Selenium is a portable testing framework for web applications. Selenium provides a record/playback tool for authoring tests without learning a test scripting language (Perl, PHP, Java, etc.).

JavaScript is one of the most popular programming languages in the world. Selenium is a powerful tool for testing web applications.

Using JavaScript with Selenium can help you test your skills and make sure your code is working properly. Here are some tips for using JavaScript with Selenium.

Selenium is also used in automation. Automation is the process of automating manual tasks. This means that instead of performing the task manually, the task is performed by a machine or software.

Intro to JavaScript and testing using javascript

JavaScript is a programming language that can be used to add interactivity to websites. It is also used in server-side programming, game development and mobile app development.

JavaScript is easy to learn for beginners and has many features that make it attractive to experienced programmers.

Selenium is a powerful testing tool that can be used to test software written in a variety of programming languages, including JavaScript.

If you’re new to Selenium, you may be wondering why you should use it over other testing tools.

The answer is simple: Selenium is extremely versatile and can be used to test applications of all types, sizes and complexity. Plus, it’s free and open source!

To get started using Selenium with JavaScript, you’ll need to install the Selenium WebDriver.

How much javascript really needed for selenium testing.

You don’t have to be a java whiz to be a selenium automation expert.

You can learn it using flow concepts in webdriver, along with a strong understanding of processes and some hands-on experience on objects, states, and bare-bones programming.

Selenium is a web application testing tool that supports multiple browsers and can be scripted in various programming languages. One of these languages is JavaScript, and it’s often used for testing because it’s easy to learn and use.

However, some people believe that you don’t need to know much JavaScript in order to use Selenium effectively. While it’s true that you don’t need to be an expert in the language, there are certain things that you should know in order to get the most out of Selenium.

For example, knowing how to select elements on a page and how to work with the browser’s console will make your life as a tester much easier.

If you’re not sure where to start, there are plenty of resources online that can help you learn the basics of JavaScript for Selenium testing.

Here we have some basics of javascript that is going to be used in selenium automation testing using Selenium WebDriver.

Why do we need to use JavaScript with Selenium.

When it comes to software testing, JavaScript is a language that can provide Selenium users with a number of benefits.

JavaScript can be used to create custom test automation frameworks and to automate tasks that are not possible with Selenium alone. Additionally, JavaScript can be used to improve the performance of Selenium tests by making them more efficient.

Using JavaScript with Selenium can help testers save time and effort when automating their tests. In some cases, it may even be necessary in order to get the desired results from Selenium.

For these reasons, it is important for testers to have at least a basic understanding of how to use JavaScript with Selenium.

Javascript is required to use selenium because it provides the ability to automate web browsers and test web applications.

For example, javascript can be used to automatically fill out forms, click buttons, and navigate website pages. Without javascript, selenium would not be able to function properly.

Overall, javascript is an essential part of selenium and allows for automated testing of web applications. Javascript makes selenium more efficient and effective,

which is why it is required when using this software testing tool.

Best Practices for Selenium WebDriver with JavaScript

When using Selenium WebDriver with JavaScript, it is important to follow best practices in order to get the most out of the tool and avoid common pitfalls.

One best practice is to make sure that you are using the latest version of Selenium WebDriver. This will ensure that you have access to the latest features and fixes.

I have found some best practices for selenium WebDriver with JavaScript

1. Look for best locator strategy

When it comes to automation testing, one of the most important pieces is the locator strategy. The locator is what tells the test script where to find the element on the page that it needs to interact with.

There are a few different options when it comes to locators in Selenium. The most common are XPath, CSS selectors, and ID.

XPath is a language that is used for locating nodes in an XML document. It has a syntax that allows you to specify where an element is located by its position in relation to other elements.

For example, if you wanted to locate the “username” input field on a login page, you could use the following XPath: //input[@id=’username’]

CSS selectors are another option for locating elements on a web page.

2. Page Object Model

Page Object Model is a design pattern that can be used in selenium to make your tests more maintainable and easier to understand.

There are three main steps to using Page Object Model in selenium:

1. Create a page object for each page you want to test. Each page object should represent a single page in your application and contain all the elements and functionality that you need to test for that page.
2. Write your test cases using the page objects. This means that instead of interacting directly with the selenium webdriver, you will interact with the page objects.
3. Maintain your page objects by keeping them up-to-date as your application changes.

3. Browser Compatibility Matrix

Make sure about all these points:

1. In order to ensure that your selenium scripts will work with the correct browser versions, it is important to maintain a browser compatibility matrix.
2. This matrix should list the browsers and versions that you have tested your scripts with, as well as the ones that are known to be incompatible.
3. By keeping this information up-to-date, you can avoid potential issues when running your tests on different browsers.
4. Additionally, if you find that a certain browser version is causing problems, you can quickly check the matrix to see if it is compatible.
5. If you are having trouble maintaining a browser compatibility matrix, there are various tools and services that can help.
6. These tools can automate the process of checking for updates and incompatibilities, making it easier to keep your testing environment up-to-date.

4. Creating test cases beforehand to plan for a task.

Before starting to code automated tests, it is important to create test cases. This will help plan for the task at hand and ensure that all aspects of the application are covered.

There are a few things to keep in mind when creating test cases. First, think about what you want to test and what you need to do to set up the test.

Next, consider what assertion you will make at the end of the test. Finally, decide how long the test should take to run.

Once you have created your test cases, you can start coding your automated tests in Selenium. Selenium is a powerful tool that can help you create comprehensive automated tests quickly and easily.

With Selenium, you can run your tests on multiple browsers, making it a great choice for cross-browser testing.

5. Test coverage

Test Coverage is a metric that tells us how much of the code is covered by tests. It is a measure of how complete our test suite is.

There are different types of test coverage, but in general, we can think of it as the percentage of the code that is executed when the tests are run.

For example, if our codebase has 1000 lines of code and our tests only cover 500 lines, then our test coverage would be 50%.

One way to increase test coverage is to add more test cases. Another way to increase test coverage is to use a tool that can automatically generate test cases for you.

Selenium is one such tool. It can be used to generate functional tests for web applications. Selenium can also be used to generate load tests and performance tests.

Summary

To become a Selenium Automation tester, one does not need to know an extensive amount of Javascript. However, a basic level of understanding is necessary in order to create automated tests.

Selenium IDE is a great tool for those starting out in automation testing and it requires very little programming knowledge.

Selenium automation testing should have a basic understanding of JavaScript before getting started.

With that said, learning at least some Javascript will allow testers to be more efficient and have more control over their tests.
