/**
|

* \brief This macro tests the expression passed to it as a test step or
|
||||
* individual test in a test case.
|
||||
*
|
||||
* It allows a library function to return a value and return an error
|
||||
* code that can be tested.
|
||||
*
|
||||
* When MBEDTLS_CHECK_PARAMS is enabled, calls to the parameter failure
|
||||
* callback, MBEDTLS_PARAM_FAILED(), will be assumed to be a test
|
||||
* failure.
|
||||
*
|
||||
* This macro is not suitable for negative parameter validation tests,
|
||||
* as it assumes the test step will not create an error.
|
||||
*
|
||||
* Failing the test means:
|
||||
* - Mark this test case as failed.
|
||||
* - Print a message identifying the failure.
|
||||
* - Jump to the \c exit label.
|
||||
*
|
||||
* This macro expands to an instruction, not an expression.
|
||||
* It may jump to the \c exit label.

/**
|
||||
* \brief This macro tests the statement passed to it as a test step or
|
||||
* individual test in a test case. The macro assumes the test will not fail.
|
||||
*
|
||||
* It assumes the library function under test cannot return a value and
|
||||
* assumes errors can only be indicated by calls to
|
||||
* MBEDTLS_PARAM_FAILED().
|
||||
*
|
||||
* When MBEDTLS_CHECK_PARAMS is enabled, calls to the parameter failure
|
||||
* callback, MBEDTLS_PARAM_FAILED(), are assumed to indicate the
|
||||
* expected failure. If MBEDTLS_CHECK_PARAMS is not enabled, no test
|
||||
* can be made.
|
||||
*
|
||||
* This macro is intended to test that functions returning void
|
||||
* accept all of the parameter values they're supposed to accept - eg
|
||||
* that they don't call MBEDTLS_PARAM_FAILED() when a parameter
|
||||
* that's allowed to be NULL happens to be NULL.
|
||||
*
|
||||
* Note: for functions that return something other that void,
|
||||
* checking that they accept all the parameters they're supposed to
|
||||
* accept is best done by using TEST_ASSERT() and checking the return
|
||||
* value as well.
|
||||
*
|
||||
* Note: this macro is available even when #MBEDTLS_CHECK_PARAMS is
|
||||
* disabled, as it makes sense to check that the functions accept all
|
||||
* legal values even if this option is disabled - only in that case,
|
||||
* the test is more about whether the function segfaults than about
|
||||
* whether it invokes MBEDTLS_PARAM_FAILED().
|
||||
*
|
||||
* \param TEST The test expression to be tested.

|

* You must set \p pointer to \c NULL before calling this macro and
|
||||
* put `mbedtls_free( pointer )` in the test's cleanup code.
|
||||
*
|
||||
* If \p length is zero, the resulting \p pointer will be \c NULL.
|
||||
* This is usually what we want in tests since API functions are
|
||||
* supposed to accept null pointers when a buffer size is zero.
