+
+Running the manual tests
+------------------------
+
+`recovery-refresh` and `recovery-persist` executables exist only on systems without
+/cache partition. And we need to follow special steps to run tests for them.
+
+- Execute the test on an A/B device first. The test should fail but it will log
+ some contents to pmsg.
+
+- Reboot the device immediately and run the test again. The test should save the
+ contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if
+ this file has expected contents.
+
+`ResourceTest` validates whether the png files are qualified as background text
+image under recovery.
+
+ 1. `adb sync data` to make sure the test-dir has the images to test.
+ 2. The test will automatically pickup and verify all `_text.png` files in
+ the test dir.

+# Steps to regenerate background text images under res-*dpi/images/
+
+1. Build the recovery_l10n app:
+
+ cd bootable/recovery && mma -j32
+
+2. Install the app on the device (or emulator) with the intended dpi.
+
+ * For example, we can use Nexus 5 to generate the text images under
+ res-xxhdpi.
+ * We can set up the maximum width of the final png image in res/layout/main.xml
+ Currently, the image width is 1200px for xxxhdpi, 900px for xxhdpi and
+ 480px for xhdpi/hdpi/mdpi.
+ * When using the emulator, make sure the NDK version matches the current
+ repository. Otherwise, the app may not work properly.
+
+ adb install $PATH_TO_APP
+
+3. Run the app, select the string to translate and press the 'go' button.
+
+4. After the app goes through the strings for all locales, pull the output png
+ file from the device.
+
+ adb root && adb pull /data/data/com.android.recovery_l10n/files/text-out.png
+
+5. Compress the output file put it under the corresponding directory.
+
+ * "pngcrush -c 0 ..." converts "text-out.png" into a 1-channel image,
+ which is accepted by Recovery. This also compresses the image file by
+ ~60%.
+ * zopflipng could further compress the png files by ~10%, more details
+ in https://github.com/google/zopfli/blob/master/README.zopflipng
+ * If you're using other png compression tools, make sure the final text
+ image works by running graphic tests under the recovery mode.
+
+ pngcrush -c 0 text-out.png $OUTPUT_PNG
