Unittest 多程序 裝飾器 額外傳參給測試類

呼叫unittest.main()時無法傳入額外的引數給我們的測試類時，可以使用如下工具給我們的測試類新增額外的引數：

unittest_utils.py**：

import unittest

class parametrizedtestcase(unittest.testcase):
""" testcase classes that want to be parametrized should
inherit from this class.
"""def __init__(self, method_name='runtest', param=none):
super(parametrizedtestcase, self).__init__(method_name)
self.param = param
@staticmethod
def parametrize(test_case_class, param=none):
""" create a suite containing all tests taken from the given
subclass, passing them the parameter 'param'.
"""test_loader = unittest.testloader()
test_names = test_loader.gettestcasenames(test_case_class)
suite = unittest.testsuite()
for name in test_names:
suite.addtest(test_case_class(name, param=param))
return suite

（1）需要讓測試類繼承自parametrizedtestcase

（2）新增額外引數

suite = unittest.testsuite()

suite.addtest(parametrizedtestcase.parametrize(testandroid, param=data))
runner = unittest.texttestrunner()
runner.run(suite)

import unittest

from multiprocessing import process
from demo.test_demo import testandroid
from utils.unittest_utils import parametrizedtestcase
class myprocess(process):
def __init__(self, data):
process.__init__(self)
self.data = data
self.suite = none
def run(self):
parametrizedtestcase.data = self.data
self.suite = unittest.testsuite()
# 此處param即為給測試類額外傳入的引數
self.suite.addtest(parametrizedtestcase.parametrize(testandroid, param=self.data))
runner = unittest.texttestrunner()
runner.run(self.suite)
def create_process_monkey(data):
process_instances = 
for d in data:
instance = myprocess(d)
for instance in process_instances:
instance.start()
if __name__ == "__main__":
process01 = 
process02 = 
create_process_monkey([process01, process02])

def add_log(func):

# 獲取用例名稱
case = func.__name__
print(case + " : start ...")
print("")
# 執行測試用例
func(*args)
print(case + " : end ...")
print("")

import os

from utils.logger import add_log
from utils.unittest_utils import parametrizedtestcase
class testandroid(parametrizedtestcase):
def setup(self):
pass
# 格式化輸出裝飾器
@add_log
def test_calculate(self):
print("當前程序的pid是： " + str(os.getpid()))
self.asserttrue(eval(self.param["calculate"]) == int(self.param["value"]))
def teardown(self):
pass
