Android - Mockito cannot mock this class: class android.content.Context

[Gurappa Chenchugari]

We had Mockito version 2.18.3. Now I upgraded to 3.5.13.
Also Robolectric version is upgraded from 3.8 to 4.4.

Also gradle version from 3.3.1 to 4.0.0

  You are seeing this disclaimer because Mockito is configured to create inlined mocks. 

You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc. Underlying exception : org.mockito.exceptions.base.MockitoException: Could not modify all classes [class android.content.Context] at net.abc.def.MyTest.onSetUp(FirstTest.java:51)

The root cause lists the following:

Caused by: java.lang.UnsupportedClassVersionError: android/os/Bundle has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Which version of Java are you using? https://github.com/mockito/mockito/issues/2065 might be helpful.

This is what I have in my Android Studio:

java version "1.8.0_162"

Java(TM) SE Runtime Environment (build 1.8.0_162-b12)

Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)

As per https://site.mockito.org/ :
“Mockito 3.x requires Java 8, but otherwise doesn’t introduce any breaking changes compared to the 2.x series.”

so looks like that is not a problem ?

Ah bummer. Please file an issue on our issue tracker with a minimal reproduction case and we can take a look.
