End-to-end testing is a critical phase of the QA process, in which the entire application flow is thoroughly tested from start to finish in order to ensure seamless functionality and performance. Unlike unit testing and integration testing, which focus on individual components or modules, end-to-end testing evaluates the interaction between various software components, systems, and dependencies, simulating real-world user scenarios. Since 2010, DeviQA has served companies across diverse domains, such as Healthcare, FinTech, Real Estate, Cybersecurity, Retail, AdTech, and others. Armed with extensive domain expertise and profound technical knowledge, we deliver superior end-to-end testing services that enhance the quality of your software products.

Our Solutions For Your End-to-End Testing Challenges

At DeviQA, we create tailored solutions that address challenges related to e2e testing, providing you with reliable, high-performance applications that meet and exceed user expectations.

Complex Application Flows


As applications become more and more complex with numerous interconnected modules, APIs, and third-party integrations, end-to-end testing turns into a real challenge. Coordination of test scenarios across different layers and environments often leads to bottlenecks, delays, and incomplete coverage.


Our team specializes in dissecting complex application flows and devising comprehensive end-to-end testing strategies. By leveraging advanced test automation frameworks and tools, we streamline the testing process, ensure thorough test coverage, and mitigate the risks associated with an intricate application architecture.

Data Dependency and Management


End-to-end testing often involves scenarios where data dependencies play a crucial role. Managing test data, ensuring its integrity, and orchestrating data-driven test cases can pose significant challenges, especially in dynamic environments.


We implement robust data management strategies tailored to your specific testing needs. From data generation and manipulation to database state management and data-driven testing frameworks, our solutions ensure consistent and reliable data handling throughout the testing lifecycle.

Regression Testing Efficiency


As applications evolve and new features are added, regression testing becomes a critical aspect of end-to-end testing. However, conducting thorough regression tests manually can be resource-intensive and time-consuming.


We employ robust regression testing frameworks and automation scripts to expedite the regression testing process while maintaining test coverage and accuracy. By identifying regression test suites, prioritizing test cases, and leveraging continuous integration pipelines, we optimize efficiency and minimize regression risks.

Types of End-to-End Testing We Perform

Our comprehensive services cover the key types of end-to-end testing to ensure a seamless user experience.

Horizontal E2E Testing

Horizontal e2e testing involves testing across different layers to ensure smooth communication between them and seamless functionality. We meticulously examine how data flows from one module to another, verifying that each component integrates correctly. This type of testing ensures that your software operates cohesively, like a well-oiled machine, eliminating any potential bottlenecks or compatibility issues.

Vertical E2E Testing

Vertical E2E testing checks the functionality and performance of an individual module from top to bottom. We assess how well it meets its intended purpose and interacts with external systems or interfaces. By conducting vertical E2E testing, we can pinpoint and address any potential issues within a specific component, ensuring its reliability and effectiveness within the larger system.

Read Story

Dev capacity:



Didn’t have a formal QA process

Built smooth and well-working processes

Didn’t make automated testing

Test automation : smoke, API, UI on all supported browsers

Testing was carried out by the devs

Full coverage of the application by test cases

Read Story

Test coverage :



Existing workflow in Jira didn’t allow to understand how many bugs were left unfixed before the release and their priorities

Adjusted the Jira workflow, integrated TestRail with Jira to be able to see statisticls of the issues per release

The lack of test documentation

Developed necessary test artifacts that adhere to industry standards and are easily maintainable

No Automation test coverage

Added multithreading to run tests in parallel on 10 different threads, which reduced the time of the test run in 7 times
