How to skip test items and go to specified test item if some condition is satisfied ?

Yep, it's possible.  But you need to do configurations, you need error checking within the tests, etc.  This item was addressed sometime back.  Here's a bit of code I wrote to demonstrate:

function TestA(isError) {
    try {
        if (isError) {
            throw new Error('Got an error in Test A');
        } 
        else {
            Log.Message('No error in Test A');
            TestB();  
        }
    }
    catch (e) {
        Log.Error('rasied an error: ' + e.message, e.stack);
    }
}

function TestB() {
    Log.Message('Ran test B');
}

function TestC(isError) {
    try {
        if (isError) {
            throw new Error('Got an error in Test C');
        } 
        else {
            Log.Message('No error in Test C'); 
            TestD(); 
        }
    }
    catch (e) {
        Log.Error('rasied an error: ' + e.message, e.stack);
    }
}

function TestD() {
    Log.Message('Ran test D');
}

function RunAll() {
    TestA(true);
    TestC(false);
    
}

I then configured my test items like so...

This is just one way.  There are other ways with writing more complicated code, but, essentially, you'll want to do something similar.
