title: How do you test code written against AWS API
body: <p>I'm writing an application in Java that will upload a file up to AWS S3. The file will be given to the application in an argument, not hardcoded. I'd like to write tests to ensure that the file actually gets uploaded to S3. The test will be written before the code for TDD. (I have actually already written the code, but I'd like to ingrain TDD practices into all of my work as a habit)</p>
  
  <p>How exactly would I go about doing this? I will be using JUnit as that's what I'm most familiar with.</p>
  
  <p>Thanks in advance for any help.</p>
