Here is what I found but I'm not sure if this is the right way or not. The make process actually prints out the jar name of the junit tests for OpenCV java wrappers (opencv-test.jar). Here is how to run it.

1. Install JRE for your platform. I have Mac so further examples will work for unix and the likes. MS Win I guess works in the similar fashion, just need to use proper path syntax.

2. Navigate to /opencv/build folder and run the following command:

   java -cp ./modules/java/pure_test/.build/lib/junit-4.11.jar:./modules/java/pure_test/.build/build/jar/opencv-test.jar:./bin/opencv-310.jar -Djava.library.path="./lib" junit.textui.TestRunner org.opencv.test.opencv-package-name.test-class-name

opencv-package-name stands for the name of the corresponding opencv module, for example calib3d, core, features2d, highgui, imgproc, objdetect, photo, utils, video etc.

test-class-name can be any class from that package, which inherits from OpenCVTestCase. For example:

java -cp ./modules/java/pure_test/.build/lib/junit-4.11.jar:./modules/java/pure_test/.build/build/jar/opencv-test.jar:./bin/opencv-310.jar -Djava.library.path="./lib" junit.textui.TestRunner org.opencv.test.utils.ConvertersTest

will produce the following output:

OK (41 tests)
