我使用jasmine-rails gem运行Rails 3.2.8。以下是我的Gemfile中描述茉莉花设置的行:
jasmine (1.2.1)
jasmine-core (>= 1.2.0)
rack (~> 1.0)
rspec (>= 1.3.1)
selenium-webdriver (>= 0.1.3)
jasmine-core (1.2.0)
jasmine-headless-webkit (0.8.4)
coffee-script
jasmine-core (~> 1.1)
multi_json
rainbow
sprockets (~> 2)
jasmine-rails (0.1.0)
jasmine
jasmine-headless-webkit
rails (>= 3.1.0)
我也在使用jasmine-jquery扩展程序。这组函数提供了我在测试中使用的toHaveText方法。我已将jasmine-jquery扩展文件保存到spec / javascripts / helpers目录中。
名为UserInvitationsSpec.js的测试文件直接位于spec / javascripts目录中,其中包含以下内容:
describe ("my basic jasmine jquery test", function(){
beforeEach(function(){
$('body').append('<a id="test_link" href="somewhere.html">My test link</a>');
});
afterEach(function(){
$('a#test_link').remove();
});
it ("does some basic jQuery thing", function () {
$('a#test_link').click();
expect($("a#test_link")).toHaveText('My test link is now longer');
});
it ("does some the same basic jQuery thing with a different trigger type", function () {
$('a#test_link').trigger('click');
expect($("a#test_link")).toHaveText('My test link is now longer');
});
});
describe ('subtraction', function(){
var a = 1;
var b = 2;
it("returns the correct answer", function(){
expect(subtraction(a,b)).toBe(-1);
});
});
正如您所看到的,我已经包含了一个基本的javascript测试,以表明非jQuery测试正在按预期工作。
我的javascript文件core.js位于app / assets / javascripts目录中,有以下内容:
function subtraction(a,b){
return a - b;
}
jQuery (function($) {
$("a#test_link").click(changeTheTextOfTheLink)
function changeTheTextOfTheLink(e) {
e.preventDefault()
$("a#test_link").append(' is now longer');
}
});
当我通过终端运行'bundle exec jasmine-headless-webkit'时,这是输出:
FF.
FAIL: 3 tests, 2 failures, 0.013 secs.
my basic jasmine jquery test does some basic jQuery thing. (/Users/rebekah/OPSWAT/opswat_cwm/spec/javascripts/UserInvitationsSpec.js:11)
Expected '<a id="test_link" href="somewhere.html">My test link</a>' to have text 'My test link is now longer'. (line ~13)
expect($("a#test_link")).toHaveText('My test link is now longer');

expect($("a#test_link")).toHaveText('My test link is now longer');
我的application.js文件位于同一个app / assets / javascripts目录中,有这样的内容:
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require vendor
//= require_tree .
我在spec / javascripts / support dir中的jasmine.yml文件包含以下内容:
src_files:
- "application.{js,coffee}"
stylesheets:
helpers:
- "helpers/**/*.{js,coffee}"
spec_files:
- "**/*[Ss]pec.{js,coffee}"
src_dir: "app/assets/javascripts"
spec_dir: spec/javascripts
asset_paths:
- "vendor/assets/javascripts"
知道为什么在应用程序中正常运行的jQuery函数没有在测试环境中执行?
非常感谢!

答案 0 :(得分:1)
jQuery的document.ready
事件(jQuery(function ($) { … });
)在Jasmine的beforeEach
之前运行,这意味着您正在尝试将点击处理程序绑定到尚未添加到文档的链接爱好。
这是一个简化的例子:
// application.js
jQuery(function ($) {
console.log("In document.ready");
});
// test_spec.js
describe("the order of things", function () {
beforeEach(function () {
console.log("In beforeEach");
});
it("should run some tests", function () {
console.log("In test");
});
});
这给出了这个输出:
$ bundle exec jasmine-headless-webkit
"In document.ready"
Running Jasmine specs...
"In before each"
"In test"
.
PASS: 1 test, 0 failures, 0.004 secs.
不幸的是,我在Jasmine Headless Webkit(这是jasmine-rails在幕后使用的)文档中找不到有关使用自定义HTML模板的任何内容。
