任何人都可以解释一下可能出现的问题：
我通过buildout安装了一个新的Plone 4.1.4，并创建了一个新的开箱即用的Plone站点（该站点没有工作）。在运行./bin/test --all testsuite（只是出于好奇）后，它会出现以下很多错误：

这不是运行测试的受支持方式。 Plone组件的一些测试会改变全局状态，然后不会自行清理，导致稍后运行的测试失败，这取决于该状态是否是某种特定方式。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，但它是一个实用的解决方案，直到有人完成找到并解决测试隔离问题的工作。
