在Windows 7上使用Axe辅助功能工具运行Node js脚本时遇到问题

Question

我正在运行从 https://www.npmjs.com/package/axe-reports 中找到的这个脚本，为 Axe 可访问性工具创建人类可读的报告。我正在运行示例：

var AxeBuilder = require('axe-webdriverjs'),
AxeReports = require('axe-reports'),
webdriver = require('selenium-webdriver'),
By = webdriver.By,
until = webdriver.until;
var driver = new webdriver.Builder()
.forBrowser('chrome') //or firefox or whichever driver you use
.build();
var AXE_BUILDER = AxeBuilder(driver)
.withTags(['wcag2a', 'wcag2aa']); // specify your test criteria (see aXe documentation for more info)
AxeReports.createCsvReportHeaderRow();
driver.get('https://www.google.com');
driver.wait(until.titleIs('Google'), 1000)
.then(function () {
AXE_BUILDER.analyze(function (results) {
AxeReports.createCsvReportRow(results);
});
});
driver.get('https://www.bing.com');
driver.wait(until.titleIs('Bing'), 1000)
.then(function () {
AXE_BUILDER.analyze(function (results) {
AxeReports.createCsvReportRow(results);
});
});
driver.quit();

这是我得到的错误：

Answer 1

试试这个：

var selenium = require("selenium-webdriver"),
AxeBuilder = require("axe-webdriverjs"),
AxeReports = require("axe-reports");
describe("Accessibility", function() {
var driver;
beforeEach(function(done) {
driver = new selenium.Builder().forBrowser("chrome").build();
driver.get("https://www.google.com").then(function() {
done();
});
});
// Close website after each test is run (so it is opened fresh each time)
afterEach(function(done) {
driver.quit().then(function() {
done();
});
});
it("should analyze the page with aXe", function(done) {
AxeBuilder(driver).analyze(function(results) {
console.log(
"Accessibility Violations stored in aXe-test-results, # of violations: ",
results.violations.length
);
if (results.violations.length > 0) {
AxeReports.processResults(results, "csv", "aXe-test-results", true);
}
expect(results.violations.length).toBe(0);
done();
});
});
});

你可以使用斧头剧作家。此软件包包含您可以直接使用的包装器功能。

• 将库添加为依赖项：

npm i -D axe-playwright

• 在正确page的上下文中注入axe

beforeAll(async () => {
browser = await chromium.launch();
page = await browser.newPage();
await page.goto(`http://localhost:3000/login`);
await injectAxe(page);
});

• 执行自定义命令以使用剧作家扫描辅助功能

it('simple accessibility run', async () => {
await checkA11y(page);
});
