1 # Android Test Instructions
3 Device Setup Tests are runnable on physical devices or emulators. See the
4 instructions below for setting up either a physical device or an emulator.
8 ## Physical Device Setup **ADB Debugging**
10 In order to allow the ADB to connect to the device, you must enable USB
13 * Before Android 4.1 (Jelly Bean):
14 * Go to "System Settings"
15 * Go to "Developer options"
16 * Check "USB debugging".
17 * Un-check "Verify apps over USB".
18 * On Jelly Bean, developer options are hidden by default. To unhide them:
20 * Tap 10 times on "Build number"
21 * The "Developer options" menu will now be available.
22 * Check "USB debugging".
23 * Un-check "Verify apps over USB".
27 You MUST ensure that the screen stays on while testing: `adb shell svc power
28 stayon usb` Or do this manually on the device: Settings -> Developer options
31 If this option is greyed out, stay awake is probably disabled by policy. In that
32 case, get another device or log in with a normal, unmanaged account (because the
33 tests will break in exciting ways if stay awake is off).
37 adb shell setprop debug.assert 1
39 ### Disable Verify Apps
41 You may see a dialog like
42 [this one](http://www.samsungmobileusa.com/simulators/ATT_GalaxyMega/mobile/screens/06-02_12.jpg),
43 which states, _Google may regularly check installed apps for potentially harmful
44 behavior._ This can interfere with the test runner. To disable this dialog, run:
45 `adb shell settings put global package_verifier_enable 0`
51 Use an emulator (i.e. Android Virtual Device, AVD): Enabling Intel's
52 Virtualizaton support provides the fastest, most reliable emulator configuration
53 available (i.e. x86 emulator with GPU acceleration and KVM support).
55 1. Enable Intel Virtualization support in the BIOS.
57 2. Set up your environment:
60 . build/android/envsetup.sh
63 3. Install emulator deps:
66 build/android/install_emulator_deps.py --api-level=19
69 This script will download Android SDK and place it a directory called
70 android\_tools in the same parent directory as your chromium checkout. It
71 will also download the system-images for the emulators (i.e. arm and x86).
72 Note that this is a different SDK download than the Android SDK in the
73 chromium source checkout (i.e. src/third\_party/android\_emulator\_sdk).
75 4. Run the avd.py script. To start up _num_ emulators use -n. For non-x86 use
79 build/android/avd.py --api-level=19
82 This script will attempt to use GPU emulation, so you must be running the
83 emulators in an environment with hardware rendering available. See
84 `avd.py --help` for more details.
88 Alternatively, you can create an run your own emulator using the tools provided
89 by the Android SDK. When doing so, be sure to enable GPU emulation in hardware
90 settings, since Chromium requires it to render.
94 It may not be immediately obvious where your test code gets compiled to, so here
95 are some general rules:
97 * If your test code lives under /content, it will probably be built as part of
98 the content_shell_test_apk
99 * If your test code lives under /chrome (or higher), it will probably be built
100 as part of the chrome_public_test_apk
101 * (Please fill in more details here if you know them).
103 NB: We used to call the chrome_public_test_apk the
104 chromium_shell_test_apk. There may still be references to this kicking
105 around, but wherever you see chromium_shell_test you should replace with
108 Once you know what to build, just do it like you normally would build anything
109 else, e.g.: `ninja -C out/Release chrome_public_test_apk`
113 All functional tests are run using `build/android/test_runner.py`.
114 Tests are sharded across all attached devices. In order to run tests, call:
115 `build/android/test_runner.py <test_type> [options]`
116 For a list of valid test types, see `test_runner.py --help`. For
117 help on a specific test type, run `test_runner.py <test_type> --help`.
119 The commands used by the buildbots are printed in the logs. Look at
120 http://build.chromium.org/ to duplicate the same test command as a particular
123 If you build in an output directory other than "out", you may have to tell
124 test\_runner.py where you place it. Say you build your android code in
125 out\_android, then do `export CHROMIUM_OUT_DIR=out_android` before running the
128 ## INSTALL\_FAILED\_CONTAINER\_ERROR or INSTALL\_FAILED\_INSUFFICIENT\_STORAGE
130 If you see this error when test\_runner.py is attempting to deploy the test
131 binaries to the AVD emulator, you may need to resize your userdata partition
132 with the following commands:
135 # Resize userdata partition to be 1G resize2fs
136 android_emulator_sdk/sdk/system-images/android-19/x86/userdata.img 1G
138 # Set filesystem parameter to continue on errors; Android doesn't like some
139 # things e2fsprogs does.
141 android_emulator_sdk/sdk/system-images/android-19/x86/userdata.img
144 ## Symbolizing Crashes
146 Crash stacks are logged and can be viewed using adb logcat. To symbolize the
147 traces, pipe the output through
148 `third_party/android_platform/development/scripts/stack`. If you build in an
149 output directory other than "out", pass
150 `--chrome-symbols-dir=out_directory/{Debug,Release}/lib` to the script as well.
156 ninja -C out/Release content_unittests_apk
159 build/android/test_runner.py gtest -s content_unittests --release -vvv
161 # Run a subset of tests
162 build/android/test_runner.py gtest -s content_unittests --release -vvv \
163 --gtest-filter ByteStreamTest.*
166 ## Instrumentation Tests
168 In order to run instrumentation tests, you must leave your device screen ON and
169 UNLOCKED. Otherwise, the test will timeout trying to launch an intent.
170 Optionally you can disable screen lock under Settings -> Security -> Screen Lock
173 Next, you need to build the app, build your tests, install the application APK,
174 and then run your tests (which will install the test APK automatically).
181 # Build the code under test
182 ninja -C out/Release content_shell_apk
184 # Build the tests themselves
185 ninja -C out/Release content_shell_test_apk
187 # Install the code under test
188 build/android/adb_install_apk.py out/Release/apks/ContentShell.apk
190 # Run the test (will automagically install the test APK)
191 build/android/test_runner.py instrumentation --test-apk=ContentShellTest \
192 --isolate-file-path content/content_shell_test_apk.isolate --release -vv
198 # Build the code under test
199 ninja -C out/Release chrome_public_apk
201 # Build the tests themselves
202 ninja -C out/Release chrome_public_test_apk
204 # Install the code under test
205 build/android/adb_install_apk.py out/Release/apks/ChromePublic.apk
207 # Run the test (will automagically install the test APK)
208 build/android/test_runner.py instrumentation --test-apk=ChromePublicTest \
209 --isolate-file-path chrome/chrome_public_test_apk.isolate --release -vv
212 AndroidWebView tests:
215 ninja -C out/Release android_webview_apk
216 ninja -C out/Release android_webview_test_apk
217 build/android/adb_install_apk.py out/Release/apks/AndroidWebView.apk \
218 build/android/test_runner.py instrumentation --test-apk=AndroidWebViewTest \
219 --test_data webview:android_webview/test/data/device_files --release -vvv
222 Use adb\_install\_apk.py to install the app under test, then run the test
223 command. In order to run a subset of tests, use -f to filter based on test
224 class/method or -A/-E to filter using annotations.
230 build/android/test_runner.py instrumentation --test-apk=ContentShellTest
232 # Run a specific test class
233 build/android/test_runner.py instrumentation --test-apk=ContentShellTest -f \
236 # Run a specific test method
237 build/android/test_runner.py instrumentation --test-apk=ContentShellTest -f \
238 AddressDetectionTest#testAddressLimits
240 # Run a subset of tests by size (Smoke, SmallTest, MediumTest, LargeTest,
242 build/android/test_runner.py instrumentation --test-apk=ContentShellTest -A \
245 # Run a subset of tests by annotation, such as filtering by Feature
246 build/android/test_runner.py instrumentation --test-apk=ContentShellTest -A \
250 You might want to add stars `*` to each as a regular expression, e.g.
251 `*`AddressDetectionTest`*`
253 ## Running Blink Layout Tests
256 https://sites.google.com/a/chromium.org/dev/developers/testing/webkit-layout-tests
260 (e.g. the "Android Debug (Nexus 7)" bot on the chromium.gpu waterfall)
262 See http://www.chromium.org/developers/testing/gpu-testing for details. Use
263 --browser=android-content-shell. Examine the stdio from the test invocation on
264 the bots to see arguments to pass to src/content/test/gpu/run\_gpu\_test.py.
