zexpect_between_inclusive

#define zexpect_between_inclusive	(		a,
			lower,
			upper,
			...
	)

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

Value:

        zexpect(((a) >= (lower)) && ((a) <= (upper)),                                              \
                #a " not between " #lower " and " #upper " inclusive", ##__VA_ARGS__)

Expect that a is greater than or equal to l and less than or equal to u, otherwise mark test as failed but continue its execution.

Parameters

a	Value to compare
lower	Lower limit
upper	Upper limit
...	Optional message and variables to print if the expectation fails

zexpect_equal

#define zexpect_equal	(		a,
			b,
			...
	)		zexpect((a) == (b), #a " not equal to " #b, ##__VA_ARGS__)

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

Expect that a equals b, otherwise mark test as failed but continue its execution. expectation fails, the test will be marked as "skipped".

Parameters

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

zexpect_equal_ptr

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

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

Expect that a equals b, otherwise mark test as failed but continue its execution.

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 expectation fails

zexpect_false

#define zexpect_false	(		cond,
			...
	)		zexpect(!(cond), #cond " is true", ##__VA_ARGS__)

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

Expect that cond is false, otherwise mark test as failed but continue its execution.

Parameters

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

zexpect_is_null

#define zexpect_is_null	(		ptr,
			...
	)		zexpect((ptr) == NULL, #ptr " is not NULL", ##__VA_ARGS__)

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

Expect that ptr is NULL, otherwise mark test as failed but continue its execution.

Parameters

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

zexpect_mem_equal

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

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

Expect that 2 memory buffers have the same contents, otherwise mark test as failed but continue its execution.

Parameters

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

zexpect_not_equal

#define zexpect_not_equal	(		a,
			b,
			...
	)		zexpect((a) != (b), #a " equal to " #b, ##__VA_ARGS__)

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

Expect that a does not equal b, otherwise mark test as failed but continue its execution.

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 expectation fails

zexpect_not_null

#define zexpect_not_null	(		ptr,
			...
	)		zexpect((ptr) != NULL, #ptr " is NULL", ##__VA_ARGS__)

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

Expect that ptr is not NULL, otherwise mark test as failed but continue its execution.

Parameters

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

zexpect_ok

#define zexpect_ok	(		cond,
			...
	)		zexpect(!(cond), #cond " is non-zero", ##__VA_ARGS__)

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

Expect that cond is 0 (success), otherwise mark test as failed but continue its execution.

Parameters

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

zexpect_true

#define zexpect_true	(		cond,
			...
	)		zexpect(cond, #cond " is false", ##__VA_ARGS__)

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

Expect that cond is true, otherwise mark test as failed but continue its execution.

Parameters

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

zexpect_within

#define zexpect_within	(		a,
			b,
			delta,
			...
	)

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

Value:

        zexpect(((a) >= ((b) - (delta))) && ((a) <= ((b) + (delta))),                              \
                #a " not within " #b " +/- " #delta, ##__VA_ARGS__)

Expect that a is within b with delta d, otherwise mark test as failed but continue its execution.

Parameters
