Stop ArrayOutOfBoundsException from halting program execution in Java

Question

Im am currently developing an automated "test" class (running several individual tests on other classes in the same package). The aim of the test file is to show whether each test either passed or failed. Some of the files being tested are not written correctly creating an ArrayOutOfBoundsException when running the test, that produces my test file to crash and not carry on until the end performing other tests. I am not in the position to modify code to fix the errors on the project being tested.

-> how to stop an exception from halting program execution in Java without creating any new classes

Thank for all your help, advice and sharing.

Answer 1

Best way to stop it happening: fix the code to perform appropriate checking.

If you can't fix the code which is actually failing, you could catch the exception explicitly at an "outer" level, log a warning and continue with the next file:

try
{
    operationWhichMightThrow();
}
catch (ArrayIndexOutOfBoundsException e)
{
    log.warning("Failed file " + filename, e);
    // Do whatever you need to continue to the next file.
}

Answer 2

Catch the exception and log it as a test failure.
