E2E测试 - WebdriverJS，Selenium和Jasmine [英] E2E Testing - WebdriverJS, Selenium and Jasmine

问题描述

好的，所以我按照了几个略有不同的例子，你可以在下面的评论代码中看到。他们都声称工作，但我不能这样做。

OK so I have followed several slightly differing examples, as you can see in my commented code below. They all claim to work, but I cannot get it to do so.

我正在使用;
- selenium-webdriver
- jasmine-node-reporter-fix （ jasmine-node 错误）

I'm using; - selenium-webdriver - jasmine-node-reporter-fix (jasmine-node errors)

所以这是一个非常简单的异步测试，打开Goog​​le并搜索，然后获取页面标题。

So its quite a simple asynchronous test, opening Google and searching, then getting the page title.

问题;
返回的网页标题是Google主页，而不是搜索结果页。 （浏览器最终显示在搜索结果页面上。）

Problem; The page title returned is the Google homepage and not the search results page. (Browser ends up on the search results page).

代码

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.firefox()).
    build();

jasmine.DEFAULT_TIMEOUT_INTERVAL = 9999999;

describe('basic test', function () {

    it('should be on correct page', function (done) {
        //driver.get('http://www.wingify.com');
        //driver.getTitle().then(function (title) {
        //  expect(title).toBe('Wingify');
        //  // Jasmine waits for the done callback to be called before proceeding to next specification.
        //  done();
        //});


        driver.get("http://www.google.com");
        driver.findElement(webdriver.By.name("q")).sendKeys("webdriver");
        driver.findElement(webdriver.By.name("btnG")).click();
        //driver.getTitle().then(function (title) {
        //  console.log(title);
        //  console.log(expect);
        //  expect(title).toBe('webdriver - Google Search');
        //  done();
        //});
        driver.wait(function () {
            driver.getTitle().then(function (title) {
                expect(title).toBe('webdriver - Google Search');
                done();
            });
        }, 5000);

    });
});

结果

Failures:

  1) basic test should be on correct page
   Message:
     Expected 'Google' to be 'webdriver - Google Search'.
   Stacktrace:
     Error: Expected 'Google' to be 'webdriver - Google Search'.

Finished in 4.281 seconds
1 test, 1 assertion, 1 failure, 0 skipped

所以有些人说我需要延长茉莉花超时，这没什么区别。

So some people have said I need the jasmine timeout extended, this makes no difference.

其他人说你需要Jasmine done（）方法 - 没有这个测试没有完成。

Others saying you need the Jasmine done() method - without this the test doesn't complete.

我不明白为什么等待不等！ - 无论超时提供什么，结果都会立即返回。

I cannot see why the wait doesn't wait! - the result is returned immediately whatever the timeout provided.

推荐答案

所以，上面的问题是我无法获得Jasmine使用driver.wait在执行断言之前等待页面加载。

So, the problem with the above was that I could not get Jasmine to wait for the page load before doing the assertion, using driver.wait.

Jasmine在driver.wait返回之前完成。

Jasmine was completing before driver.wait returned.

相反，我使用了Jasmine的waitsFor（）方法。

Instead I used Jasmine's waitsFor() method.

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

describe('basic test', function () {

    it('should be on correct page', function () {
        var match = 'webdriver - Google Search',
            title = '';

        driver.get("http://www.google.com");
        driver.findElement(webdriver.By.name("q")).sendKeys("webdriver");
        driver.findElement(webdriver.By.name("btnG")).click();

        // wait for page title, we know we are there
        waitsFor(function () {
            driver.getTitle().then(function (_title) {
                title = _title;
            });
            return title === match;
        }, 'Test page title, so we know page is loaded', 6000);

        // test title is correct
        runs(function () {
            expect(title).toEqual(match);
        });
    });
});
