Unless there is a meteor-specific way to do this, you can implement the solution from [How to Unit Test Private Functions in JavaScript][1]

You will need to have a single global variable (something like `TestAPI`). Then add your functions to it inside of a closure so you can access them from anywhere.

Here's an example from the article:



<pre><code>var myModule = (function() {

 function foo() {
 // private function `foo` inside closure
 return "foo"
 }

 var api = {
 bar: function() {
 // public function `bar` returned from closure
 return "bar"
 }
 }

 /* test-code */
 api._foo = foo
 /* end-test-code */

 return api
}())</code></pre>

Someone might have something better, but that's a start.

In my server side file I have two functions defined for which I want to write test cases which are residing in a file in tests directory. 

~PRJ_DIR/server/file1.coffee

    
    calcSha1Hash = (params) ->
        .... logic...
    anotherFunc = () ->
        ..somelogic..
        x = calcSha1Hash(params)


~PRJ_DIR/tests/server/file1.coffee

    MochaWeb?.testOnly () ->
      describe.only("Hash generation.  ", () ->
        it(" calcSha1Hash returns Hash.", (dn) ->
          dataDict = {email: 'johndoe@gmail.com'}
          hash = calcSha1Hash (dataDict)
          chai.assert.isDefined(hash)
          dn()
        )
      )

How is it possible to call the server side func(calcSha1Hash) in my test case in Meteor
