a[0]=Flase，所以不可能跳过的。退一万步讲，即使这样可行，也太不美观了吧。我们想的是当执行当前的test时能判断前面是否有出错的case，有的话就跳过了。可行吗?我觉得可行。主要就是用到我上面提到的TestCase中的_resultForDoCleanups的变量，这个其实就是TestResult一个引用。那么我们可以这样写：
#coding=utf-8
import unittest
class Mydemo(unittest.TestCase):
def test1(self):
print "excute test1"
def test2(self):
if self._resultForDoCleanups.failures or self._resultForDoCleanups.errors:
raise unittest.SkipTest("{} do not excute because {} is failed".format(self._testMethodName,self._resultForDoCleanups.failures[0][0]._testMethodName))
print "excute test2"
raise AssertionError("test2 fail") def test3(self):
if self._resultForDoCleanups.failures or self._resultForDoCleanups.errors:
raise unittest.SkipTest("{} do not excute because {} is failed".format(self._testMethodName,self._resultForDoCleanups.failures[0][0]._testMethodName))
print "excute test3"
if __name__ == '__main__':
unittest.main()
运行结果如下：
.Fs
======================================================================
FAIL: test2 (__main__.Mydemo)
----------------------------------------------------------------------
Traceback (most recent call last):
File "D:/Moudle/module_1/test4.py", line 10, in test2
raise AssertionError("test2 fail")
AssertionError: test2 fail ----------------------------------------------------------------------
Ran 3 tests in 0.001s FAILED (failures=1, skipped=1)
excute test1
excute test2
可以了，我们看出，test2失败了，test3跳过;当然test2如果正确，test3会执行。目的是达到了，可是每个case都这样写不太好，我们想到了装饰器(不会自行百度)，在C:\Python27\Lib\unittest\case.py中新增如下代码：
def Myskip(func):
def RebackTest(self):
if self._resultForDoCleanups.failures or self._resultForDoCleanups.errors:
raise unittest.SkipTest("{} do not excute because {} is failed".format(func.__name__,self._resultForDoCleanups.failures[0][0]._testMethodName))
func(self)
return RebackTest
然后C:\Python27\Lib\unittest\__init__.py中新增：
__all__ = ['TestResult', 'TestCase', 'TestSuite',
'TextTestRunner', 'TestLoader', 'FunctionTestCase', 'main',
'defaultTestLoader', 'SkipTest', 'skip', 'skipIf', 'skipUnless',
'expectedFailure', 'TextTestResult', 'installHandler',
'registerResult', 'removeResult', 'removeHandler','Myskip']
......
from .case import (TestCase, FunctionTestCase, SkipTest, skip, skipIf,Myskip,
skipUnless, expectedFailure)
最终我们这样写：
#coding=utf-8
import unittest
class Mydemo(unittest.TestCase):
def test1(self):
print "excute test1"
@unittest.Myskip
def test2(self):
print "excute test2"
raise AssertionError("test2 fail")
@unittest.Myskip
def test3(self):
print "excute test3"
if __name__ == '__main__':
unittest.main()
好了，看上去还不错....关于其他的unnitest相关知识，不想再扯了，最后拓展HTMLTestRunner报告，这可能是大家关心的！写这个HTMLTestRunner的大神是在好久之前的了,基本能满足大家需求。但是，目前对于web自动化，我觉得至少要新增2个东西。第一个新增skip列：因为我可能会skip某些case；第二新增截图列,如果有错误我可能要截图。
打了这么久字不想再多说了....我给出全部代码，然后代码中我改变的地方我给出标记并加注释吧，完整代码如下：(可能有点长，但是要有点耐心)

把上面代码复制覆盖原来的HTMLTestRunner就好，截图那块我是把错误的图像放在apache服务器的某个路径下的，如果有错误就显示图片超链接，没有就隐藏这超链接。
关于上面的改动其实很简单，熟悉一定的前端语言(html.javascript)即可。HTMLTestRunner原理就是我们上文提到的利用_TestResult继承unnitest中的TestResult类，并重写了addSuccess，addSkip，addError等方法，把测试结果放在一个self.result里面，最后遍历这个result利用前端的一些知识生成一个html报告。这边贴图贴一下生成的样式吧，执行testcase的代码：
#coding=utf-8
import unittest
import HTMLTestRunner
import sys,os
class Mydemo(unittest.TestCase):
def test1(self):
print "excute test1"
@unittest.Myskip
def test2(self):
print "excute test2"
raise AssertionError("test2 fail")
@unittest.Myskip
def test3(self):
print "excute test3"
@unittest.Myskip
def test4(self):
print "excute test4"
if __name__ == '__main__':
module_name=os.path.basename(sys.argv[0]).split(".")[0]
module=__import__(module_name)
fp=file("./new.html","wb")
runner=HTMLTestRunner.HTMLTestRunner(fp)
all_suite=unittest.defaultTestLoader.loadTestsFromModule(module)
runner.run(all_suite)
最后生成的报告如下：
说了这么多只是希望大家能对unnitest有更多的了解，当然如果你已经懂的更多或者认为我某些地方说错了，请一笑而过....
