Consider update the pin signal state inside setReactorEnableStatus() function. So there is no need to keep updating the pin signal state after each call to function setReactorEnableStatus().
Set result to pass before running the for loop. Remove failure count and set self test result to fail in place where we increase failure count. We can get rid of this if else.
Your solution requires a code change to be made and the entire denali application to have to be rebuilt every time a treatment parameter needs to be adjusted by systems. This will not serve the needs of the system team. To fulfill their needs it was requested at the time to put the values in a file. You and I agreed at the time that the treatment parameter ranges should be read from a file. These two treatment parameter ranges are being read from QML which contradicts our agreed-upon decision to have them read from a file.
