Our engagement

Diverse skills were required to test a secure E2EE mobile messenger properly, from automation and manual QA expertise to the adaptability of our QA Lead, who seamlessly transitioned into the roles of a Scrum Master and a Project Manager.

Facing challenges head-on, first and foremost, we created a testing strategy that hadn’t been in place before, updated outdated documentation, introduced test automation strategically, streamlined the development process, and ensured the integration of crucial missing features.

Throughout the project development, we achieved significant milestones:

  • implemented E2EE automation regression testing for the iOS and Android apps;
  • maintained comprehensive test case coverage by updating manual test cases;
  • established a seamless testing process, enhancing overall efficiency.

Our streamlined testing process facilitated more than 7 successful and on-time releases.

Recognizing issues in the development process, we assumed the roles of a Scrum Master and a Project Manager and introduced Scrumban for agile development. Our experts refined the QA and development processes, optimized bug tracking in Jira, and crafted user stories with clear acceptance criteria.

Our engagement in the project was a game changer. We redefined processes, introduced agile methodologies, and consistently delivered feature-rich releases. Our efforts resulted in a robust, user-friendly, and secure E2EE mobile messenger.
