Oboe Unit Tests

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

The basic operation is:

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

Prerequisites/caveats

1. Java JDK installed.
2. On Mac, you must agree to the XCode license. The script will prompt you.
3. You must have compiled and executed one of the Oboe examples or OboeTester. That ensures that the NDK and cmake is installed.
4. 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

or this may work on Linux:

export ANDROID_HOME=$HOME/Android/Sdk

Now we need to determine the latest installed version of the NDK. Enter:

ls $ANDROID_HOME/ndk

Make note of the folder name. Mine was “21.3.6528147” so I entered:

export ANDROID_NDK=$ANDROID_HOME/ndk/21.3.6528147/

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 “3.10.2.4988404” so I entered:

export PATH=$PATH:$ANDROID_HOME/cmake/3.10.2.4988404/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
