单元测试框架：在新进程中运行测试

我编写了一个使用Unit testing framework的GUI应用程序。该应用程序在树视图中显示所有找到的单元测试。如果您单击单元测试名称，程序将运行此测试并显示结果。它的工作原理！单元测试框架：在新进程中运行测试

但是现在我希望每个测试用例都运行在一个新的进程中。我创建了一个“工作线程”（带有模块线程），但是此线程也在同一进程中运行。

模块“multiprocessing”是解决方案，但我遇到了问题，我的实施。我把我的“测试执行代码”在自己的功能和尝试：

item = self.GetSelection() 
name = self.GetItemText(item) 
p = multiprocessing.Process(target=ExecuteTest, args=(name, item)) 
p.daemon = True 
p.start()

但后来我得到了错误。

有没有人有什么想法？

显然，你试图“腌制”一些不可取的东西（似乎是一个wx对象）。尝试仅用作参数“简单”对象（即没有图形对象），它应该工作得更好。您也可以看看python nose unitest库，它允许您自动运行多进程中的测试。

使用fork产生子进程。这将需要你的一些工作，但会起作用。

作为说明：multiprocessnig模块是使用fork实现的。

更新：你的代码仔细看后似乎item viariable不与pickle（就是一个字？）。我不认为你需要它，因为你可以用简单的东西（一个值或某种类型）代替它。

“pickleable（这是一个词？）”，那么'pythonic'呢？或'voooooooooooom' – SingleNegationElimination

我建议您创建一个运行测试的单独脚本，然后您可以使用subprocess模块调用该脚本，并为其提供要运行的测试的名称。

好处是，您可以在持续集成服务器，每晚构建或其他不需要GUI的批处理类型进程中使用同一脚本。
