[开发测试]unittest、Fixture、parameterized、断言、测试报告

1.unittest

例1：

mymytest.py 和main.py都在case文件夹中

在mymytest.py文件中

import unittest
def two_he(a,b):
    print(a+b)
    return a+b

class BdTestClass(unittest.TestCase):
    def test_1(self):
        two_he(1,2)

在main.py文件中

import unittest
from case import mymytest

suite=unittest.TestSuite()
suite.addTest(mymytest.BdTestClass("test_1"))
runner=unittest.TextTestRunner()
runner.run(suite)

例2：

mymytest.py 和main.py都在case文件夹中

在mymytest.py文件中

import unittest

# 待测函数
def two_he(a,b):
    print(a+b)
    return a+b

# 测试类：方法-->测试用例
# 注意事项：测试类，必须继承unittest.TestCase
# 测试用例：就是方法，方法必须以test开头

class BdTestClass(unittest.TestCase):
    def test_1(self):
        two_he(1,2)

    def test_2(self):
        two_he('abc',5)

在main.py文件中

import unittest
from case import mymytest

suite=unittest.TestSuite()
suite.addTest(mymytest.BdTestClass("test_1"))
suite.addTest(mymytest.BdTestClass("test_2"))
runner=unittest.TextTestRunner()
runner.run(suite)

例3：

mymytest.py 和main.py都在case文件夹中

在mymytest.py文件中

import unittest
def two_he(a,b):
    print(a+b)
    return a+b

class BdTestClass(unittest.TestCase):
    def test_1(self):
        two_he(1,2)

    def test_2(self):
        two_he('abc',5)

在main.py文件中

import unittest
from case import mymytest

suite=unittest.TestSuite()
suite.addTest(unittest.makeSuite(mymytest.BdTestClass))
runner=unittest.TextTestRunner()
runner.run(suite)

和例2效果一样

例4：

测试一个文件夹下的所有要测的文件

mymytest.py 和yotest.py都在case文件夹中

main.py文件在case文件夹之外（和cace同级）

在mymytest.py文件中

import unittest
def two_he(a,b):
    print(a+b)
    return a+b

class BdTestClass(unittest.TestCase):
    def test_1(self):
        two_he(1,2)

    def test_2(self):
        two_he('abc',5)

在yotest.py文件中

import unittest
def th_he(a,b,c):
    print(a+b)
    return a+b

class ShTestClass(unittest.TestCase):
    def test_1(self):
        th_he(1,2,3)

    def test_2(self):
        th_he('abc',5,6)

在main.py文件中

import unittest

suite=unittest.TestLoader().discover('../case','*test.py')
runner=unittest.TextTestRunner()
runner.run(suite)

yotest.py和mymytest.py文件都测试

        content=f.read()
        d=[(i["x"],i["y"],i["exp"]) for i in json.loads(content)]
        return d

class BdTestClass(unittest.TestCase):

    @parameterized.expand(build_data)  # build_data() 也可以

import unittest
from case import mymytest

suite=unittest.TestSuite()
suite.addTest(unittest.makeSuite(mymytest.BdTestClass))

4.生成HTML测试报告

?建一个py文件，与case文件夹同级，名字是HTMLTestRunner.py，把下面的代码粘贴进去

"""
A 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.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.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)
