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

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 = ''
# run the test
runner.run(my_test_suite)
