您好，我是 webdriverio 自动化的新手，在练习 webdriverio 时，我发现了一个奇怪的行为。
这是我的测试代码
const internetPage = require("../pages/InternetPage"); //Importing InternetPage in javascript
describe("Handling checkboxes", function(){
it("Check page url ", function(){
browser.url("/");
expect(browser.getUrl() === ("https://the-internet.herokuapp.com/"));
});
it("Should click on checkbox", function(){
// browser.url("/");
internetPage.clickOnLink(6);
// browser.pause(1000);
internetPage.h3Header.waitForDisplayed();
internetPage.clickOnCheckBox(1);
expect(internetPage.getCheckboxElement(1).isSelected() === true);
/**
*
* FYI : FOUND SOME ISSUE THAT .equal or .equals () method doesnot work instead use === to compare or check whether the actual value is equals to the expected value
*/
browser.pause(5000);
});
it("check checkbox page header", function(){
internetPage.clickOnLink(6);
internetPage.h3Header.waitForDisplayed();
const text = internetPage.h3Header.getText();
expect(text === "Checkboxes");
});
});
当我编写这段代码时，我的测试成功通过， 但是如果我使用下面给定的代码
describe("Handling checkboxes", function(){
it("Check page url ", function(){
browser.url("/");
expect(browser.getUrl().equals("https://the-internet.herokuapp.com/"));
});
it("Should click on checkbox", function(){
// browser.url("/");
internetPage.clickOnLink(6);
// browser.pause(1000);
internetPage.h3Header.waitForDisplayed();
internetPage.clickOnCheckBox(1);
expect(internetPage.getCheckboxElement(1).isSelected().equals(true));
/**
*
* FYI : FOUND SOME ISSUE THAT .equal or .equals () method doesnot work instead use === to compare or check whether the actual value is equals to the expected value
*/
browser.pause(5000);
});
it("check checkbox page header", function(){
internetPage.clickOnLink(6);
internetPage.h3Header.waitForDisplayed();
const text = internetPage.h3Header.getText();
expect(text.equals("Checkboxes"));
});
});
然后我的测试功能正常工作，即它启动浏览器，单击复选框并验证该复选框是否已选中，但显示给定的错误。
我的页面对象文件名 InternetPage.js 文件如下
class InternetPage{
get h3Header(){
return $('h3');
}
getLinkElement(index){
return $(`ul > li:nth-child(${index}) a`);
}
clickOnLink(index){
this.getLinkElement(index).waitForDisplayed();
this.getLinkElement(index).click();
}
getCheckboxElement(index){
return $(`form#checkboxes > input:nth-child(${index})`);
}
clickOnCheckBox(index){
this.getCheckboxElement(index).waitForDisplayed();
this.getCheckboxElement(index).click();
}
} module.exports = new InternetPage();
我还附上了我的 package.json 文件

//
// ====================
// Runner Configuration
// ====================
//
//
// ==================
// Specify Test Files
// ==================
// Define which test specs should run. The pattern is relative to the directory
// from which `wdio` was called.
//
// The specs are defined as an array of spec files (optionally using wildcards
// that will be expanded). The test for each spec file will be run in a separate
// worker process. In order to have a group of spec files run in the same worker
// process simply enclose them in an array within the specs array.
//
// If you are calling `wdio` from an NPM script (see https://docs.npmjs.com/cli/run-script),
// then the current working directory is where your `package.json` resides, so `wdio`
// will be called from there.
//
specs: [
'./test/specs/**/*.js'
],
// Patterns to exclude.
exclude: [
// 'path/to/excluded/files'
],
//
// ============
// Capabilities
// ============
// Define your capabilities here. WebdriverIO can run multiple capabilities at the same
// time. Depending on the number of capabilities, WebdriverIO launches several test
// sessions. Within your capabilities you can overwrite the spec and exclude options in
// order to group specific specs to a specific capability.
//
// First, you can define how many instances should be started at the same time. Let's
// say you have 3 different capabilities (Chrome, Firefox, and Safari) and you have
// set maxInstances to 1; wdio will spawn 3 processes. Therefore, if you have 10 spec
// files and you set maxInstances to 10, all spec files will get tested at the same time
// and 30 processes will get spawned. The property handles how many capabilities
// from the same test should run tests.
//
maxInstances: 10,
//
// If you have trouble getting all important capabilities together, check out the
// Sauce Labs platform configurator - a great tool to configure your capabilities:
// https://saucelabs.com/platform/platform-configurator
//
capabilities: [{
// maxInstances can get overwritten per capability. So if you have an in-house Selenium
// grid with only 5 firefox instances available you can make sure that not more than
// 5 instances get started at a time.
maxInstances: 5,
//
browserName: 'chrome',
acceptInsecureCerts: true
// If outputDir is provided WebdriverIO can capture driver session logs
// it is possible to configure which logTypes to include/exclude.
// excludeDriverLogs: ['*'], // pass '*' to exclude all driver session logs
// excludeDriverLogs: ['bugreport', 'server'],
}],
//
// ===================
// Test Configurations
// ===================
// Define all options that are relevant for the WebdriverIO instance here
//
// Level of logging verbosity: trace | debug | info | warn | error | silent
logLevel: 'info',
//
// Set specific log levels per logger
// loggers:
// - webdriver, webdriverio

// If you only want to run your tests until a specific amount of tests have failed
use
// bail (default is 0 - don't bail, run all tests).
bail: 0,
//
// Set a base URL in order to shorten url command calls. If your `url` parameter
starts
// with `/`, the base url gets prepended, not including the path portion of your
baseUrl.
// If your `url` parameter starts without a scheme or `/` (like `some/path`), the
base url
// gets prepended directly.
// baseUrl: 'https://www.amazon.ca/',

//
// Test runner services

// your test setup with almost no effort. Unlike plugins, they don't add new
// commands. Instead, they hook themselves up into the test process.

// =====
// Hooks
// =====
// WebdriverIO provides several hooks you can use to interfere with the test process
in order to enhance
// it and to build services around it. You can either apply a single function or an
array of
// methods to it. If one of them returns with a promise, WebdriverIO will wait until
that promise got
// resolved to continue.

尝试下面的代码，你可以看到结果-
等待期望（文本）.toHaveText（“复选框”）
我看到您包含了
wdio/syncequalsWebdriverio 退休了他们的“同步”选项，但我看到该包包装了所有内容以使其再次同步。也许它并不能 100% 完成工作。
在（正常）异步操作中，您需要等待异步函数的结果，例如
.getUrl(await browser.getUrl()) === "https://the-internet.herokuapp.com/"
expectawait expect(browser).toHaveUrl("https://the-internet.herokuapp.com/")
或者寻找片段，例如
await expect(browser).toHaveUrl(expect.stringContaining('the-internet.herokuapp.com'))
