Create and implement a test plan for their mobile devices in the Hardware Abstraction Layer team. This included the following: ● Convert and setup projects to allow mobile testing ● Convert existing tests to xUnit ● Train teams in using mobile devices for testing ● Create pipelines in Azure Devops for build, test and deploy of mobile apps ● Execute tests on device farm and gather results for test documentation ● Setup & document manual tests ● Automate smoke & integration tests ● Share knowledge and assist developers in development for mobile on Android & iOS.
Hereafter I worked on a custom hearing aid emulator. Which would greatly help development and testing of new hearing instruments before they were available for internal development use. Initially it was only running local, but the client wanted to extend usage. Therefore we moved it into Azure Appservices.
● Docker ● Virtual Networks, Deployment slots swapping, Redis etc ● Created automated build, test deploy scripts for services in Azure using BICEP ● Train other testers and users in the usage of the emulator The client's code base was a monolith, and I helped on extracting the team's components into their own git repository. This of course would require new pipelines configured in Azure Devops and integration between all the new repositories.
● Create overview of existing pipelines from on-prem Azure Devops and extract them into Azure Devops.
● Create new pipelines to support their CI/CD strategy ● Ensure projects and codebase are aligned with requirements from architects.
My last task within the company was to refactor their existing CI pipeline between all repositories for communication with the hearing aids. This included implementing an artifact management system to be used among all their repositories. This meant having a lot of customers with different requirements and needs. A simple, decoupled framework independent solution was implemented. Each team was able to easily integrate their specific pipelines into the new system.
Other things to mention: ● Refactor code for dependency injection and IoC usage.
● Trained teams in Azure, Xamarin, Test principles, improvement of architecture, DRY, IoC, mocks, KISS etc.
● Implementation of new hearing aid communication protocol, including testing.
