Robolectric 2.1 and Eclipse

问题

Robolectric seems to be a very interessting alternative android application testing, but I can't properly integrate it with my Eclipse enviroment.

Using the latest robolectric version 2.1 and android sdk 8, I follow the Eclipse setup steps described on the robolectric website but with no luck. When I run my newly created run configuration, the test is stopped the following error.

I don't know exactly why my pakpak .R class cant be found and what is the ro.build.date.utc? a symptom or the problem?

WARNING: no system properties value for ro.build.date.utc

I kinda solved my issue, where I can at least run my tests to a point which makes some sense to me. In Robolectric 2.0 they allow you to specify the path to your AndroidManifest file by creating a Config.properties file in your test project.

Try these two steps and see if they work for you:

Create a nodescript file (File > New > File) called 'org.robolectric.Config.properties' at your test's src directory.
In the org.robolectric.Config.properties file add the line

manifest:[relative path your AndroidManifest.xml]

I had to mess with the relative path a bit (kept adding/removing ../'s), but this got it to correctly find my AndroidManifest file.

You can find more info at this github issue or their configuring robolectric blog post. Both of which I found to not be straight forward enough.
