XML : the unit test for android studio will not start because the styles.xml file cannot find the "Theme.AppCompat.Light.DarkActionBar"

SO to preface this question, I am a complete beginner with Unit testing and I know next to nothing on xml files. But I am trying to test the database using an AndroidJUnit4 test and the test keeps failing. I have tried commenting it out but it still will not work.

this is the error I get.

Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Bennett\AppData\Local\Android\sdk\build-tools\22.0.1\aapt.exe'' finished with non-zero exit value 1

it also says for the "Theme.AppCompat.Light.DarkActionBar" : cannot resolve symbol
