The `Timeout` drift test uses rescheduling inside a callback, but it is
currently disabled due to lack of stability. Rescheduling using relative
timeouts inside the callback is a bad technique as it leads to drift, so
I understand the test being disabled. It is better to use `Ticker` for a
periodic callback or to use `Timeout::attach_absolute`.
Add a simpler test that just ensures the callback is called repeatedly -
this test would detect issue #12940, and should not have stability
problems.
Time drifting test cases use serial communication with the host and are unstable on CI.
Skip time-drifting test cases if SKIP_TIME_DRIFT_TESTS macro is defined.
The idea for the future is to use FPGA test shield for timing tests instead of host scripts.
Also remove `__ARM_FM` macro which in most cases was used to disable time drifting tests. In other cases replace `__ARM_FM` with `TARGET_ARM_FM` which is more suitable.
Increase the Timeout period from 1ms to 10ms so interrupt latency has
1/10th the effect on the measurement. This prevents failures due to
interrupt latency causing a drift.
1) mbed-os-tests-mbedmicro-rtos-mbed-basic tests use to fail when run in loop
after 20-25, This was because the stack used by test application was in range of
744-840 bytes. So bumped the stack size to 1024 bytes.
2) Corrected the assert and taken out the assert which was not required.
In the new approach the host controls the device activity when the test
should start, finish and pass/fail status is send to device. Also deprecate
the test cases which can't accurately test.
This commit adds the following test frameworks:
- `greentea-client` (https://github.com/ARMmbed/greentea-client)
- This framework provides a key-value api for communicating with the
greentea test tool (https://github.com/ARMmbed/greentea)
- `unity` (https://github.com/ARMmbed/unity)
- This framework provides test assert macros that can be used when
writing test cases
- `utest` (https://github.com/ARMmbed/utest)
- This framework allows you to execute a series of test cases with
reporting that works with the greentea test tool
(https://github.com/ARMmbed/greentea)
The following changes were made when bringing these frameworks into the
tree:
- References to `mbed_drivers/mbed.h` within utest's tests were migrated
to `mbed.h`
- The yotta file `module.json` was removed from `greentea-client` and
`unity`
- `coverage.json` was also removed from `greentea-client`
- `.gitignore` and `.gitattributes` were removed from `greentea-client`
- Apache 2.0 license files were removed from `greentea-client`
This also brings in a number of tests that have been newly written or ported from various sources:
- `TESTS/integration` - Very basic tests, used to check if testing frameworks are working correctly
- `TESTS/mbed_drivers` (Thanks @PrzemekWirkus!) - TESTS ported from mbed OS 3.0 (https://github.com/ARMmbed/mbed-drivers)
- `TESTS/mbedmicro-mbed` (Thanks @PrzemekWirkus!) - Tests that weren't covered by `TESTS/mbed_drivers` that currently live in `libraries/tests/mbed`
- `TESTS/mbedmicro-rtos-mbed` (Thanks @PrzemekWirkus!) - Ported tests that currently live in `libraries/tests/rtos/mbed`
- `TESTS/storage_abstraction` (Thanks @rgrover!) - Tests for the storage_abstraction hal
