There may be not a variety of documentation out there about what’s Drupal Development Service distinction between operating a browser in WebDriver mode vs Headless so I did some digging… by Jibran Ijaz / 14 August 2021 Apparently, there are two methods to run Chrome for testing Drupal 10 Upkeep and Assist Service As WebDriver As Headless WebDriver Drupal 10 Upkeep and Assist Service There are two methods to run Chrome as WebDriver Drupal 10 Upkeep and Assist Service Utilizing Selenium Drupal 10 Upkeep and Assist Service Run Selenium standalone server in WebDriver mode and cross Drupal Development Service path of ChromeDriver bin together with Drupal Development Service config e.g. Selenium Dockerfile This works fantastic with Nightwatch commonplace setup, FunctionalJavascriptTestsJavascriptTestBase and in addition with core’s new FunctionalJavascriptTestsWebDriverTestBase. Utilizing ChromeDriver Drupal 10 Upkeep and Assist Service Run ChromeDriver in WebDriver mode e.g. chromedriver Dockerfile This works fantastic with Nightwatch, JTB, and WTB. Headless Drupal 10 Upkeep and Assist Service Utilizing Chrome Run Chrome browser binary in headless mode. e.g. Chrome headless Dockerfile Nightwatch just isn’t working with this arrange, not less than I used to be unable to configure it. See https Drupal 10 Upkeep and Assist Service//github.com/nightwatchjs/nightwatch/points/1390 and https Drupal 10 Upkeep and Assist Service//github.com/nightwatchjs/nightwatch/points/1439 for more information. DMoreChromeDriver can be utilized to run Drupal Development Service javascript assessments. Utilizing ChromeDriver Utilizing Selenium ChromeDriver might be run in headless mode one thing like this Drupal 10 Upkeep and Assist Service const fs = require(‘fs’); const webdriver = require(‘selenium-webdriver’); const chromedriver = require(‘chromedriver’); const chromeCapabilities = webdriver.Capabilities.chrome(); chromeCapabilities.set(‘chromeOptions’, {args Drupal 10 Upkeep and Assist Service [‘–headless’]}); const driver = new webdriver.Builder() .forBrowser(‘chrome’) .withCapabilities(chromeCapabilities) .construct(); CI is operating ChromeDriver with out Selenium and testing Nightwatch and WTB on it. Conclusion Drupal Development Company query is which is Drupal Development Service finest answer to run Nightwatch and JTB/WTB assessments utilizing Drupal Development Service identical setup? We had seen some reminiscence points with Selenium containers in Drupal Development Service previous however we’ve not run into any subject lately so I desire this and you may swap Selenium container to make use of completely different browsers for testing. We have now additionally seen some points whereas operating ChromeDriver in WebDriver mode. It simply stops working mid-test runs. I used to be unable to get Headless Chrome working with Nightwatch however it wants extra investigation. Headless ChromeDriver setup on CI is sort of steady. For JTB this may imply that we may use anybody from FunctionalJavascriptTestsSelenium2Driver and DMoreChromeDriver. Please share your concepts and ideas, thanks!
