Incorrect question. Then ask how to stop stuttering. As long as you treat it as a test, you will continue to fail, nothing will change. Be in the topic of your dialog without hindsight, then you will say your name when you need to. If you have to introduce yourself, make your greeting a little longer in your head. For example, instead of just "first name/surname" tune in to a small sentence, example: "my name is <...>, what about you?" or "I <...>, wanted to ask you about...". When you intentionally set a more difficult task in advance, it will be easier for you to introduce yourself because your brain won't perceive it as something hard if you tune into it. And don't forget the first point. This should NOT be your test, any stutterer, even one who has acquired near-perfect fluency, will fail when it comes to testing his speech.
