• Steps to reproduce the issue:"

1. create new project by using abp suite module template
2. add commercial package to the domain layer (e.g. filemanagement)
3. create a new unit test (no extra step taken after code generation)
4. try to debug/run test

my unit tests are not running when i use commercial volo packages in my module project i believe that is due to their license check

to collect for information regarding error i tried attached data collector to my testhost

datacollector log indicates :

My current abp license allows me to access the commercial module source code. So i just disabled license checker at app init stage

Now i can run my unit test after this modification

Can you share an example project that shows how unit tests should be if we use a commercial package within the module? br
