Detailed Description

This module provides assumptions when using Ztest.

Macro Definition Documentation

zassume_between_inclusive

#define zassume_between_inclusive	(		a,
			l,
			u,
			...
	)

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

Value:

        zassume(((a) >= (l)) && ((a) <= (u)), #a " not between " #l " and " #u " inclusive",       \
                ##__VA_ARGS__)

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

If the assumption fails, the test will be marked as "skipped".

Parameters

a	Value to compare
l	Lower limit
u	Upper limit
...	Optional message and variables to print if the assumption fails

zassume_equal

#define zassume_equal	(		a,
			b,
			...
	)		zassume((a) == (b), #a " not equal to " #b, ##__VA_ARGS__)

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

Assume that a equals b.

a and b won't be converted and will be compared directly. If the assumption 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 assumption fails

zassume_equal_ptr

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

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

Assume that a equals b.

a and b will be converted to void * before comparing. If the assumption 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 assumption fails

zassume_false

#define zassume_false	(		cond,
			...
	)		zassume(!(cond), #cond " is true", ##__VA_ARGS__)

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

Assume that cond is false.

If the assumption fails, the test will be marked as "skipped".

Parameters

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

zassume_is_null

#define zassume_is_null	(		ptr,
			...
	)		zassume((ptr) == NULL, #ptr " is not NULL", ##__VA_ARGS__)

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

Assume that ptr is NULL.

If the assumption fails, the test will be marked as "skipped".

Parameters

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

zassume_mem_equal

#define zassume_mem_equal

(

...

)

zassume_mem_equal__(__VA_ARGS__)

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

Assume that 2 memory buffers have the same contents.

This macro calls the final memory comparison assumption 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 zassume_mem_equal__ for real arguments accepted.

zassume_mem_equal__

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

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

Internal assume that 2 memory buffers have the same contents.

If the assumption fails, the test will be marked as "skipped".

Note

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

Parameters

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

zassume_not_equal

#define zassume_not_equal	(		a,
			b,
			...
	)		zassume((a) != (b), #a " equal to " #b, ##__VA_ARGS__)

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

Assume that a does not equal b.

a and b won't be converted and will be compared directly. If the assumption 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 assumption fails

zassume_not_null

#define zassume_not_null	(		ptr,
			...
	)		zassume((ptr) != NULL, #ptr " is NULL", ##__VA_ARGS__)

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

Assume that ptr is not NULL.

If the assumption fails, the test will be marked as "skipped".

Parameters

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

zassume_not_ok

#define zassume_not_ok	(		cond,
			...
	)		zassume(!!(cond), #cond " is zero", ##__VA_ARGS__)

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

Assume that cond is not 0 (failure)

If the assumption fails, the test will be marked as "skipped".

Parameters

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

zassume_ok

#define zassume_ok	(		cond,
			...
	)		zassume(!(cond), #cond " is non-zero", ##__VA_ARGS__)

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

Assume that cond is 0 (success)

If the assumption fails, the test will be marked as "skipped".

Parameters

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

zassume_str_equal

	)		zassume(strcmp(s1, s2) == 0, #s1 " not equal to " #s2, ##__VA_ARGS__)

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

Assumes that 2 strings have the same contents.

Parameters

s1	The first string
s2	The second string
...	Optional message and variables to print if the expectation fails

zassume_true

#define zassume_true	(		cond,
			...
	)		zassume(cond, #cond " is false", ##__VA_ARGS__)

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

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

Value:

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

Assume that a is within b with delta d.

If the assumption fails, the test will be marked as "skipped".
