* Update TEST_ASSERT to do nothing if condition is true The TEST_ASSERT should not return if the condition is true, because: - it prevents the usage of multiple TEST_ASSERT in a single test case, - that behavior differs from how the assert in the standard library works, and thus may give unexpected results. Make the TEST_ASSERT to print an error message (with an formatted optional user part) when it fails to make debugging easier. * Fix some bugs in TestProvider, add unit tests Use pointer-to-vector in TestProvider so writes can be tested, too. * Add test EncodeDecode16, fix some encode16 bugs The function mbedtls_mpi_write_string needs a bit longer buffer than the resulting string actually will be. Known bug: mbedtls_mpi_read_binary ingores initial null bytes * Add test EncodeDecode64, fix some bugs The functions mbedtls_base64_encode and mbedtls_base64_decode needs a bit longer buffer than the resulting string actually will be. * Remove check for empty data from TestProvider It can be valid to get the hash of empty string. * Add tests for CRC calculation Two type of thests: - compare the result of the CRC calculation to a known to be good results, - generate random data as message, calculate of it's CRC and append that to the message, the CRC of this new data should be 0. * Add test for hash algorithms * Add includes in tests * Remove the use of C++20 ranges It seems that Apple Clang does not support range-based constrained algorithms at this time. * Replace encode16 implementation To encode the zero bytes at the begining of the input vector, too.
