End-to-end testing is a process of verifying the entire functionality of a system, from start to finish. By simulating real-world user interactions with your website, you can identify any errors or glitches that may occur. This type of testing is essential for ensuring that your website is functioning properly and providing a positive user experience.
In this article, we'll discuss what end-to-end testing is, its benefits, and how to perform it on your own website.

What is end-to-end testing and what are its benefits?
End-to-end testing verifies the functionality of a system from start to finish. This type of testing simulates real-world user interactions with your website, such as clicking on links, filling out forms, and making purchases. By testing the entire system, you can identify any errors or glitches that may occur.
End-to-end testing is essential for ensuring that your website is functioning properly and providing a positive user experience.
An example of end-to-end testing
One pretty common example would be testing a shopping website's checkout process. This would involve adding items to the shopping cart, entering shipping information, and completing the purchase. By testing all of these steps, you can identify any errors that may occur during the checkout process.
Here is an end-to-end test of a checkout process completed with UIlicious:
You can see the full script that we used to automate this test with UIlicious here.
If you are interested to know more about this tool, you can find several similar examples of automated end-to-end tests run with UIlicious on this page.
Benefits of end-to-end testing
There are many benefits to end-to-end testing, including:
Improved website quality
By identifying and fixing errors before your website goes live, you can improve the overall quality of your site. This will help to ensure a positive user experience for your visitors.
Reduced development costs
By identifying errors early on in the development process, you can save time and money that would otherwise be spent on fixing them later. Because end-to-end testing can be performed early and often (even when you sleep), it can help to reduce the overall cost of website development.
Improved customer satisfaction
By providing a website that is error-free and easy to use, you can improve customer satisfaction and loyalty.
Faster website development
End-to-end testing can help to speed up the overall development process by identifying errors early on.
How to perform end-to-end testing on your website
There are a few different ways to perform end-to-end testing on your website.
Manual vs. automated testing for end-to-end tests
First, you will need to choose if you want to run your end-to-end test manually or assisted with an automation tool. We have already written an in-depth article that shows the pros and cons of both testing methods if you want to know more about them.
Manual testing
Manual testing is the process of manually testing your website for errors. This can be done by going through each page of your site and checking for any issues.
To perform manual testing, you'll need to have a good understanding of how your website works and what you're looking for.
Automated testing
Automated testing is the process of using software to automatically test your website for errors. This is a more efficient way to test your site, as it can be done on a larger scale.
There are many different tools available for automated testing. Some of the most popular ones include Selenium, Cypress, and UIlicious.

A step-by-step guide to starting doing end-to-end tests
There are a few things you need to do to prepare for end-to-end testing:
1. Choose the right tool
Many different tools can be used for end-to-end testing, each with its own advantages and disadvantages. Because each tool has its own approach on the way to testing, monitoring, and making use of report data.
For example, UIlicious was designed to be a flexible automated testing tool that can be used by anyone, even people who don't know how to code. It uses a unique scripting language that can be easily understood by people that are unfamiliar with coding and QA in general.
2. Identify your goals
Before you begin testing, it's important to identify what you hope to achieve. This will help you to choose the right tool for your needs and focus your testing efforts.
For example, if you're interested in reducing the number of errors on your website, you may want to focus your testing on areas of your site that are known to be buggy or critical in your user journey.
3. Decide on a scope
After you've identified your goals, you need to decide on a scope for your testing. This will help you to focus your efforts and avoid testing areas that are not relevant to your goals.
For example, if you're only interested in reducing errors on your website's homepage, you may want to limit your testing to just that page.
4. Create test cases
Once you've decided on a scope, you need to create test cases. Test cases are a set of instructions that tell the tester what to do and what to look for.
Creating test cases can be done manually or with the help of an automation tool. If you're using an automation tool, you may be able to automatically generate test cases based on your website's structure. But this will need a little preparation work from your side.
5. Execute the tests
After you've created your test cases, it's time to execute them. This can be done manually or with the help of an automation tool.
If you're doing manual testing, you'll need to follow the instructions in each test case. For automated testing, you'll need to run the test cases through the tool.
6. Analyze the results
Once the tests have been executed, it's time to analyze the results. This will help you to identify any errors that were found and fix them.
For automated testing, most tools will generate a report that shows the results of the tests. For manual testing, you'll need to go through the test cases and check for any errors.
7. Fix the errors
After you've identified the errors, it's time to fix them. This can be done by changing the code or configuration of your website.
8. Retest
Once you've fixed the errors, you need to retest your website to make sure that the changes you've made have fixed the problem.
This can be done by repeating the steps in this guide. Once you're confident that your website is working correctly, you can move on to the next phase of testing.
9. Deploy your website
After you've tested your website and made sure that it's working correctly, you can deploy it to your live server.
End-to-end testing is a vital part of any website development process. By doing end-to-end tests, you can be confident that your website is working correctly and that users will have a positive experience.
Resources and tools for end-to-end testing
There are several resources and tools that can help you with your end-to-end testing. Here are a few that we recommend:
UIlicious:
UIlicious is an automated testing tool that can be used to test web applications. It uses a unique scripting language that makes it easy to understand and use.
It uses a scripting language similar to spoken language. For example, the script below will let verify that you receive an error message on Netflix if you enter fake credentials:
I.goTo("https://www.netflix.com/");
// Close the cookie banner
if(I.see$("Netflix and third parties use cookies")){
I.click("Accept")
}
// Login
I.click("Sign In");
I.fill("Email", "[email protected]");
I.fill("Password", "password");
I.click("Sign in");
I.see("Sorry, we can't find an account with this email address.");UIlicious is also automatically generating in-depth reports that you can share in a variety of formats. For example, you can embed them to a web page, like this:
