Googletest for Android NDK

Question

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 - Googletest. About platforms, I don't see anything mentioning support to Android. Could someone tell anything, if there is some way of using it with Android devices - e.g. steps to build a toolchain, etc?

Answer 1

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

Answer 2

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.

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.
