The reasoning behind this commit is twofold:
1. test the "lower" part (the device part) of netdev
2. provide a well defined testing infrastructure for modules that utilise
netdev
The actual tests that represent 1. are provided in the following commit
Changing between branches in git typically leaves directories empty and
does not remove them. If you have different unittests in different
branches this leads to an error in building them, since the current
configuration expects a Makefile in all `tests-*` directory. This change
configures Make to search for a Makefile in `tests-*` rather than just
assuming that there is one.
This is a malloc-free implementation of the Concise Binary Object
Representation (CBOR) data format for the RIOT-OS.
This implementation mostly stand-alone, and it should be pretty easy to
port to other platforms. We're only using the C STL and some custom
network-related functionaliy which could be easily replaced by depending
on arpa/inet.h.
The CBOR API is straight-forward to use and provides encoding/decoding
functionality for all major C types, such as:
- int
- uint64_t
- int64_t
- float
- double
- char*
- struct tm
- time_t
It is possible to conditionally compile this module via CFLAGS:
- CBOR_NO_SEMANTIC_TAGGING: All semantic-tagging features removed
- CBOR_NO_CTIME: All ctime related features removed
- CBOR_NO_FLOAT: All floating-point related features removed
- CBOR_NO_PRINT: All features depending on printf removed
This change removes the need to patch the main.c if you add or remove a
test suite. A test suite in `tests/unittests/tests-XXX` needs to export
the function `void tests_XXX(void)`, which gets called by `main()`.
The `tests-XXX/Makefile` looks like your average module:
```
MODULE = tests-XXX
include $(RIOTBASE)/Makefile.base
```
Unittests for e.g. different libraries can be put into
`tests/unittests/tests-XXX`, where `XXX` is your test suite.
If `unittests` is made with `make all` (or any explicit argument), then
all test suites get built. If you use `make tests-XXX tests-YYY …` then
only the test suites `XXX` and `YYY` get built.
