Review

As our company transitions out of the startup phase and begins signing larger clients, we face the challenge of rapidly adding new features to meet their needs without compromising the quality our early clients value. To address this, we partnered with DeviQA for testing support. Automation plays a pivotal role in ensuring consistent quality while enabling quick and reliable product updates. Our collaboration with DeviQA focuses on building a dependable suite of automation regression tests for our mobile and web applications. Using open-source tools and standards, they developed a test framework based on guidelines I provided, and they have taken full responsibility for its coding and maintenance. Currently, their team handles everything from integrating the framework with other tools to creating new tests, monitoring execution, analyzing failures, and updating obsolete tests. The workflow is highly efficient and straightforward. We hold weekly meetings to review progress and set priorities, with ongoing communication throughout the week to resolve issues or address blockers. A dedicated project manager is available for any team-related concerns, though I’ve only needed to engage with them for expanding the team, as there have been no issues with the collaboration.
