How does one test a method that does some interactions with the local D-Bus (accessing a HAL object)?
如何测试与本地D-Bus进行某些交互(访问HAL对象)的方法?
Results of tests will differ depending on the system that the test is run on, so I don't know how to provide the method reliable input.
测试结果将根据运行测试的系统而有所不同,因此我不知道如何提供方法可靠的输入。
I'm working in Python, by the way.
顺便说一下,我正在使用Python。

If you can not mock the environment then it's probably impossible for you to write the test. If your access to HAL/D-Bus is via an object and you provide a mock instance to your test then it should be possible to emulate the necessary inputs to your test from the mock implementation.
如果你不能模仿环境,那么你可能无法编写测试。如果您通过对象访问HAL / D-Bus并且您为测试提供了一个模拟实例,那么应该可以从模拟实现模拟测试的必要输入。

It's also possible to create a temporary D-Bus buses for tests, and emulate any services your program uses in your test code. You can use this approach for programs which are D-Bus services, D-Bus clients, or both. The downside is that the bus setup is a bit hairy. There's code for doing this in e.g. Telepathy Gabble.
也可以为测试创建临时D-Bus总线,并模拟程序在测试代码中使用的任何服务。您可以将此方法用于D-Bus服务,D-Bus客户端或两者的程序。缺点是总线设置有点毛茸茸。有这样的代码,例如:心灵感应加布尔。
