.. versionadded:: 3.7
|
|
|
|
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
|
|
|
|
.. code-block:: cmake
|
|
|
|
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
|
|
