【问题标题】:Jasmine never executes it, when running in PhantomJSJasmine 在 PhantomJS 中运行时从不执行它
【发布时间】:2014-02-14 05:56:49
【问题描述】:

我正在尝试在 PhantomJS 中运行 Jasmine。经过一番努力,我决定:

    page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/jasmine.js");
    page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/jasmine-html.js");
    page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/boot.js");
    page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/console.js");
    var result = page.evaluate(function (done) {
        var ConsoleReporter = jasmineRequire.ConsoleReporter();
        var options = {
            timer: new jasmine.Timer,
            print: function () {
                console.log.apply(console, arguments)
            }
        };
        consoleReporter = new ConsoleReporter(options);
        jasmine.getEnv().addReporter(consoleReporter);

        describe("test1", function () {
            console.log("in test 1");
            it("should do something", function () {
                console.log("NEVER GETS HERE"); // <-- never gets there
            });
        });
    });

代码一直执行到 it() 但回调从不执行:|

[编辑] 我正在尝试使用带有茉莉花的幻影进行端到端测试。我已经有一个应用服务器,并且正在使用 Karma 进行单元测试。所以我认为 testRunner.html 不会有帮助。 PhantomJS 应该登录到我的应用程序并执行一些操作,我将使用 Jasmine 进行测试。

    【解决方案1】:

    通过愚蠢的运气蛮力方法得到它。我从未找到有用的文档,但 this 提供了一点帮助

    我的文件是这样的:

    testrunner.js

    var system = require("system");
    var page = require("webpage").create();
    
    var loginUrl = system.args[1];
    
    page.onConsoleMessage = function (msg) {
        console.log("FROM PAGE: " + msg);
    };
    
    page.onError = function (err) {
        console.log("ERR FROM PAGE: " + JSON.stringify(err));
    }
    
    var loggedIn = false;
    function onLogin_atHomePage() {
        if (loggedIn)
            return; // dont run twice if a developer is programatically logging in 
            page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/jasmine.js");
            page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/boot.js");
            page.injectJs("/jasmine-standalone-2.0.0/lib/jasmine-2.0.0/console.js");
            var result = page.evaluate(function (done) {
                var ConsoleReporter = jasmineRequire.ConsoleReporter();
                var options = {
                    timer: new jasmine.Timer,
                    print: function () {
                        console.log.apply(console, arguments)
                    }
                };
                consoleReporter = new ConsoleReporter(options); // initialize ConsoleReporter
                jasmine.getEnv().addReporter(consoleReporter); //add reporter to execution environment
    
                describe("test1", function () {
                    console.log("in test 1");
                    it("should do something", function () {
                        console.log("NEV");
                    });
                });
    
                jasmine.getEnv().execute();
            });
    }
    
    page.open(loginUrl, function () {
        console.log("LOGGING IN...");
        page.onLoadFinished = onLogin_atHomePage;
        page.evaluate(function () {
            $(document).ready(function () {
                var $u = $("#login_id");
                var $p = $("[name='password']");
                $u.val("me");
                $p.val("666");
                submitForm();
            });
        });
    });
    

    boot.js

    /**
     Starting with version 2.0, this file "boots" Jasmine, performing all of the necessary initialization before executing the loaded environment and all of a project's specs. This file should be loaded after `jasmine.js`, but before any project source files or spec files are loaded. Thus this file can also be used to customize Jasmine for a project.
    
     If a project is using Jasmine via the standalone distribution, this file can be customized directly. If a project is using Jasmine via the [Ruby gem][jasmine-gem], this file can be copied into the support directory via `jasmine copy_boot_js`. Other environments (e.g., Python) will have different mechanisms.
    
     The location of `boot.js` can be specified and/or overridden in `jasmine.yml`.
