I checked a previous answer about unit test for Android, where it is suggested Googletest as a good option. However, I got a look into the Google C++ Testing Framework - Googlet
jni/Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := foo
LOCAL_SRC_FILES := foo.cpp
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := foo_unittest
LOCAL_SRC_FILES := foo_unittest.cpp
LOCAL_SHARED_LIBRARIES := foo
LOCAL_STATIC_LIBRARIES := googletest_main
include $(BUILD_EXECUTABLE)
$(call import-module,third_party/googletest)
This gradle plugin https://github.com/fsbarata/ndktest-plugin will help you get the Googletest working. Still worth to look at the Googletest framework though.
GoogleTest is now distributed with the NDK (mainly because it's used by the NDK test suite itself).
It's very easy to use in your own projects, see $NDK/sources/third_party/googletest/README.NDK for usage examples.
You need to built Googletest for Android to be able to run it with your toolchain, as you working with cross-compilation.
Download source code of googletest
$ mkdir googletest
$ cd googletest
$ svn checkout http://googletest.googlecode.com/svn/trunk/ .
Copy jni directory to googletest directory
$ cd /path/to/this/git
$ cp -r jni googletest/
run ndk-build script
$ cd googletest/ $ ndk-build
You can find libgtest.a in googletest/obj/local/armeabi/libgtest.a
