AWS Transform for.NET Unit Test Generation

AWS announced that AWS Transform for.NET can now automatically generate unit tests for modernized code. This feature targets testable classes in your transformed.NET application, such as business logic and controllers, providing an automated test safety net as part of the migration job.

Modernizing a.NET Framework application to modern.NET now includes automatically generated unit tests, eliminating the need to manually write test coverage for the modernized code. AWS Transform assesses your application for testability, plans which classes and methods to cover, and generates the corresponding unit test code.

What to do

  • Enable unit test generation at the start of a job or after transformation completes.
  • Use the AWS Toolkit for Visual Studio extension to run a.NET transformation with AWS Transform for.NET in Visual Studio and choose to generate unit tests.
  • Refer to the Modernizing.NET in the IDE section in the AWS Transform User Guide for more information.
