获取 npm 错误！ errno 199 when 运行带有黄瓜框架的量角器

Question

我是 JavaScript 和 Protractor 的新手，我将 Protractor 与 cucmber js 一起使用。我遇到的问题在代码下方：

Then(/^I verified all pages visible to logged in user$/, () => {

    var expVisibleNavPages = 'Home,Applications,Programs,Reports,Admin Tools,a';

    var NavLinks = element.all(by.css('ul.nav.navbar-nav')).get(0).all(by.css('a'));

    var len =0;

    NavLinks.then(function(result) {
            len = result.length;
            logger.info("TOTAL NAV LINKS ARE ARE:"+len);
        });


    var actVisibleNavPages = "";
    var iCt = 0;


    NavLinks.each(function (element) {

        element.getText().then(function(text){

        actVisibleNavPages += text+",";
        iCt++;

            if (len === iCt)
            {
                logger.info("ACTUAL PAGES:"+actVisibleNavPages);

                logger.info("EXPECTED PAGES:"+expVisibleNavPages);

                return expect(actVisibleNavPages).to.equal(expVisibleNavPages);
            }



        });


    });

我收到以下错误：

[2017-12-19T23:59:36.696] [INFO] default - TOTAL NAV LINKS ARE ARE:5 [2017-12-19T23:59:36.818] [INFO] default - ACTUAL PAGES:Home,Applications,Programs,Reports,Admin Tools, [2017-12-19T23:59:36.821] [INFO] default - EXPECTED PAGES:Home,Applications,Programs,Reports,Admin Tools,a [23:59:36] E/launcher - expected 'Home,Applications,Programs,Reports,Admin Tools,' to equal 'Home,Applications,Programs,Reports,Admin Tools,a' [23:59:36] E/launcher - AssertionError: expected 'Home,Applications,Programs,Reports,Admin Tools,' to equal 'Home,Applications,Programs,Reports,Admin Tools,a' at C:/HancockSoftwareAutomation/mdmf_automation_bdd/mdmf_e2e_gui_testing/stepDefinitions/navaigation_bar_steps.js:74:49 at elementArrayFinder_.then (C:\HancockSoftwareAutomation\mdmf_automation_bdd\mdmf_e2e_gui_testing\node_modules\protractor\built\element.js:804:32) at ManagedPromise.invokeCallback_ (C:\HancockSoftwareAutomation\mdmf_automation_bdd\mdmf_e2e_gui_testing\node_modules\selenium-webdriver\lib\promise.js:1376:14) at TaskQueue.execute_ (C:\HancockSoftwareAutomation\mdmf_automation_bdd\mdmf_e2e_gui_testing\node_modules\selenium-webdriver\lib\promise.js:3084:14) at TaskQueue.executeNext_ (C:\HancockSoftwareAutomation\mdmf_automation_bdd\mdmf_e2e_gui_testing\node_modules\selenium-webdriver\lib\promise.js:3067:27) at asyncRun (C:\HancockSoftwareAutomation\mdmf_automation_bdd\mdmf_e2e_gui_testing\node_modules\selenium-webdriver\lib\promise.js:2927:27) at C:\HancockSoftwareAutomation\mdmf_automation_bdd\mdmf_e2e_gui_testing\node_modules\selenium-webdriver\lib\promise.js:668:7 at at process._tickCallback (internal/process/next_tick.js:188:7) [23:59:36] E/launcher - Process exited with error code 199 npm ERR! code ELIFECYCLE npm ERR! errno 199

由于 npm errno 199，量角器进程正在终止并停止执行进一步的场景。

寻求帮助。

Answer 1

错误日志是不言自明的。您的脚本只找到 5 个 "NavLinks"，包括 Home、Applications、Programs、Reports、Admin Tools，而预期值为 6，另一个对象名为 "a"。这将导致断言错误。

Answer 2

我更新了如下代码，它起作用了：

Then(/^I verified all pages visible to logged in user$/, () => {

    var expVisibleNavPages = ["Home","Applications","Programs","Reports","Admin Tools","a"];

    let actVisibleNavPages =  element.all(by.css('ul.nav.navbar-nav')).get(0).all(by.css('a'));

     var promise = new Promise(function (resolve) {
        setTimeout(resolve, 200, actVisibleNavPages.getText());
    });


    return expect(promise).to.eventually.deep.equal(expVisibleNavPages);

});
