Using objenesis prevents running tests from interactive prompt more than once #306

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem? If possible, provide source code and 
stack trace.

If I include the objenesis dependency in my BuildConfig, my tests run fine when 
executed as 'grails test-app' but fail after the first run if I go into 
interactive mode by typing 'grails' and then issuing 'test-app' calls. This has 
happened in two distinct apps.

The stacktrace is here (I cannot get Grails to give me the entire stacktrace 
either using -Dgrails.full.stacktrace=true or specifying grails.full.stacktrace 
= true in Config.groovy):

I have the same issue but it is not linked to interactive mode.
It's happening when I have one unit spock test that mock a specific service and 
another unit spock integration test that mock the same service.

If I run them together for being tested, it's not working. If I test them 
separatly, it's working.

I am not in the Grails environment, but I am having the same issue.  Tests with 
mocked resources pass in isolation but, when run as a testing suite, fail with 
the exception: 

org.spockframework.mock.CannotCreateMockException: Cannot create mock for class 
[myClass]null

Is there a specific Mock teardown that needs to be performed to free up those 
resources and allow future mock instances to be created?

I am seeing this with Spock 0.7, Groovy 1.8

According to mrmattrichards, he is experiencing this problem outside Grails (or 
does he just mean outside Grails interactive mode?). It would be very helpful 
if I could reproduce this. If the problem only occurs in Grails (and this is my 
current understanding), we will have to find a person knowledgable in Grails 
internals to look into this.

I'm also experiencing this problem in a grails 2.3.0 app where we use mocks in 
unit tests and also in integration tests.

When ran with jUnit, tests pass. This problem only occurs when running tests 
with grails.

The bug doesn't occur when useObjenesis: false

Having the same issue here when running both unit and integration grails tests 
and using mocks in both type of tests with objenesis on the classpath. I can 
confirm that using Mock(useObjenesis: false) when the mocking fails in 
integration tests is a valid workaround.

See Issue 335. Recent Grails versions implement a workaround. Plan to fix for 
1.0.
