$rootScope.Scope.$eval()

$eval([expression], [locals]);

Executes the expression on the current scope and returns the result. Any exceptions in the expression are propagated (uncaught). This is useful when evaluating Angular expressions.

var scope = ng.$rootScope.Scope();
scope.a = 1;
scope.b = 2;

expect(scope.$eval('a+b')).toEqual(3);
expect(scope.$eval(function(scope){ return scope.a + scope.b; })).toEqual(3);
