Our engagement

Recognizing the critical importance of robust quality assurance processes, Dootrix engaged DeviQA’s specialists to quickly scale its QA capabilities. Having joined the project at its outset, our QA engineers are on a mission to support the in-house QA team in ensuring the functionality, usability, and reliability of the mobile application before launch.

Our manual QA engineer has tested the application across various devices, operating systems, and user scenarios. He executes comprehensive functional testing to ensure that all features work as intended while also paying attention to usability, accessibility, and compatibility aspects.

Our automation QA engineers, in turn, have established mobile and backend automation processes for frontend and backend teams from scratch. They’ve set up several automation pipelines that execute automated user scenarios using different configurations as part of the development and release process. Implemented automation testing helps identify various bugs and speeds up the testing of the application.

DeviQA’s QA engineers have smoothly integrated into the Dootrix team by building collaborative relationships, following the existing workflows and corporate culture, delivering results, and offering valuable suggestions. Due to our contribution to systematic testing, collaborative approach, and commitment to continuous improvement, the development lifecycle has been streamlined, and the delivery of a high-quality app has been ensured.

Services provided

Automation testing

We have automated regression tests for mobile frontend and backend parts and integrated them into the CI/CD pipeline. Additionally, our experts have created configurable cross-device and cross-platform automated pipelines that execute tests on real devices in parallel. An initial test suite with load tests has also been developed and integrated into Azure DevOps pipelines. Load performance tests have been extended and adjusted by another performance engineer.

Mobile testing

Our engineers have created over 400 test cases that cover all functional requirements and are regularly executed on various devices and operating systems. Smoke testing is carried out for each build to ensure app stability. Overall, 100 bugs have been identified and reported in the course of manual testing.

Staff augmentation

Our two automation QA engineers and one manual tester joined the Dootrix team to quickly expand its capabilities. They diligently create and update all essential test documentation, write test cases, develop and maintain test scripts, and execute tests. Thanks to flexible working hours, they can promptly address issues throughout the international team's working day, significantly reducing the risk of clients encountering problems.
