Selenium Automation Testing in Cross Browser

We will get into cross-browser testing in this article. It is a type of testing that determines whether a programme performs as intended on various browsers, operating systems, and gadgets. Cross-browser testing can be done both automatically and manually. Attempts like and Selenium Automation Testing can be used to record or build the automation test scripts.

You will learn What Is Cross Browser Testing, the Advantages of Cross Browser Testing, and How to Implement Cross Browser Testing in Selenium by the end of this post.

Cross-Browser Testing: What It Is

Our Application under Test (AUT) is tested across several browsers, operating systems, and devices to assure compatibility. Comparing the anticipated behaviour of an application across various instances is the goal. The same Test Script may occasionally succeed on one or more instances while failing on another.

Maybe the application or our test script is to blame for the failure. Have you ever used Internet Explorer to open a webpage and it failed? Then used Chrome to open the same website without incident. These problems are discovered during cross-browser testing since each browser renders an AUT's data in a unique way.

 

Cross-Browser Testing Advantages

Setting a baseline is the first step in implementing cross-browser testing. An average Test Script serves as a baseline. The goal is to assess how well our AUT works with a single browser, single operating system, and single device. Then, by using more configurations of browsers, operating systems, and devices, we can expand upon the baseline.

I'll concentrate on these two advantages of cross-browser testing:

 

1. Time

2. Test Coverage

 

Time

The writing and running of each individual Test Script for distinct circumstances takes time. As a result, our test scripts are written to run different data combinations. For the initial iteration, the same Test Script can run on Chrome and Windows, then on Firefox and Mac, and finally on more situations for later iterations.

Because we only needed to build one Test Script rather than several for each case, we were able to save time. The following two lines of code load the TestProject's Example page and retrieve its title, respectively. Cross-browser testing is one example, and the second example uses separate test scripts for three different browsers (Chrome, Firefox, and Edge).

 

Exam Coverage

Using a technique called test coverage, we can figure out what and how much of our test scripts are covered. We determine the features and confirm that sufficient Test Scripts are available for those features. Benefits of test coverage include the ability to assess the effectiveness of our test cycles.

Depending on the needs, our test scripts cover different topics.

Our test scripts cover a variety of topics, depending on the browsers and their various browser versions.

 Test coverage serves as a useful barometer for our testing procedure. However, achieving 100% coverage is challenging, and it's conceivable that a feature performs oddly depending on the version.

 

How to Conduct Selenium Cross Browser Testing

Using Selenium's Grid or test data, we can perform cross-browser testing. Selenium Grid streamlines the procedure while accepting test data as input. Our test scripts are run concurrently on many remote workstations using Selenium Grid. A client sends the instructions to distant browser instances.

Test data can be kept in a database, Excel file, CSV file, properties file, or XML file. For Data Driven Testing or Cross Browser Testing, we can also mix TestNG with the test data. The DataProvider Annotation, dataProvider Attribute, or dataProviderClass Attribute enable our test script to receive an infinite number of values for data-driven testing.

When it comes to cross-browser testing, we can submit alternative browser names using the parameter tag and the Parameters Annotation. The code snippets that follow show an XML file with the parameter tag and a test script annotated with parameters.

The parameter tag is found at the test level of the XML file. The tag can be added at the test level, the suite level, or both levels. A name and value are enclosed in double-quotes in the parameter tag. Its value, "Chrome," is supplied to the if or else if statements while its name, "BrowserType," is passed to the Test Script via the @Parameters Annotation.

Chrome, Edge, or Firefox are configured via the if and otherwise if lines. Following execution from the XML file, the same Test Script sent commands to every browser. The test results listed below demonstrate how the page loaded correctly and how the console printed the specific browser name and Page Title.

Test coded for OpenSDK

When utilising, there are two approaches to carry out Cross Browser Testing. The AI-Powered Test Recorder or the open-source OpenSDK are both options. Java, C#, or Python are supported by the OpenSDK, which wraps over Selenium. Our test scripts are very similar to Selenium's Cross Browser Testing in regard to dependencies and code. The browser drivers must be imported, the token must be passed, and Maven or Gradle dependencies must be included.

 

Summary

In conclusion, cross-browser testing is a fantastic approach to use one test script across different browsers simultaneously. Time and test coverage are a couple of the advantages. We save time by avoiding writing numerous Test Scripts for each browser. Another advantage is that we can test more than just the browser version for a given browser, which increases test coverage.

Selenium Automated Testing are used for Cross Browser Testing. After integrating the free OpenSDK, enables us to produce our own Test Scripts in Java, C#, or Python. Since the OpenSDK is a Selenium wrapper.
