      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

Here are some of the QA tests that US .NET development companies employ: 

  • Unit testing: Examines the software’s individual components, including module behavior, code-level functions, and error handling

  • Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together 
  • Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
