title: How to import functions from different files in robot framework?
body: <p>I am writing automation test scripts using Robot Framework &amp; Selenium2Library for testing our web application ( <strong>in .txt format</strong> ).  </p>
  
  <p>Is there any option in robot framework to import functions / modules written in another files ?  </p>
  
  <p><strong>For example</strong> :</p>
  
  <p>I have written almost 300 test cases for testing our web application. All test cases contains a common function for login validation . </p>
  
  <p>In case if I have to make a small change in this particular ( logIn ) function, I have go through each test case &amp; make necessary changes . </p>
  
  <p>It's really a time consuming process . </p>
  
  <p>So, I just want to know , Is there any option in robot framework to write test cases in a modular way ?  </p>
  
  <p>Just like , if I write a ' login.txt ' function for login validation - Is there any option available in robot framework to import this particular function to any other test cases ?     </p>
  
  <p>Is there any keyword like 'Import Function' / 'Import Module' available for this particular scenario ? </p>
