Best way to create a multi-step validation process

Question

I am writing a multi step validation process and I was wondering what is the best method to have it operate on the value.  What I have:
As a custom validation script, in that order:
1- Calls a function that looks if the value is part of a particular array
2- Calls a function that regroup some tests
     2a- function test1()
     2b- function test2()
     2c- function test3()
     2d- function test4()
What I have now is every test ends as 'event.rc = false' when they fail which is what I need but I also need to stop the entire validation process.  As an example, if the value fails test2() and gets a "you have failed test 2" alert, I don't want to call test3() and test4() since it is already decided that it failed one of the tests.  I could return a boolean that triggers (or not) the next test() but isn't there a simple way to just say
event.rc = false;
"STOP EVERYTHING";
I have the assumption that break; will only stop the test() but still move on to the next test().  Maybe I can return break; so it will be called from the 'master function'?   Is that even possible?

Answer 1

Create another function and call it from the validation script, something like:
function validate_field() {
    // Call the first validation routine
    test0();
    // Abort if first validation fails
    if (!event.rc) return;
    // Call the second validation routine
    test1();
    // Abort if second validation fails
    if (!event.rc) return;
    // Repeat for any other tests
