10 years ago I found the explanation of this problem. I tried to mock a class instead of an interface with Easymock.
I've just replaced this line HelperDate mockHelperDate = EasyMock.createMock(HelperDate.class); by HelperDate mockHelperDate = EasyMock.createMock(IHelperDate.class); with IHelperDate an interface implemented by HelperDate.
This issue can be closed.
Hi, I studied the sample android-sample-robolectric-tests. I tried to create an android-demo project with a simple HelloWorld Activity and a button in order to display the current date in a Toast when the button is clicked. I could implemented some tests like your sample but I have a problem with EasyMock. I used the same version of the testing librairies than your sample.
My problem is when I try to mock a class from my Android projet or a simple class like String. For example : HelperDate mockHelperDate = EasyMock.createMock(HelperDate.class); The error is below.
I tried to add the librairy dexmaker v1.0 but I had an other error because no device is connected. If I understand dexmarker is required for test on device. Could you please help to solve my problem ? Best regards, Franck
