Providing a greater quality application leaves a good impression on the user. To achieve excellent quality and to confirm that it is at its best you need to test your application thoroughly. Applications today are becoming more complex. They are developed on layers and entire networks of subsystems, including UI and API layers, external databases, networks, and third-party integrations. The entire application fails when any of these goes wrong or breaks down.
Making the stability of each element is vital for the success of an application and cannot be compromised. Hence it is important to test the entire application, from start to finish. The major risk of failing an application can be avoided by end-to-end testing.
Previously testing used to be a tedious task but with the advent of automation, automated testing came to the rescue. With the growing development of applications, the number of automated testing tools is also multiplying at speed. They allow your team to maximize test coverage and find out new bugs in an exploratory fashion.
In this article, we will be talking about the end-to-end testing frameworks. But before moving it would be better to start with a brief introduction to what end-to-end testing is and why is it important to perform this testing?.
What End-To-End Testing is?
End-to-end testing is a process of testing the functionality and performance of an application under user-like circumstances and data to replicate live settings. The objective of end-to-end testing is to simulate what a real user scenario looks like from start to finish. It is done from start to finish under real-world scenarios like communication of the application with hardware, network, database, and other applications.
The testing is completed by validating the application under test and its components for integration and data integrity. It also ensures that its subsystems work and behave as expected.
Describing it technically, when testing is completely done, it is necessary to perform “End to End testing”. It help find out various dependencies of an application as well as to ensure that accurate information is communicated between various application components.
It is a one-stop solution for the different workflow of an application. As it tests the whole application in a user-like environment by imitating their action, network, communication, etc. This type of testing approach ensures application health with no defects left and user satisfaction.
The main objective remains here is to provide an excellent users experience by optimizing the functionality of the application
End-to-end testing is an integral part of application development; it can be run by automation as well as by using manual testing tactics. But automated testing allows you to half the time you spend on testing your applications.
Why perform End to End testing
A modern application system comprises its interconnection with multiple sub-systems. This has made modern software systems very complicated. If there is any failure or fault in any sub-system, it may affect the whole application system and lead to failure.
There is always a purpose in testing to make it meaningful and productive. And the same is with end-to-end testing. Why do we need to perform End to End testing? Let’s find it out here.
- To ensure that the application is well coordinated and functional with all of its sub-systems.
- Ensuring that the application behaves as intended across the different environments.
- Checking whether the flow of data is maintained for different user’s tasks and processes.
- Validating every aspect with the end user’s perspective by simulating real-world scenarios.
- Identifying various defects and breakdowns in the environment and increasing productivity.
- Detailed testing each step of the way, end-to-end testing will decrease the need to repeat tests, and simultaneously reduce the costs and time associated with doing so.
Now, when you have a fair understanding of end-to-end testing, let’s take a look at some of the frameworks used for end-to-end testing.
The tool also provides you with features such as time travel, video recording, and image capturing that allows you to capture screenshots of your web applications and enables you to playback the state of the tests over time. Hence you can thoroughly and effectively assess bug issues during your application test and get a clean and accurate result.
This open-source tool allows you to write automated scripts for web applications under different platforms and also on multiple browsers and verifies the website’s correct functionality. Selenium is considered to provide efficient and faster test execution as it directly interacts with the browsers. You can also use Selenium for cross-browser, and web testing.
Selenium has a wide range of functions and features that help in simulating almost every action a user would perform. Features it provides are record and playback testing, and parallel test execution, which is integrable with other frameworks also.
Cucumber focuses on end-user experience, hence is a good option for end-to-end testing. This tool helps you to build an application by considering the perspective of developers, QAs, and customers. The main reason for Cucumber’s popularity is that it is simple and easy to set up.
A non-technical person who doesn’t have higher skills in programming, and is unable to write tests in complex codes, Cucumber makes it easy for them to write and understand the test scripts.
To define test cases in Cucumber the developers use Gherkin, which is very similar to writing statements in simple English so that they can be read and understood by anyone.
Katalon Studio is a test automation tool that makes your end-to-end tests effortless. It provides testing for mobile, desktop API, and Web UI. It allows the creation of test reports with real-time notifications and insightful graphs after each execution.
Katalon Studio mainly provides three features that are a recorder, to record your steps on the application so that you can watch them accomplish the task of creating a hassle-free user journey.
Another feature is built-in keywords, this allows you to verify a web element that you expect to contain against certain text, or its properties against some expected properties and you can check many other types of expectations.
And lastly, the custom keywords. The behaviors of your application that occur across different pages but differ only in some known characteristics. So the best practice is to capture these behaviors in a behavior template. When necessary they can later be filled with specific information. This is what a custom keyword is. Once defined, you can reuse them in different test cases and even in different test projects.
testRigor helps the testers to create complex end-to-end test automation processes smoothly and quickly with plain English language statements. It seamlessly creates and builds tests across multiple browsers and operating system combinations, including Android and iOS devices, with no technical knowledge of coding required.
It has the functionality for API, calls, emails, and SMS, testing. The tool also provides a record-and-playback feature and can be integrated with CI/CD tools as well as with major issues and tracking systems. Instead of focussing on repetitive tasks, testRigor allows testers to focus on new feature testing and edge cases. These are some of the features that make it on the list.
Performing End-to-End testing using LambdaTest
With LambdaTest, you can perform Selenium automation, Cypress test automation, Playwright automated testing, Geo-location testing, parallel testing and more on a wide range of platforms and share the test result screenshots with the team without any hassle. There are a lot of integrations available for debugging and enhancing the quality of team communication.
LambdaTest is ideal for automating end-to-end tests because it works across different browsers, operating systems, and web applications. It allows you to run automated end-to-end tests to expand test coverage, reduce time and costs, and ultimately gain confidence with each release.
To get all the benefits out of your end-to-end testing you need to have the right framework in place. A wrong one can be a waste of time and money. Go for the one that provides smarter testing, productivity benefits, and better overall results for your entire testing.
I hope that the above information helps you on the road to the best end-to-end testing framework for your needs.
