Oboe Unit Tests

This directory contains the Oboe unit tests. They are run using the bash script run_tests.sh.

The basic operation is:

Connect an Android device or start the Android emulator
Open a terminal window and execute run_tests.sh

Prerequisites/caveats

You must have compiled and executed one of the Oboe examples or OboeTester. That ensures that the NDK and cmake is installed.

You must define ANDROID_NDK as an environment variable and make sure cmake is on your path.

To test this on Mac or Linux enter:

echo $ANDROID_HOME
echo $ANDROID_NDK
cmake --version

They may already be set. If not, then this may work on Mac OS:

export ANDROID_HOME=$HOME/Library/Android/sdk
export ANDROID_NDK=$ANDROID_HOME/ndk-bundle

or this may work on Linux:

export ANDROID_HOME=$HOME/Android/Sdk
ls $ANDROID_HOME/ndk

Make note of the folder name. Mine was "21.0.6113669" so I entered:

export ANDROID_NDK=$ANDROID_HOME/ndk/21.0.6113669/

If you need to add cmake to your path then you can find it by entering:

ls $ANDROID_HOME/cmake

Make note of the folder name. Mine was "3.6.4111459" so I entered:

export PATH=$PATH:$ANDROID_HOME/cmake/3.6.4111459/bin
cmake --version

Running the Tests

To run the tests, enter:

cd tests
./run_tests.sh

You may need to enter <control-c> to exit the script.

If you get this error:

com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException:
    INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.google.oboe.tests.unittestrunner
    signatures do not match previously installed version; ignoring!

then uninstall the app "UnitTestRunner" from the Android device.

See run_tests.sh for more documentation
