Individual libraries' `target_h` stub headers have now all been moved
from `mbed-headers-base` to `mbed-headers-<library>`.
Note: Even though headers previously in `target_h` are technically
stubs/fakes too, they are used by not only unit tests but also regular
libraries when compiled for unit tests, because no target-specific HAL
implementation exists in this case. In order for regular library
sources to pick up `target_h` headers, those headers must
* have the same names as regular headers
* appear first in include paths
This is why those headers are part of `mbed-headers-<library>` and not
`mbed-stubs-<library>`. Before this refactoring, `mbed-headers-base`
was the first in unit tests' include paths.
We failed to set `LoRaMac_stub::mlme_ind_ptr` to a valid pointer. When
we tried to dereference it in `LoRaWANStack::process_reception` we hit a
SEGFAULT.
This test was relying on the state of `LoRaMac_stub::bool_true_counter`
to be set to 1 from a previous test. When the test was ran in isolation
the `LoRaWANStack::rx_timeout_interrupt_handler` callback would fail
because we weren't returning true from the stub implementation of
`LoRaMac::nwk_joined`. Due to this
`LoRaWANStack::post_process_tx_no_reception` was never called. This
caused the LoRaWANStack object to think the "tx_metadata" was "stale"
(i.e the data hadn't changed since any previous read). So, when we
attempted to call `LoRaWANStack::acquire_tx_metadata` it returned
`LORAWAN_STATUS_METADATA_NOT_AVAILABLE` as it thought we had no new
metadata to report, causing the test assertion to fail.
We had commented out a line where we reset LoRaPHY_stub::uint16_value to
0. This was causing an invalid array access in
LoRaMac::handle_data_frame, when trying to extract the
_mps_indication.channel from list of channel_params_t returned by
lora_phy->get_phy_channels.
Previously a test executable was recognised as a single test by CTest.
However, test executables usually contain multiple test cases, the
results of the test cases should be individually reported. With our
previous setup we could miss test case failures that didn't cause the
executable to return an error code.
This commit uses gtest_discover_test to discover all test cases in a
test executable. This enables CTest to match test passes and failures
from the googletest binary output.
We previously made up an invalid message type, which was roughly
`MCPS_MULTICAST | 0x40`. This causes an MBED_ASSERT failure in the
handle_rx function, as it uses an assert to validate the message type
passed to it (in convert_to_msg_flag()). Use the valid message type
MCPS_MULTICAST instead in the handle_rx unit test.
To quote @LDong-Arm - "The CMake target `mbed-headers` brings in all
headers, and we are gradually moving away from it and explicitly use
only headers needed by each unit test."
Update netsocket and lorawan unit tests to link with a mbed-stubs-mbedtls
library that it depends on instead of link with mbed-stubs
which is a group of stubs libraries.
Move the connectivity mbedtls stubs into the connectivity/mbedtls
component directory. So we can avoid duplicating the mbed-os source
tree in a central UNITTESTS folder.
Previously all the lorawan stubs headers under mbed-stubs-headers,
so this PR move all lorawan stubs headers under
cellular/tests/UNITTESTS/double directory and update CMake to include
stubs headers into mbed-stubs-lorawan library to make lorawan stubs to be self-contained
Previously the connectivity lorawan stub library depended on
`mbed-headers`, which is a collection of all available headers
in mbed-os. To make it easier to separate the library, only depend
on the headers we're using.
Update lorawan unit test to link only with a mbed-headers-lorawan
library that it depends on instead of link with mbed-headers
which is a group of headers libraries.
Previously, all lorawan headers made as a part of the
mbed-headers-connectivity library. To make it easier to separate all
the lorawan headers into the separate mbed-headers-lorawan library
and keep them, as part of lorawan stubs CMake. This makes the lorawan
stubs more self-contained and improves the composition of the library.

- Previously all cellular header made as a part of the
mbed-headers-connectivity library. To make it easier to separate all
the cellular headers into the separate mbed-headers-cellular library
and keep them as part of cellular stub CMake. This makes the cellular
stubs more self-contained and improves the composition of the library.
- Update all unit test that depends on cellular headers with mbed-headers-cellular library
Assumption that greentea test file is always named main.cpp is
incorrect. Updated mbed_greentea_add_test() macro to make TEST_SOURCES
parameter compulsory, which is used to specify greentea test
file(s). This allows tests to use C, or have a different name.
Therefore also updated all pre-existing greentea test CMake files to
explicity add main.cpp to TEST_SOURCES.
Adding mbed-os subdirectories that are not required for a specific project to .mbedignore is a good way to reduce compilation time. Sometimes it happens that tests depend on ignored files, which causes the test-build to fail even though the corresponding feature/component
is not configured. The reason is that the conditional that skips the test is placed after the includes.
Many test stub functions are meant to return a value, but weren't. Clang
would generate a warning for each instance where we weren't returning
anything in a function that was meant to return a value.
warning: non-void function does not return a value [-Wreturn-type]
For a specific example, my_radio::time_on_air() is supposed to return a
uint32_t, but wasn't returning anything. We'll return a zero instead of
relying on undefined behavior.
Without this, clang 11.0.1 was generating a virtual function
implementation with a `ud2` instruction to abort at run-time, causing
some execution of some unit tests to abort.

- Remove redundant cmake script as already added the CMake configuration file
- Remove redundant empty_baseline as it is no longer needed with the help of CMake configuration file
