I am a Beginner in Android. I want to write a unit testing code in Android studio. How to run that testing in real device and also how to get the test result. I can able to see AndroidTest folder in src folder.
It is a good practice to write Unit Test code from scratch. But if you have learned a little bit of Unit testing basic you can take advantage of IntelliJ plugins for Android Studio to generate Unit Testing code very easily.
Try this:
TestMe(https://plugins.jetbrains.com/plugin/9471-testme)
Auto Generate Unit Tests for source class in Java or Groovy.
No more boilerplate!
Features:
Auto-generate Java or Groovy test code with JUnit 4/5, TestNG or Spock frameworks
Auto-generate Mockito mocks
Generate test params and assertion statements

I have one project(android and iOS) where I am sharing the common code inside shared folder. I have written both unit tests under commonTest(unit-test) folder as well as Instrumentation test inside androidTest(instrumentation test) folder. It works well when I run individual test. But I want to see the coverage also. While I can do this "run with test coverage" for commonTest but it's not available for androidTest. Any tool that will be helpful here. I tried searching and tried few stuffs with jacoco and kover but could not help.
Colleagues,
I am having hard time to find a library/framework/etc... which could help me to generate unit tests in Android.
I know that in Java there are multiple solutions, which could generate unit tests based on the source code. Are you using anything like this for Android?
(My project if fully written in Java).
Use just JUNIT - this should help :
https://developer.android.com/training/testing/unit-testing/local-unit-tests
Use Unit Test Architect
I am in the same boat as you were/are. Although TDD should be the approach for writing tests, but there may be a lot of untested code already written many times in larger projects.
One day I got frustrated with writing test cases of existing, older codebase. Hence, I thought of auto generating all the unit test cases.
I have created an Open-source Gradle Plugin which can be used for the above task. It is already hosted on mavenCentral. I have used it to generate test cases for my projects. But it can be used in any gradle project, (android, java, kotlin, kotlin+java). It may be rough around the edges but it has done it's job well for me.
BuildScript Dependency:
classpath "io.github.orange-3:unit-test-architect:$PLUGIN_VERSION"
I want to use Junit & Mockito for android framework java files for local unit testing.
I am not using android studio and want to write these unit testcases and execute them on Linux server.
I have used libraries Junit, Mockito , hamcrest-core jar files. Do I need to include any other jar files?
I am stuck at mocking the context.
#Mock Context context - Doesn't work at all
Can anyone please guide me on this?
I am creating the unit test for some legacy android codes.
Currently i need to manually create the unit test for each class/method in test/java.
Is there an automated way to auto generate all the test stubs? ideally from the Android studio IDE? (similar to how parasoft can autogenerate empty test stubs for C++ classes and methods).
I am using robolectric on Android studio 1.2.1
Like this: Right-click the class name. Go To -> Test. Select the function, Done.
I want to run some JUnit4 tests. The code relies on some Android libraries(Android XML parser), but does not create any activites and so on. When I try to run tests I got that an Android class that I need was not found. Is there any way to run JUnit4 tests with Android code, not to test activity but to test code with some libraries.
I had the same problem and tried to adapt JUnit4 to Android's existing TestRunner - without success. Therefore I created a new project called JUnit4Android. It's a TestRunner application library for JUnit4 and JUnit3 tests and test suites. So you can run your existing JUnit4 tests with it. Please find more information on GitHub:
https://github.com/dthommes/JUnit4Android/wiki
There is no way (that I'm aware of) to use JUnit4 on Android. It does support JUnit3 though, if that's an option for you?
Alternatively, you could use Robolectric and run your tests on your development machine (where you'll be able to use whichever unit test framework you like). Whether this will work for you depends on exactly what you're testing, but it might be worth a go?
It might be little bit late, but there's finally an official update from Google about junit4:
based on Android-test-kit project and some other sources it's clear that:
The AndroidJUnitRunner is a new unbundled test runner for Android, which is part of the
Android Support Test Library and can be downloaded via the Android
Support Repository. The new runner contains all improvements of
GoogleInstrumentationTestRunner and adds more features:
- JUnit4 support
- Instrumentation Registry for accessing Instrumentation, Context and Bundle Arguments
- Test Filters #SdkSupress and #RequiresDevice
- Test timeouts
- Sharding of tests
- RunListener support to hook into the test run lifecycle
- Activity monitoring mechanism ActivityLifecycleMonitorRegistry
Actually, it's already presented in Support Repository. If You go to
%ANDROID_HOME%\extras\android\m2repository\com\android\support\test\testing-support-lib\
it's possible to find testing-support-lib in there (aar, jars etc.) which allows to use JUnit4. Even more, it contains espresso library same location which is handy for UI testing. Seems Android sites and support lib official references will be updated soon with that info.
