angularjs workout required parameters for any state - angularjs

Question

I an trying to list out all the URL's that exist in the stateprovider (angularjs 1.2.26).
given the example below, (very much cut down state list):
angular.module('app')
.config(function ($stateProvider) {
$stateProvider
.state('app.vendors', {
url: '/vendors',
templateUrl: 'app/vendor/list.html',
controller: 'Vendor.ListController as vm',
})
.state('app.vendor', {
url: '/vendor/{vendorId}',
templateUrl: 'app/vendor/details.html',
controller: 'Vendor.DetailsController as vm',
data: {
subnav: [
{ title: 'Details', icon: 'fa-align-left', state: 'app.vendor', permissions: 'get-vendor', exactStateOnly: true },
{ title: 'Sites', icon: 'fa-archive', state: 'app.vendor.sites', permissions: 'get-site' },
{ title: 'NCRs', icon: 'fa-copy', state: 'app.vendor.ncrs', permissions: 'get-vendor' }
],
requiredPermissions: ['get-vendor']
}
})
.state('app.vendor.sites', {
url: '/sites',
templateUrl: 'app/vendor/site/list.html',
controller: 'Vendor.Site.ListController as vm',
data: {
requiredPermissions: ['get-site']
}
})
.state('app.vendor.site', {
url: '/site/{siteId}',
templateUrl: 'app/vendor/site/details.html',
controller: 'Vendor.Site.DetailsController as vm',
data: {
requiredPermissions: ['get-site']
}
})
.state('app.vendor.ncrs', {
url: '/ncrs',
templateUrl: 'app/vendor/ncr/ncrList.html',
controller: 'Vendor.NCR.NCRListController as vm',
data: {
requiredPermissions: ['get-vendor']
}
});
});
to get to a particular vendor you would use state:
app.vendor({vendorId: 1})
to get to its site
app.vendor.site({vendorId: 1, siteId: 2})
if I pass in the $state object to a controller I can list all the states with state.get().
If I list them the urls only contain the last part (i.e. what is in the config, and relative to its parent). I can use $state.href('app.vendor.site') which will give me almost the whole url, but misses out the parameters. I am trying to find a way at runtime to know what or at least how many parameters it requires.
My goal is to try and create a basic smoke test for every page in our Angular app to ensure it loads something and doesn't through errors in the console. I dont want to have to manually maintain a list of urls with params. (all our params are int IDs so I can simply use "1" in the params to test the url).

The private portion of the state contains params and ownParams objects. You can use a decorator to access those internal variables. See my previous answer regarding exposing the entire internal state object using a decorator: UI-Router $state.$current wrapper for arbitary state
After decorating your state objects, use the $$state() function to retrieve the private portion. Then query the state for its params and generate the href.
angular.forEach($state.get(), function(state) {
var paramKeys = state.$$state().params.$$keys();
var fakeStateParams = {};
angular.forEach(paramKeys, function(key) { fakeStateParams[key] = key; });
console.log($state.href(state, fakeStateParams));
});
