PTVS：单元测试源路径

Question

Using Python Tools for Visual Studio, I created a 'project from exisiting source'. I can run it's main application file, but every unit test (automatically discovered!) fails to start:

ImportError: No Module named src.xyz.unit.TestThisAndThat

My python sources are in a folder called 'src', which isn't a package. In this case, I'm looking for a way to configure the 'source' path.

Summarizing:

How can I configure the source path to use for running unit tests?

Answer 1

一种选择（尽管不是那么可扩展）是将项目的路径-'... path_to / src'添加到系统变量PYTHONPATH并重新启动ptvs。
