Difference between angular.copy() and assignment (=).

$cope.context = 'some text';

$scope.master = context;

Thus in the later case, if you we're to change something in $scope.master you would also change context.

But in $scope.master = angular.copy($scope.context);

angular.copy() performs a deep copy of the argument - essentially creating a new object - whereas using the assignment operator = just assigns reference's.

Methods defined as TestMethod do not support Web service callouts Stack Trace: null

This error occurs because webService callouts is not allowed in Test class.

To bypass callouts add HttpcalloutMock class.

Here is Sample test class with mock class to bypass webservice Callout.

********************** Test Class ***************************

@isTest
private class Test_class {

private class RestMock implements HttpCalloutMock {

public HTTPResponse respond(HTTPRequest req) {
String fullJson = 'your Json Response';

HTTPResponse res = new HTTPResponse();
res.setHeader('Content-Type', 'text/json');
res.setBody(fullJson);
res.setStatusCode(200);
return res;
}
}
  static testMethod void service_call() {

  Test.setMock(HttpCalloutMock.class, new RestMock());
Test.startTest();

//your webserive call code

Test.StopTest();

}
}

Mock class will take care webservice callouts.
