AngularJS - Test if a string matches a route

Is there a way in angular, when given the following route

.when('/customer/:customerId', {
    templateUrl: 'views/summary.tpl.html',
    controller: 'SummaryController'
})

to be able to test if a string matches that route?

For example with the string

'/customer/3'

is there a function in angular that I can call to determine if the route matches a route or not?
