title: mocking SFTP using MUNIT
body: <p>I have already seen the same question <a href="https://stackoverflow.com/questions/23222864/how-to-fake-sftp-server-on-mule-unit-test">here</a>, but the links provided in the answer are not working now. so seriously needed a solution for this issue.</p>
  
  <p>I have an SFTP setup in my mule flow along with a Database. I need to mock the SFTP and test my mule flow using MUNIT. Can you please share some steps on how to proceed for this scenario?</p>
