#include </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Value:
zassert(((a) >= (l)) && ((a) <= (u)), #a " not between " #l " and " #u " inclusive", \
##__VA_ARGS__)
#define zassert(cond, default_msg,...)
Definition: ztest_assert.h:188

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

Parameters
aValue to compare
lLower limit
uUpper limit
...Optional message and variables to print if the assertion fails

◆ zassert_equal

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

#include </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/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
aValue to compare
bValue 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 </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that a equals b.

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

Parameters
aValue to compare
bValue 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 </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that cond is false.

Parameters
condCondition 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 </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/subsys/testsuite/ztest/include/zephyr/ztest_assert.h>

Assert that ptr is NULL.

Parameters
ptrPointer 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 </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/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 </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/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
bufBuffer to compare
expBuffer with expected contents
sizeSize 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 </home/runner/work/sdk-nrf/sdk-nrf/ncs/zephyr/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
aValue to compare
bValue to compare
...Optional message and variables to print if the assertion fails
