                ##__VA_ARGS__)

Assert that a is greater than or equal to l and less than or equal to u.

Parameters

a	Value to compare
l	Lower limit

			b,
			...
	)		zassert((a) == (b), #a " not equal to " #b, ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that a equals b.

a and b won't be converted and will be compared directly.

Parameters

a	Value to compare
b	Value to compare
...	Optional message and variables to print if the assertion fails

zassert_equal_ptr

#define zassert_equal_ptr	(		a,
			b,
			...
	)		zassert((void *)(a) == (void *)(b), #a " not equal to " #b, ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that a equals b.

a and b will be converted to void * before comparing.

Parameters

a	Value to compare
b	Value to compare
...	Optional message and variables to print if the assertion fails

zassert_false

#define zassert_false	(		cond,
			...
	)		zassert(!(cond), #cond " is true", ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that cond is false.

Parameters

cond	Condition to check
...	Optional message and variables to print if the assertion fails

zassert_is_null

#define zassert_is_null	(		ptr,
			...
	)		zassert((ptr) == NULL, #ptr " is not NULL", ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that ptr is NULL.

Parameters

ptr	Pointer to compare
...	Optional message and variables to print if the assertion fails

zassert_mem_equal

#define zassert_mem_equal

(

...

)

zassert_mem_equal__(__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that 2 memory buffers have the same contents.

This macro calls the final memory comparison assertion macro. Using double expansion allows providing some arguments by macros that would expand to more than one values (ANSI-C99 defines that all the macro arguments have to be expanded before macro call).

Parameters

...	Arguments, see zassert_mem_equal__ for real arguments accepted.

zassert_mem_equal__

#define zassert_mem_equal__	(		buf,
			exp,
			size,
			...
	)		zassert(memcmp(buf, exp, size) == 0, #buf " not equal to " #exp, ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Internal assert that 2 memory buffers have the same contents.

Note

This is internal macro, to be used as a second expansion. See zassert_mem_equal.

Parameters

buf	Buffer to compare
exp	Buffer with expected contents
size	Size of buffers
...	Optional message and variables to print if the assertion fails

zassert_not_equal

#define zassert_not_equal	(		a,
			b,
			...
	)		zassert((a) != (b), #a " equal to " #b, ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that a does not equal b.

a and b won't be converted and will be compared directly.

Parameters

a	Value to compare
b	Value to compare
...	Optional message and variables to print if the assertion fails

#define zassert_not_null	(		ptr,
			...
	)		zassert((ptr) != NULL, #ptr " is NULL", ##__VA_ARGS__)

#include <subsys/testsuite/ztest/include/zephyr/ztest_assert.h>
