AndroidTestUtilities
------------------------
Create a test that automatically loads specified data onto an Android device.
Introduction
^^^^^^^^^^^^
Use this module to push data needed for testing an Android device behavior
onto a connected Android device. The module will accept files and libraries as
well as separate destinations for each. It will create a test that loads the
files into a device object store and link to them from the specified
destination. The files are only uploaded if they are not already in the object
store.
For example:
.. code-block:: cmake
include(AndroidTestUtilities)
android_add_test_data(
example_setup_test
FILES <files>...
LIBS <libs>...
DEVICE_TEST_DIR "/data/local/tests/example"
DEVICE_OBJECT_STORE "/sdcard/.ExternalData/SHA"
)
At build time a test named "example_setup_test" will be created. Run this test
on the command line with :manual:`ctest(1)` to load the data onto the Android
device.
Module Functions
^^^^^^^^^^^^^^^^
.. command:: android_add_test_data
::
android_add_test_data(<test-name>
[FILES <files>...] [FILES_DEST <device-dir>]
[LIBS <libs>...] [LIBS_DEST <device-dir>]
[DEVICE_OBJECT_STORE <device-dir>]
[DEVICE_TEST_DIR <device-dir>]
[NO_LINK_REGEX <strings>...]
)
The ``android_add_test_data`` function is used to copy files and libraries
needed to run project-specific tests. On the host operating system, this is
done at build time. For on-device testing, the files are loaded onto the
device by the manufactured test at run time.
This function accepts the following named parameters:
``FILES <files>...``
zero or more files needed for testing
``LIBS <libs>...``
zero or more libraries needed for testing
``FILES_DEST <device-dir>``
absolute path where the data files are expected to be
``LIBS_DEST <device-dir>``
absolute path where the libraries are expected to be
``DEVICE_OBJECT_STORE <device-dir>``
absolute path to the location where the data is stored on-device
``DEVICE_TEST_DIR <device-dir>``
absolute path to the root directory of the on-device test location
``NO_LINK_REGEX <strings>...``
list of regex strings matching the names of files that should be
copied from the object store to the testing directory
