相比pytest自帶的許多插件可以實(shí)現(xiàn)漂亮的測(cè)試報(bào)告歹撒，以及自帶的功能pytest.mark.parametrize可以用于數(shù)據(jù)驅(qū)動(dòng)
另一個(gè)測(cè)試框架unittest就沒(méi)有那么方便了妹孙，其沒(méi)有自帶的數(shù)據(jù)驅(qū)動(dòng)功能也沒(méi)有自帶的漂亮報(bào)告
所以我們引用了兩個(gè)第三方庫(kù)

• ddt
• HTMLTestRunnerNew

tips: 此HTMLTestRunnerNew基于https://pypi.org/project/HTMLTestRunner/做了修改倦炒，這個(gè)也是我在網(wǎng)上找的優(yōu)化版，因?yàn)樘噢D(zhuǎn)載的具體是誰(shuí)優(yōu)化的實(shí)在找不到源頭刁卜。若知道該源碼是誰(shuí)做了修改麻煩留言我即刻改正
原作者博客：http://tungwaiyip.info/software/HTMLTestRunner.html

數(shù)據(jù)驅(qū)動(dòng)的優(yōu)缺點(diǎn)

• 優(yōu)點(diǎn)：
  • 提高代碼復(fù)用率
  • 代碼結(jié)構(gòu)清晰
  • 易于維護(hù)
• 缺點(diǎn)：
  • 使用場(chǎng)景較少

ddt使用

這邊只講常用的三個(gè)函數(shù)：

• ddt：
  • 裝飾在類(lèi)上面且只能用于裝飾unittest.TestCase的子類(lèi)
  • 用于修改unittest框架的用例讀取
• data(*vlaue)：
  • 裝飾在需要使用的用例函數(shù)上志电，且該類(lèi)一定要裝飾了ddt
  • 用于讀取數(shù)據(jù)并賦值給用例
  • value：該處如果傳tuple、list需要進(jìn)行unpack
• file_data(value)
  • value應(yīng)該是相對(duì)于包含修飾的unittest.TestCase的文件目錄的相對(duì)路徑长酗。該文件應(yīng)包含JSON編碼的數(shù)據(jù)溪北，可以是列表或字典
  • json文件的具體展現(xiàn)形式，不做解讀 大家自己研究適合自己的格式

tips: 實(shí)現(xiàn)ddt的unittest用例名參數(shù)化

在使用ddt進(jìn)行數(shù)據(jù)驅(qū)動(dòng)時(shí)夺脾，測(cè)試用例的名字呈現(xiàn)的是： 用例函數(shù)1 用例函數(shù)2 用例函數(shù)3 ……testcase + index 在報(bào)告和運(yùn)行中完全無(wú)法識(shí)別是什么用例
所以我們要對(duì)ddt源碼進(jìn)行一點(diǎn)小小的修改之拨。 位置是ddt庫(kù)源碼的ddt函數(shù)(284行)
源碼中 _test_data_docstring 方法其實(shí)就是個(gè)生成用例名字的函數(shù)，但因?yàn)樗枰氖莀doc_所以在數(shù)據(jù)驅(qū)動(dòng)中很難實(shí)現(xiàn)動(dòng)態(tài)參數(shù)化變化

def _get_test_data_docstring(func, value):
    """Returns a docstring based on the following resolution strategy:
    1. Passed value is not a "primitive" and has a docstring, then use it.
    2. In all other cases return None, i.e the test name is used.
    """
    if not _is_primitive(value) and value.__doc__:
        return value.__doc__
    else:
        return None

查看源碼可以看出 i,v 分別是 索引下標(biāo)和對(duì)應(yīng)參數(shù)咧叭。因?yàn)槲覕?shù)據(jù)驅(qū)動(dòng)傳入的用例參數(shù)為實(shí)例化對(duì)象object所以采用的是對(duì)象屬性的方式
object.attr （我用例中title為用例名所以在下方源碼中為 v.title)
有些朋友可能傳的是字典等蚀乔，此處就可修改成 v[key] key為數(shù)據(jù)源中設(shè)置的用例名

def ddt(cls):
    """
    Class decorator for subclasses of ``unittest.TestCase``.

    Apply this decorator to the test case class, and then
    decorate test methods with ``@data``.

    For each method decorated with ``@data``, this will effectively create as
    many methods as data items are passed as parameters to ``@data``.

    The names of the test methods follow the pattern
    ``original_test_name_{ordinal}_{data}``. ``ordinal`` is the position of the
    data argument, starting with 1.

    For data we use a string representation of the data value converted into a
    valid python identifier.  If ``data.__name__`` exists, we use that instead.

    For each method decorated with ``@file_data('test_data.json')``, the
    decorator will try to load the test_data.json file located relative
    to the python file containing the method that is decorated. It will,
    for each ``test_name`` key create as many methods in the list of values
    from the ``data`` key.

ddt使用實(shí)例：

a = (1, 2, 3, 4)
b = [1, 2, 3, 4]
c = [(1, 2), (3, 4), (5, 6)]
@ddt
class RegisterTestCase(unittest.TestCase):

   @data(a)  # 此時(shí)未對(duì)數(shù)據(jù)進(jìn)行unpack吉挣，則只有一個(gè)用例，a變量將當(dāng)作一個(gè)參數(shù)傳入用例
   def test_register(self, case):  # case為@data傳入?yún)?shù)的變量名婉弹，任意名字睬魂，函數(shù)除self變量外的第一個(gè)
         print(case)

   @data(*a)  # 等同于@data(*b) unpack后 相當(dāng)于@data(1, 2, 3, 4) 會(huì)有4個(gè)數(shù)據(jù)遍歷的形式傳入用例，將有4條用例
   def test_register(self, case):
         print(case)  # 1 2 3 4
   @data(*c)  # 此時(shí)相當(dāng)于@data((1, 2), (3, 4), (5, 6)) 每次傳入一個(gè)元組
   def test_register(self, case):
         print(case)  # (1, 2) (3, 4) (5, 6)

HTMLTestRunner使用：

使用HTMLTestRunner前镀赌，需要使用unittest.TestSuite().addTest等單元測(cè)試添加用例的方法添加相關(guān)用例
因?yàn)镠TMLTestRunner的函數(shù)內(nèi)已有unittest運(yùn)行的方法氯哮，所以無(wú)需再使用unittest.run等單元測(cè)試啟動(dòng)方法
unittest的使用傳送門(mén)

    suite = unittest.TestSuite()
    loader = unittest.TestLoader()
    suite.addTest(loader.loadTestsFromTestCase(SmokeTest))  # 添加用例
    with open(path, 'wb') as f:  # 使用上下文，path為報(bào)告輸入地址
        runner = HTMLTestRunner(self, stream=f, verbosity=2,title="DEMO",description="這個(gè)是個(gè)demo", tester="測(cè)試人員")
        # HTMLTestRunner(self, stream=sys.stdout, verbosity=2,title=None,description=None,tester=None)
        # stream 上下文對(duì)象
        # verbosity 報(bào)告的詳細(xì)程度 2為最詳細(xì) 0為最簡(jiǎn)潔
        # title 報(bào)告標(biāo)題
        # description 描述
        # tester 測(cè)試人員
        runner.run(suite)

HTMLTestRunner

以下是HTMLTestRunnerNew源碼

#coding=utf-8
"""
A連接信息 TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.
The simplest way to use this is to invoke its main method. E列表.g.
    import unittest
    import HTMLTestRunner
    ... define your tests ...
    if __name__ == '__main__':
        HTMLTestRunner.main()
For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest's TextTestRunner. E列表.g.
    # output to a file
    fp = file('my_report.html', 'wb')
    runner = HTMLTestRunner.HTMLTestRunner(
                stream=fp,
                title='My unit test',
                description='This demonstrates the report output by HTMLTestRunner.'
                )
    # Use an external stylesheet.
    # See the Template_mixin class for more customizable options
    runner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'
    # run the test
    runner.run(my_test_suite)
