1. Open the Eclipse, create a new workspace and select a path to Android SDK: Eclipse Menu → Window → Preferences → Android → SDK Location.
2. Import the OpenCV Java API project (OpenCV project):
   • Select Eclipse Menu → File → Import → General → Existing project into Workspace.
   • Select root directory — point Eclipse to your opencv_trunk/android/build (or opencv_trunk/android/build_armeabi folder)
   • Press Finish
3. Import the OpenCV Java API Test project (Test project):
   • Select Eclipse Menu → File → Import → General → Existing project into Workspace
   • Select root directory — point Eclipse to your opencv_trunk/modules/java/android_test
   • Press Finish
4. For Test project set the reference to OpenCV project: Project properties → Android → Library → Add and point to OpenCV project.
5. Fix project properties: Eclipse Menu → Project → Build All, Eclipse Menu → Project → Clean, F5.
6. Right click on Test project and choose Run as → Android JUnit Test.

• Tests in repository: http://github.com/opencv/opencv/tree/master/modules/java/android_test
• class OpenCVTestCase has/implements the all stuff needed for OpenCV testing
  • all the OpenCV test classes are subclasses of OpenCVTestCase
  • test_1 (candidate for termination) is for adb log formatting, it allows separate tests from different modules.
• Each OpenCV module has a major test class with static methods: coreTest, imgprocTest, …
• Some OpenCV classes also have their own test class: MatTest

If you want more details, just open the code in Eclipse. Its self-documented ;)

• If you have built OpenCV, you can find apk with tests in opencv_trunk/android/build/bin directory.
• Working folder for test application on device /data/data/org.opencv.test/files.
• How to work with tests from command line: http://developer.android.com/guide/developing/testing/testing_otheride.html.
  

  
  
  adb uninstall org.opencv.test
  
  adb install bin/opencv_test_java.apk
  
  adb shell am instrument -w org.opencv.test/.OpenCVTestRunner
  
  

Show all errors and failures except “Not yet implemented”

adb shell am instrument -w org.opencv.test/.OpenCVTestRunner | grep -E "junit.frameworklException" -A4 | sed -e '/Not yet implemented/,+5d'

To run modules independently

adb shell am instrument -w -e package org.opencv.test.core org.opencv.test/.OpenCVTestRunner
adb shell am instrument -w -e package org.opencv.test.imgproc org.opencv.test/.OpenCVTestRunner
...
adb shell am instrument -w -e package org.opencv.test.<MODULE_NAME> org.opencv.test/.OpenCVTestRunner

Running the whole test package:

python run.py . -a -t java

Running tests for specific module:

python run.py . -a -t java —package .core

• JUnit window allows you to run a single test or tests from one test class (coreTest, imgprocTest). This is useful during the test development.
  • you can call them from JUnit view pane
  • from source code: right click on test method name
• Ctrl + F11 will run opened test case
• Linux tips
  • Calculate test coverage
    

    
    
    (cd android/build && python ../../modules/java/check-tests.py ./src ../../modules/java/android_test/src)
    
    

  • Build tests only
    

    
    
    make -j8 opencv_test_java_android_project
    
    

  • To get blacklist, run
    

    
    
    find -name “*.java” | xargs grep XXX
