In some cases the code runs into serious problems, which is normally causing the whole program to crash. Here are some examples common exceptions the STC is capable to handle:

  • Access to a memory area which is invalid
  • division by zero
  • access to an invalid array element.

If one of the supported exceptions is thrown, AxUint will show the current test as failed, instead of crashing the whole program.
