# KUnity
|
||||||
|
|
||||||
|
KUnity configure the c unit test framework Unity (http://www.throwtheswitch.org/unity) so that it can use in kernel space. The test results will be "shown" by `printk`.
|
||||||
|
|
||||||
|
## Add KUnity to a kernel module
|
||||||
|
|
||||||
|
```Makefile
|
||||||
|
|
||||||
|
# add KUnity and Unity source files
|
||||||
|
module-objs += lib/KUnity/src/kunity.o
|
||||||
|
module-objs += lib/KUnity/lib/Unity/src/unity.o
|
||||||
|
|
||||||
|
# include KUnity and Unity header
|
||||||
|
ccflags-y += -I<lib_path>/KUnity/src
|
||||||
|
ccflags-y += -I<lib_path>/KUnity/lib/Unity/src
|
||||||
|
|
||||||
|
# set the unity config by header file flag, which is provided by KUnity
|
||||||
|
ccflags-y += -DUNITY_INCLUDE_CONFIG_H
|
||||||
|
```
|
||||||
|
|
||||||
|
## Write and Running test cases
|
||||||
|
|
||||||
|
Test can be written like Unity tests, but for the definition of the test function you have to use the ```KUNITY_TEST``` makro.
|
||||||
|
When a kunity test should run, its necessary to add the prefix ```kunity_test_``` to the test function name.
|
||||||
|
|
||||||
|
```c
|
||||||
|
#include <kunity.h>
|
||||||
|
// ... application includes
|
||||||
|
KUNITY_TEST(first_simple_test)
|
||||||
|
{
|
||||||
|
TEST_ASSERT_EQUAL(1, 0);
|
||||||
|
}
|
||||||
|
|
||||||
|
// add more tests
|
||||||
|
|
||||||
|
// run tests
|
||||||
|
int module_init(void) {
|
||||||
|
int result = 0;
|
||||||
|
UNITY_BEGIN();
|
||||||
|
RUN_TEST(kunity_test_first_simple_test);
|
||||||
|
// ... call the other tests
|
||||||
|
result = UNITY_END();
|
||||||
|
if ( < 1) {
|
||||||
|
// all tests was successful, startup module
|
||||||
|
// ...
|
||||||
|
}
|
||||||
|
|
||||||
|
return -result;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
For running tests it can also use the [KUnity-Test-Runner-Module](/kttd/KUnity-Test-Runner-Module)
