What would happen if setTestMode is used in live environment?

I just want an understanding of what setTestMode would do when used in a live environment?

Would it allow me to test using the test credit card numbers? Would all transactions fail automatically if setTestMode is true? etc...

    If setTestMode is true and you don't specify a "test" store ID and API token, all transactions will fail because the test environment will not recognize the production (live) store ID and API token.
