[英]Python unit-testing in multiple threads
I would like to unit-test the functionality of a few classes that mainly do file in- and output. 我想对一些主要用于文件输入和输出的类的功能进行单元测试。 Furthermore I would like to do that on multiple cores (--jobs=4).
此外,我想在多个内核上执行此操作(--jobs = 4)。
The problem is, that the files that are created by the classes often have the same name and they get mixed up in multiple threads. 问题是,由类创建的文件通常具有相同的名称,并且在多个线程中混杂在一起。 What I do currently is that I run each unit-test in a separate directory like so:
我目前要做的是,在这样的单独目录中运行每个单元测试:
def test(self):
if os.path.exists("UniqueDir"):
os.system("rm -rf UniqueDir")
os.mkdir("UniqueDir")
os.chdir("UniqueDir")
#Do the actual testing
os.chdir("..")
os.rmdir("UniqueDir")
The downsides are very obvious: 缺点非常明显:
What approach could I use to 1. separate my tests from one another but 2. do it in a more elegant way? 我可以使用哪种方法1.将测试彼此分开,但是2.以一种更优雅的方式进行?
Any help, suggestion etc. is appreciated! 任何帮助,建议等,不胜感激!

I would suggest to use the unittest module and build the classes like this: 我建议使用unittest模块并构建如下的类:
import unittest
from tempfile import mkdtemp
class Test(unittest.TestCase):
def setUp(self):
self.tempdir = mkdtemp()
os.chdir(self.tempdir)
def tearDown(self):
os.rmdir(self.tempdir)
def testName(self):
#Do the actual testing
pass
if __name__ == "__main__":
unittest.main()
Additionally you could add multiprocessing to create 4 threads. 另外,您可以添加多处理以创建4个线程。
Edit: removed the os.mkdir because mkdtemp creates a temp directory so it's bogus. 编辑:删除了os.mkdir,因为mkdtemp创建了一个临时目录,所以它是虚假的。 Thx Sebastian.
