Reviews on

Integration testing verifies that individual software modules, when integrated, function together as expected. It identifies communication and data flow issues as well as improves overall software quality by detecting errors early in the development process. Since 2010, DeviQA has served companies across diverse domains such as Healthcare, FinTech, Real Estate, Cybersecurity, Retail, AdTech, and others. Our extensive expertise enables us to develop highly effective test automation solutions, speeding up your development cycles and ensuring the superior quality of your software products.

Our Solutions For Your Integration Testing Challenges

We understand the complexities of integration testing and address them efficiently. Our seasoned team of QA experts leverages innovative testing methodologies and state-of-the-art tools to ensure the seamless integration of your software components.

Complex Ecosystems and Dependencies


Modern applications often rely on a complex net of interconnected systems, making it challenging to ensure seamless integration.


We provide comprehensive integration testing strategies to identify and resolve issues within intricate ecosystems, ensuring a smooth data flow and sound functionality.

Ensuring Data Consistency Across Platforms


Maintaining data consistency across diverse platforms and databases can be a daunting task with a high likelihood of potential integration errors.


Our skilled testing team uses advanced techniques to validate data consistency, preventing discrepancies and ensuring accurate data flow.

Third-Party Integration Risks


Integration with external APIs and third-party services introduces the risk of compatibility issues and unexpected disruptions.


We conduct rigorous testing to identify and mitigate risks associated with third-party integrations, ensuring seamless work of your systems with external services.

Types of Integration Testing We Perform

Our expert team of testers specializes in all integration testing types, each of which aims to protect your software from glitches, ensuring its flawless work.

Top-Down Integration Testing

We begin by testing the highest-level modules and gradually proceed to lower-level ones. This method helps early identify issues in critical functionalities, ensuring a robust and error-resistant software structure.

Bottom-Up Integration Testing

In this case, we take the opposite approach by starting with testing low-level modules and gradually progressing to the high-level ones. Therefore, we can pinpoint and rectify potential issues at the grassroots level, contributing to a reliable and resilient software foundation.

Mixed/Sandwich Integration Testing

We blend the positive sides of both top-down and bottom-up approaches to create a comprehensive testing strategy. This hybrid method is particularly effective in uncovering intricate inter-module dependencies and ensuring a harmonious integration of components.

Big-Bang Integration Testing

We test all modules simultaneously after their development, which allows us to assess the operation of a whole system. Our efficient and meticulous testing protocols ensure that no detail is overlooked during this grand convergence.

Incremental Integration Testing

We rigorously test that every new addition seamlessly aligns with the existing system. This method not only fosters continuous feedback but also minimizes the risk of systemic failures.

Choose Your Cooperation Model

We understand that every project is unique, which is why we provide various cooperation models to cater to different needs. Check them and choose the one that best fits your requirements:

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

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
