The timing host tests reported success even if the total drift was
negative. This adds a check for this now.
The wait_us test now does not use a timer and just waits for 100000 us
between prints. This adds inherent drift, but it should still be well
under the limit.
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
