AndroidTestUtilities
------------------------

.. 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
