Difference Between UAT vs E2E Testing (2024)

FAQs

Difference Between UAT vs E2E Testing? ›

UAT focuses on verifying the system meets business requirements from an end user's perspective. E2E testing focuses on verifying system integration and E2E workflows.

UAT ensures that the software meets the business requirements and user expectations, while E2E testing validates the entire system's functionality and data integrity.

Integration testing concentrates on the interaction between different software modules or components. It ensures that these modules or components can communicate with each other and exchange data correctly. End-to-end testing, on the other hand, focuses on the whole software system from start to finish.

Usability testing tells us about user behaviour, user pain points, user feedback, user suggestions while they interact with a product or service, while User Acceptance Testing focusses on the entire functionality of the software application.

UI Testing is narrower in scope, focusing on the user's interaction with the application's interface. It verifies all possible user actions, including error handling and input validation. E2E Testing has a broader scope, covering the entire application workflow.

The Difference between Unit Testing and End-to-End Testing is that Unit testing ensures that the functions or calculations that generate data, a numerical value, a text string, are working as required. End-to-end testing ensures that buttons, forms, updates, links, and the complete workflows work properly.

SIT is done first, after system assembly, as it focuses on testing the integration of different system components. While UAT is done before product release, from an end-user perspective, to ensure that the product meets their requirements and expectations.

The Cons of E2E testing

This test pyramid approach needs to be modified for testing microservices. E2E tests need to be completely dropped. Apart from taking a long time to build and maintain, E2E tests execute complete user-flows every time on the entire application, with every test.

Component tests focus on testing individual components of an application in isolation, while Cypress E2E tests test the application as a whole, including all its components and their interactions. Due to the narrower scope, Cypress component tests require less setup and are easier to write, debug, and maintain.

What is the difference between UAT and acceptance testing? ›

User Acceptance Testing (UAT): This involves verifying the user's requirements have been met. Business Acceptance Testing (BAT): Here, you assess whether the product meets the business goals set out in the design. Contract Acceptance Testing (CAT): These tests happen once a product goes live.

User Acceptance Testing (UAT), or application testing, is the final stage of any software development or change request lifecycle before go-live. UAT meaning the final stage of any development process to determine that the software does what it was designed to do in real-world situations.

User acceptance testing is performed by the end-users. With that said, it is QA team that will be in charge of running user acceptance testing. They will write a complete UAT test plan, prepare a UAT environment that mirrors production, and write corresponding UAT test cases.

UAT helps catch any issues related to user needs and usability, while E2E testing ensures that all components of the software function correctly together, ultimately leading to a smoother user experience and higher software quality.

1) System Testing helps identify and mitigate risks associated with individual components, ensuring they meet specified requirements. 2) End-to-End Testing provides a more holistic view of the system's behavior, uncovering potential issues related to integration, data flow, and user interactions.

End-to-end tests are like functional testing in that they consider the user experience. However, differences between the two include the following: Scope. Functional tests validate the input and output result of each test, while E2E tests validate that each step in the process can be completed from start to finish.

End-to-end (E2E) testing is a software testing methodology that verifies the working order of a software product in a start-to-finish process.

User Acceptance Testing (UAT) and System Integration Testing (SIT) are two great examples to dive in deeper and review. UAT represents testing whether an application meets the business need whereas SIT represents the testing of an application to ensure it meets its engineering specifications.

One of the best practices to transition from UAT to production is to deploy the product gradually. This means releasing the product in phases, segments, or batches, rather than all at once. This allows you to monitor and evaluate the product performance, user feedback, and business impact in real time.
