It looks like you are a Mac user. Have you tried your project on the command line?

There is a nice page with excellent information on how to get started with robolectric: http://robolectric.org/getting-started/ and there you will get the following hint.

Note for Mac users

If you are on a Mac, you may have to configure the default JUnit test run configuration to work around the error in which Android Studio does not set the working directory of the module under test. This can be done by editing the launch configurations, Defaults → JUnit and changing the value of the working directory to $ MODULE_DIR $.

Also try adding

 <uses-sdk android:targetSdkVersion="21" /> 

to your AndroidManifest.xml

and

 @RunWith(RobolectricTestRunner.class) @Config(manifest = "src/main/AndroidManifest.xml") 

for your test classes.
