Plone test-runner错误

Question

有没有人能解释一下哪里出了问题：

我有一个新的Plone 4.1.4安装通过buildout和一个新的开箱即用的Plone网站创建(没有工作在网站上做)。在运行./bin/test --all testsuite (出于好奇)之后，它给出了许多以下错误：

这不是一种运行测试的受支持方式。Plone组件的一些测试更改了全局状态，然后不会在它们自身之后进行清理，从而导致后来运行的测试失败，这些测试依赖于该状态是以某种方式进行的。我们用来开发Plone的环境buildout.coredev使用plone.recipe.alltests构建配方来设置一个脚本，该脚本可以通过将一些包与其他包隔离来成功运行所有测试。

这当然不是理想的，但这是一个实用的解决方案，直到有人找到并解决测试隔离问题。
