我正在使用Smart Table并尝试使用Karma设置一些测试。我反复收到错误Error: [$compile:ctreq] Controller 'stTable', required by directive 'removePag', can't be found!
。实际使用该指令时,我没有收到任何错误。在我看来,Karma应该为tools
模块提供智能表,这是我在规范中提到的,但没有骰子。我如何确保stTable
可以在测试中使用removePag
?
在tools.js中(包括expose
,因为我怀疑它可能会涉及,因为它是一个链接到顶级st-table
的指令):
angular.module('tools', ['smart-table'] );
angular
.module('freeTools')
.directive('expose', exposeTableState)
.directive('removePag', removePag)
function exposeTableState(){
return {
require:'stTable',
link:function(scope, element, attr, ctrl){
scope.smartTableState=ctrl.tableState();
}
};
}
function removePag() {
return {
restrict: 'E',
require: '^stTable',
template: '<a href="">View as a single page</a>',
link: function(scope, element, attrs, ctrl) {
return element.bind('click', function () {
return scope.$apply(function () {
var tableState;
tableState = ctrl.tableState();
tableState.pagination.number = tableState.pagination.totalItemCount;
return ctrl.pipe();
});
});
}
};
}
在toolsSpec.js中:
describe('tools', function () {
var $compile,
$rootScope;
beforeEach(module('freeTools'));
beforeEach(inject(function(_$compile_, _$rootScope_){
$compile = _$compile_;
$rootScope = _$rootScope_;
}));
it('Replaces the element with the appropriate content', function() {
var element = $compile("<remove-pag></remove-pag>")($rootScope);
$rootScope.$digest();
expect(element.html()).toContain("View as a single page");
});
}
在Karma.conf中:
module.exports = function(config){
config.set({
basePath : '../../',
files : [
'bower_components/jquery/dist/jquery.js',
'bower_components/angular/angular.js',
'bower_components/angular-smart-table/dist/smart-table.js',
'bower_components/angular-mocks/angular-mocks.js',
'assets/scripts/*.js',
'assets/test/*.js'
],
autoWatch : true,
frameworks: ['jasmine-ajax', 'jasmine'],
browsers : ['Chrome'],
plugins : [
'karma-chrome-launcher',
'karma-firefox-launcher',
'karma-jasmine-ajax',
'karma-jasmine',
],
});
};
简化的html:
<section ng-app="tools">
<table st-table="data" st-safe-src="safe" expose>
<div st-pagination>
<remove-pag></remove-pag>
我意识到问题与Unit testing an AngularJS (Smart Table) directive非常相似。模仿智能表测试自己的控制器的方式也没有,正如那里所建议的那样。无论如何,模块源代码中的stTable
似乎是指令,而不是控制器。
我还尝试在测试中使用st-table包装元素,例如$compile("<table st-table><remove-pag>...
,但错误相同。
我已经查看了Controller Required By Directive Can't Be Found等问题,但我已经有了共享父级tools
。
答案 0 :(得分:0)
问题显然是父必须被嘲笑。 H / t到Unit testing AngularJS child directive that requires parent directive有关模拟的指导。
it('Replaces the element with the appropriate content', function() {
// This can be anything, even an empty object.
var stTableControllerMock = {
idk: function () {
return 'something';
}
};
// Create element with dummy parent
var element = angular.element('<fake-parent><remove-pag></remove-pag></fake-parent>');
// '$' + {nameOfMissingController} + 'Controller' = '$stTableController'
element.data('$stTableController', stTableControllerMock);
// Compile, find the element we're testing, and digest
$compile(element)($rootScope.$new());
element = element.find('remove-pag');
$rootScope.$digest();
// Test
expect(element.html()).toContain("View as a single page");
});
