##Documentation(How to use the library):

Lib -- Library itself [global object]

Lib.preCallTest(mediaDeviceTest, connectivityTest, displayOutputOnScreen, callback);

[params]:

mediaDeviceTest [boolean] -- whether to perform mediaDevices test

connectivityTest [boolean] -- whether to perform connectivity test

displayOutputOnScreen [string] -- whether to display the result on the screen[ DOM element Id of the text area ]

callback [function] -- Function to execute when the test is finished.

             Example:  
             
             Lib.preCallTest(mediaDevices, connectivity, messageBoxId, function (testResult) {
                  console.log(testResult);
             });
             
            Sample Output: 
            
            {
