如何在Angular 1.5组件中对具有不同名称的绑定进行单元测试？

Question

我有以下组件:

angular.module('foo')
    .component('searchInput', {
        bindings: {
            text: "<query"
        },
        templateUrl: 'components/searchInput/searchInput.html',
        controller: 'SearchInputCtrl'
    });

以下通过:

expect(component.text).toBe('bar');

我必须使用以下代码:

    var component = $componentController('searchInput',
        {$scope: {}},
        {
            text: 'bar'
        }
    );

但是,我想测试绑定到'text'的值来自'query'.这不起作用:

    var component = $componentController('searchInput',
        {$scope: {}},
        {
            query: 'bar'
        }
    );

您可以通过编译组件来测试此类事物.例如

inject(function($compile, $rootScope) {
    var parentScope = $rootScope.$new();
    parentScope.myVar = 'test';

    var element = angular.element('<search-input query="myVar"></search-input>');

    var compiledElement = $compile(element)(parentScope);
    parentScope.$digest();

    var scope = compiledElement.isolateScope();

    expect(scope.$ctrl.text).toBe('test');
});
