gh-116622: Add Android test script (#121595)
Adds a script for running the test suite on Android emulator devices. Starting with a fresh install of the Android Commandline tools; the script manages installing other requirements, starting the emulator (if required), and retrieving results from that emulator.

||||
## Testing
|
||||
|
||||
To run the Python test suite on Android:
|
||||
The tests can be run on Linux, macOS, or Windows, although on Windows you'll
|
||||
have to build the `cross-build/HOST` subdirectory on one of the other platforms
|
||||
and copy it over.
|
||||
|
||||
* Install Android Studio, if you don't already have it.
|
||||
* Follow the instructions in the previous section to build all supported
|
||||
architectures.
|
||||
* Run `./android.py setup-testbed` to download the Gradle wrapper.
|
||||
* Open the `testbed` directory in Android Studio.
|
||||
* In the *Device Manager* dock, connect a device or start an emulator.
|
||||
Then select it from the drop-down list in the toolbar.
|
||||
* Click the "Run" button in the toolbar.
|
||||
* The testbed app displays nothing on screen while running. To see its output,
|
||||
open the [Logcat window](https://developer.android.com/studio/debug/logcat).
|
||||
The test suite can usually be run on a device with 2 GB of RAM, though for some
|
||||
configurations or test orders you may need to increase this. As of Android
|
||||
Studio Koala, 2 GB is the default for all emulators, although the user interface
|
||||
may indicate otherwise. The effective setting is `hw.ramSize` in
|
||||
~/.android/avd/*.avd/hardware-qemu.ini, whereas Android Studio displays the
|
||||
value from config.ini. Changing the value in Android Studio will update both of
|
||||
these files.
|
||||
|
||||
To run specific tests, or pass any other arguments to the test suite, edit the
|
||||
command line in testbed/app/src/main/python/main.py.
|
||||
Before running the test suite, follow the instructions in the previous section
|
||||
to build the architecture you want to test. Then run the test script in one of
|
||||
the following modes:
|
||||
|
||||
* In `--connected` mode, it runs on a device or emulator you have already
|
||||
connected to the build machine. List the available devices with
|
||||
`$ANDROID_HOME/platform-tools/adb devices -l`, then pass a device ID to the
|
||||
script like this:
|
||||
|
||||
```sh
|
||||
./android.py test --connected emulator-5554
|
||||
```
|
||||
|
||||
* In `--managed` mode, it uses a temporary headless emulator defined in the
|
||||
`managedDevices` section of testbed/app/build.gradle.kts. This mode is slower,
|
||||
but more reproducible.
|
||||
|
||||
We currently define two devices: `minVersion` and `maxVersion`, corresponding
|
||||
to our minimum and maximum supported Android versions. For example:
|
||||
|
||||
```sh
|
||||
./android.py test --managed maxVersion
|
||||
```
|
||||
|
||||
By default, the only messages the script will show are Python's own stdout and
|
||||
stderr. Add the `-v` option to also show Gradle output, and non-Python logcat
|
||||
messages.
|
||||
|
||||
Any other arguments on the `android.py test` command line will be passed through
|
||||
to `python -m test` – use `--` to separate them from android.py's own options.
|
||||
See the [Python Developer's
|
||||
Guide](https://devguide.python.org/testing/run-write-tests/) for common options
|
||||
– most of them will work on Android, except for those that involve subprocesses,
|
||||
such as `-j`.
|
||||
|
||||
Every time you run `android.py test`, changes in pure-Python files in the
|
||||
repository's `Lib` directory will be picked up immediately. Changes in C files,
|
||||
and architecture-specific files such as sysconfigdata, will not take effect
|
||||
until you re-run `android.py make-host` or `build`.
