uninitvar false positive

[Pascal Roobrouck]

as I am new to cppcheck I am not sure this is a false positive or an error in my code...

my unit test is

void test_sensorCollection_initalize() {
    sensorCollection aCollection;
    TEST_ASSERT_EQUAL_UINT32(0, aCollection.actualNumberOfSensors);
}

cppcheck complains

[high:error] Uninitialized variable: aCollection.actualNumberOfSensors [uninitvar]

but in the sensorCollection class there is a straightforward braced initialization of this memberVariable

uint32_t actualNumberOfSensors{0};

using cppcheck from within PlatformIO, and it is version 2.7

Can you provide some little example code that reproduces the error?

It sounds like a false positive to me.

I can't reproduce with this code:

class sensorCollection {
    int actualNumberOfSensors{0};
};

void test_sensorCollection_initalize() {
    sensorCollection aCollection;
    if (0 == aCollection.actualNumberOfSensors){}
}

There might be some little detail in your code that confuses Cppcheck.. personally I would suggest that you repeat this procedure below until you have a small code example:

• remove/simplify some piece of code
• run cppcheck
• if error is not written by cppcheck , undo step 1
• repeat
