dexopener's Issues
Dexopener not working
after applying this lib to my project i still get the error below
Mockito can only mock non-private & non-final classes.
If you're not sure why you're getting this error, please report to the mailing list.
IMPORTANT INFORMATION FOR ANDROID USERS:
The regular Byte Buddy mock makers cannot generate code on an Android VM!
To resolve this, please use the 'mockito-android' dependency for your application:

Package path
Continueing on #20 and by looking at the implementation I don't see a reason why the user of this library shouldn't be able to define one or more package paths to "open" himself. IMHO the "reasonable default" that the JUnit runner must reside inside the root path and that all modules must have either the same root path or have packages underneath that sounds like an artificial limitation.
Could you elaborate a bit more what made you do this decision?
DexOpener.Builder example in README misled me
Hi,
Thanks for this great library, I can finally mock my Kotlin classes! I tried to follow the instructions for DexOpener.Builder in the README and couldn't get it working until I followed the version in the sample code, which just uses return super.newApplication(cl, className, context).
Maybe update it to just use that?
UI Tests fail on API 23, but not on API 24+
Hello Tsuyoshi,
DexOpener is pretty much the only way we have found to be able to test using Espresso and Mockito along with Kotlin. I have spent some time today trying to figure out why a project I've been working on fails on Android versions lower than 24, but works fine on API 24+. I find that DexOpener is one of the components that seems to make a difference. We were using 0.10.3 of DexOpener, and the behaviour is slightly different with that version, so I decided to upgrade, and then the behaviour changes quite a bit more.
I have been working on getting this to fail on a smaller, non-proprietary project, and have succeeded. I end up getting the following error when run in an API 23 Emulator:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.robotsandpencils.kotlindaggerexperiement/com.robotsandpencils.kotlindaggerexperiement.presentation.main.MainActivity}: kotlin.UninitializedPropertyAccessException: lateinit property dispatchingActivityInjector has not been initialized

But the same code runs fine in API 24 and higher.
The project is on Github: https://github.com/nealsanche/KotlinDagger2Experiment
I wonder if you might have a look and see if there's anything you can suggest. This project seems to also run fine when using the 0.10.3 version of DexOpener (though my larger proprietary project does not).

Cannot find BuildConfig if applicationId changed for product flavor
Say my source code uses the package name a.b.c
Now I add a couple product flavors, f1 and f2, changing my defaultConfig applicationId to a.b.
f1 adds applicationIdSuffix ".d".
while f2 adds applicationIdSuffix ".c", keeping the original package name.
It turns out that I can run Android tests for the variant f2 but when using f1 I get the IllegalStateException that the BuildConfig can't be found.
My setup is a bit more complicated than this example but this should be enough to illustrate the issue. My BuildConfig class will always be a.b.c.BuildConfig even when the application ID is a.b.d.
The workaround is to use the deprecated Builder to specify the BuildConfig class. I'm expecting this will be inaccessible soon so I'm highlighting that there should still be a way to specify the BuildConfig manually.
Some devices won't run tests: "java.lang.VerifyError: Rejecting class X because it failed compile-time verification"
This is a strange one. I am running the same test package including dexopener on different devices. For some the tests run normally and for others the tests won't start because of this error. Here is the entire output for the test run on one of the failing devices:

We have successes on a Samsung Galaxy S6 Marshmallow, a Google Nexus 6 Lollipop, and a Google Pixel C Nougat.
We have failures on a Samsung Galaxy S7 Marshmallow and an HTC One A9 Marshmallow.
So there doesn't seem to be a pattern of why one device should pass and the other fail.

Using a Spy on TestApplication
Running this code:
DexOpener.install(this)
return Mockito.spy(super.newApplication(cl, "com.xyz.test.TestApp", context))
gives me this error
org.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: class com.xyz.test.TestApp
Do you know any way I can place a spy on my custom Application class so that I can mock some methods on it?
My setup is working when I remove the spy.

Anyway, this whole thing doesn't start until the test starts... in my case it's an Activity test so eventually the rule times out the activity launch at 45 seconds and so we fail.
Running a single instrumentation test on a Marshmallow device using AndroidJUnit4. My app is MultiDex, so here's my test runner:
public class MultiDexJUnitTestRunner extends AndroidJUnitRunner {
@Override
public void onCreate(Bundle arguments) {
MultiDex.install(getTargetContext());
super.onCreate(arguments);
}
@Override
public Application newApplication(ClassLoader cl, String className, Context context)
throws InstantiationException, IllegalAccessException, ClassNotFoundException {
DexOpener.install(this);
return super.newApplication(cl, className, context);
}
}
Though the same symptom happened even if I comment out the MultiDex stuff, so that doesn't seem to be the reason...
RuntimeException occurs when minSdkVersion is 26
Smali does not support Dex format version 038.

Mocking final methods in Android platform classes
Am I correct in understanding that only final classes and methods that are created in our projects can be mocked with this library? I am trying to mock Activity.getApplication(), which is final and isn't normally possible with mockito-android, and it seems that this library isn't able to help there either. I think this limitation is described in the README, "Mockable final classes and methods are restricted under the package of the app's BuildConfig", but that wasn't initially clear to me.
Perhaps this limitation could be clarified in the library's main description. When I read, "A library that provides the ability to mock final classes and methods on Android", I thought it meant any final class or method anywhere (from the platform, a library, etc.).

Exception message in runtime:
Class 'ua.pl.mik.app.DaggerAppComponent$SomeLongNameBuilder' does not implement interface 'ua.pl.mik.app.net.ApiComponent$Builder' in call to 'ua.pl.mik.app.net.ApiComponent ua.pl.mik.app.net.ApiComponent$Builder.build()
Class names was changed a bit.
On Android 7.0+ same apks (main + androidTest) working fine.
Mockito cannot mock/spy final class
Hi, I have a question related with your library. Can I mock classes with are under other modules of my project? For example, projects usually have three modules: view, domain and data. When I run my test, it says that one class from my data module cannot be mocked. I think is related with this:
"The final classes/methods you can mock are only those under the package of your app's BuildConfig. Therefore, you cannot mock final classes/methods you don't own, such as Android system classes and third-party libraries."
But in my case, I do own that classes, but they are in other modules in my project. Is there any way to workaround this?
Having a app crash after Studio 3.0 update

How to deal with package id different from class package
We started long time ago and we didn't have name for app yet. So our main package is com..
Before release, we finalised name of the app and it is stated in our build.gradle. However, package name in sources was not changed.
I'm trying now to use dexopener but I'm getting error from mockito that it can not mock the class.
In addition, it fails to on non final java class and non final method (I would expect it to fail on Kotlin class).
Any help with it?

dalvik.system.DexFile has been deprecated
Unfortunately, dalvik.system.DexFile has been deprecated in Android O.
So the current implementation might not work in the future...
We have to take a careful look at the libcore repository.

Not able to mock static class of third party library
I have tried to mock third party library static class in UI testing that worked very well in android above API 29 without using DexOpener.
For mock static class I have used Mockk Library . In Mockk they suggested to used dexopener library to mock final class before API 29.
When I configure this library and try to run test it fails and log the error not able to mock static class.
Cannot mock final classes declared on on pure Java / Kotlin modules
If you have a class defined on a pure Java or Kotlin library module (not Android) , let's say:core, then you write a UI test on your app module (the android application module) which uses that dependency, dexopener fails.

The test is pretty straight forward and is just using one `mock()` so I'm not sure off the top of my head what could be causing this. Perhaps it's even a machine specific issue?
