Running tests on Android

This is one method to run JS tests from mjsunit, mozilla, test262 test suites with test/tools.py script on Android through 'adb'.

Building d8 shell

For running JS tests executable of d8 stand alone shell is required. Old v8shell is no longer used for executing JS tests.

To build d8 shell under Android build system Android.d8.mk file should be added with following content in v8 root directory:

#

Also add this fix to Android.v8common.mk

Finally, include Android.d8.mk file in Android.mk file.

Build d8 shell with "mm -j4" command.

Run the emulator

Make partition on Android writable in order to push files with command: adb remount

Transfer test files to device

Push the d8, test files from the test suite, and python files form tools directory. For example to transfer mjsunit files and tools files do:

adb push test/mjsunit /tmp/mjsunit

adb push tools /tmp/tools/

Run the test suite

Specific test suite (mjsunit for example) can be run on android device with:

tools/test.py --mode=release --verbose --timeout=480 --arch=mips --report --android --android-push-path /tmp --android-bin-path /tmp mjsunit

Where paths to test suite directory and d8 executable after --android-push-path and --android-bin-path command switches are specified respectively.
