_ReturnArrayThruPtr not returning values but _ReturnThruPtr works fine

[Christian Cortes]

Hello everyone, 

I do not understand and i might be doing something wrong here so i will give some detail.

I am mocking a built in 12c_read function (dev, ADDR, read_buff, sizeof(readbuff))

this function works with both given single uint8_t val and an array of uint8_t but cannot get it to work while testing. 

the working example using a single uint8_t val

struct device *i2c_dev = GET(DEV);

uint8_t ADDR = 0x19;

uint8_t val = 0xf;

i2c_read_ExpectAndReturn(dev, ADDR, NULL, sizeof(val));

i2c_read_IgnoreArg_read_buffer(); /// this is that name of the 3rd arg in read function

i2c_read_ReturnThruPtr_read_buffer(&val);

in the situation above, it woks and i am able to go through all branches from the function that i am testing. 

but if i change this to be used as an array It returns all zeros and i cannot test any of the 

logic that checks for non-zero data. 

uint8_t val[] = {0x2, 0x3};

uint8_t size = 2;

i2c_read_ExpectAndReturn(dev, ADDR, NULL, sizeof(val));

i2c_read_IgnoreArg_read_buffer(); /// this is that name of the 3rd arg in read function

i2c_read_ReturnArrayThruPtr_read_buffer(&val, size);

am i not using ReturnArray... correctly? 

thanks.

You're passing a pointer to the array instead of the array pointer on that last line. I'm pretty sure you mean to use this:

i2c_read_ReturnArrayThruPtr_read_buffer(val, size); //notice no & before val
