Getting Started with Selenium and React

and React are the two popular tools, unique in their own slipway and common in software development and testing circle. React is a JavaScript library meant to make interactive user interfaces. On the former hand, Selenium is used to perform on such user interface and web pages. They are often used in tandem, as this article will demonstrate.

This article will explore how both these instrument go hand in hand and in what cases Selenium and React best fit the test scenarios and environments.

Let ’ s get started!

Introduction to Selenium and React

• Selenium is an open-source tool frequently leverage to test web applications on multiple browsers and operating systems (platforms).
• Reactis an open-source, front-end, JavaScript library oft used to build user interface or UI elements. It is maintained by Facebook and a community of item-by-item developers and organizations. React can be used as a base when developing single-page or mobile applications.

First, let ’ s configure both these tools.

How to configure Selenium

Ensure that Selenium & # 8217; s language bindings are installed and ready by running:

sudo pip install selenium sudo pip install requests

On completing this installment, let ’ s begin writing the first test case.

How to Run React Apps employ Selenium

Setting up the webdriver with the help ofNode.jsis rather simple.

const webdriver = require (`` selenium-webdriver ''); const driver = new webdriver.Builder () .forBrowser (`` firefox '') .build (); // Instantiate a web browser page driver.navigate () .to (Yahoo '');

After configure Selenium WebDriver, go ahead and add control flows to the code. WebDriver methods are asynchronous. For example, place an element with the help of a is an async operation. All asynchronous operations return (Promises) in the Selenium WebDriver, so that testers can concatenation them through thethen() method.

const By = webdriver.By; // useful Locator utility to describe a query for a WebElement driver.navigate () .to (`` Yahoo '') .then (() = & gt; driver.findElement (By.css (`` # login-username ''))) .then (element = & gt; element.getAttribute (`` value '')) .then (value = & gt; console.log (value));

The driver.findElement ()returns a Promise for a WebElement, which is mainly the interface to inspect and manipulate DOM elements in Selenium.

driver.navigate () .to (`` Yahoo '') .then (() = & gt; driver.findElement (By.css (`` # login-username ''))) .then (element = & gt; element.getAttribute (`` value '')) .then (value = & gt; console.log (value)); const until = webdriver.until; // useful usefulness to expect command driver.navigate () .to (“ Yahoo ”) .then (() = & gt; driver.findElement (By.css (' # login-username ')) .sendKeys ('xyz @ yahoo.com ')) .then (() = & gt; driver.wait (until.elementLocated (By.css (' # login-signin ')))) .then (() = & gt; driver.findElement (By.css (' # login-signin ')) .click ()))

Each time the tester invokes an asynchronous WebDriver chore without resolving it, the WebDriver actually pushes this labor to a global queue. As soon as the quizzer settle one promise (usingthen()), or after the following tick of the JavaScript case loop, all queue tasks are executed in the order in which they be scheduled as if they be synchronous. This is called Control Flow.

This is how Selenium exploiter can add React to Selenium Webdriver and integrate the tools for more effective evolution.

Bear in mind that all Selenium tests must be run on real browser and devices for precise resultant. Start running trial on 3000+ real browsers and device on BrowserStack ’ s. Run on its to get fast results without compromising on truth. Detects the bug and offers a high-end UX/UI to the users by machine-driven testing in with.
