Mockito cannot mock this class #322

Closed jaumard closed 5 years ago

jaumard commented 5 years ago

All was working great before, but now I'm getting this error:

org.mockito.exceptions.base.MockitoException: 
Mockito cannot mock this class: class com.dspread.xpos.QPOSService.

If you're not sure why you're getting this error, please report to the mailing list.

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.

This class is under a Gradle dependency, but does look like it's final or anything. I updated my java version recently maybe it's because of this... How can I fix this ? I'm using Mockito-kotlin 2.1.0

The first failing test give me this, but all the other ones give:

Don't know if it help or not

tadfisher commented 5 years ago

Started seeing this after the Kotlin 1.2.20 update.

jaumard commented 5 years ago

Using Kotlin 1.2.10, 1.2.71 and 1.3.20 and get the same error on my side

bohsen commented 5 years ago

Proguard issues? See this issue

freezy commented 5 years ago

@tadfisher Do you remember which Kotlin version used to work before the upgrade to 1.2.20?

mbarroux commented 5 years ago

FYI kotlin 1.3.30, mockito-kotlin 2.1.0 and mockito-core 2.23.0 => OK but as soon as I upgrade mockito-core to 2.24.0 => KO

bohsen commented 5 years ago

@jaumard @mbarroux Could you post a reproducible example of your tests that fails.

Also, possible causes of java.lang.Verifyerror can be found here.

nhaarman commented 5 years ago

Closing this for lack of a reproducible example. If this is still an issue, please create a new issue with the missing information.
