What Is End-To-End Testing?

End-to-end testing is a technique that tests the user experience from the user’s perspective and verifies the final result. By using end-to-end testing, you can verify that all critical user scenarios are working smoothly and no major gaps exist. In other words, end-to-end testing makes sure that users can use your website or app and find what they want without stumbling on any roadblocks along the way. This is also known as continuous testing or integration testing. End-to-end testing is usually performed by inputting numerous test cases and monitoring whether the desired output is produced from every one of them. It requires you to record a set of test cases as automated scripts to be able to execute those scripts at any time later in order to check if new features have broken any existing functionality.

End-to-End Testing Tools #

There are a few tools that can be used for E2E testing. Some of the most common are listed below:

Selenium – Selenium is one of the most popular tools for testing websites and web applications. It is an open source tool that can be integrated with all the major software development tools.

SoapUI – This is another popular open source tool for testing web applications and APIs. It can be used for load testing, functional testing, and end-to-end testing.

Gatling – This is an open source tool that can be used for load testing, functional testing, and end-to-end testing.

Appium – Appium is an open source tool that can be used for mobile application testing.

Why Is End-To-End Testing Important? #

End-to-end testing is a critical part of application development. It ensures that your application is robust and complete. The best way to do this is to record a set of tests. This will allow you to run the tests later and check if any new features have broken any existing features. This is the only way to make sure that your application will work correctly when the time comes to launch it.

What Should Be Tested During End-To-End Testing? #

When you are testing the user experience, you will find that some features may be broken. To avoid this, you should test for the following things:

Test for broken links – In every website or application, there will be links. It’s very common for these links to break during development. To avoid this, you should test every link to make sure that it works correctly. 

Test for security – This is very important. You don’t want your application to be hacked and your user information to be stolen. There are lots of tools available that can be used for security testing.

Test for localisation – If you are using your application in multiple languages, you will want to make sure that all languages are supported.

Test for limitations – This is another test that you should perform. You don’t want your application to break at full capacity.

How To Perform End-To-End Testing? #

The best way to perform end-to-end testing is to write an automated script. The script will input the data and click on all of the features that you want to test.

Start with the first test and add a few more as time goes on.

When you are writing the script, you will need to decide if you want to input data manually or if you want to generate it automatically. For example, if you want to test for broken links, you will want to input the link manually and see if it’s broken or if you want to find broken links on the Internet and input those into your application.

Limitation Of End-To-End Testing #

If you are using a single-page application, it will be very hard to perform E2E testing for this type of application.

You will need access to a server that can be used for executing the scripts.

If you are using a third-party application like a payment processing application, you won’t be able to perform E2E testing. All in all, E2E testing is a very important part of application development. However, it is a very time-consuming task. If you are trying to do it manually, it will take a very long time. That’s why most people try to automate this process as much as possible.

Conclusion #

Now that you know what end-to-end testing is and why it is important, it’s time to get to work! Start testing your application to ensure it is working correctly. If you have been putting off end-to-end testing, now is the time to get started.
