So I instantiated the class but it didn't work either
terminal :
 

unitTests.testSqlAgateInscription begins ...

TestMyMethod() begins ...

LogStateStatus:0:TestMyMethod:ERREUR #5002: Erreur Cache: <INVALID OREF>zTestMyMethod+4^unitTests.testSqlInscription.1 <<==== **FAILED**

unitTests:unitTests.testSqlInscription:TestMyMethod:

TestMyMethod failed

unitTests.testSqlInscription failed

unitTests failed
The code looks like that :
 

Class unitTests.testSqlInscription Extends %UnitTest.TestCase

{

Method TestMyMethod()

{

 set myObject = ##class(Package.BO.sqlInscription).%New()

 set myRequest = ##class(Package.Msg.getSomeDataFromDataBaseRequest).%New()

 set myRequest.somePropertyaboutEmail = "test@mail.com"

 do $$$AssertEquals(myObject.getSomeDataFromDataBase(myRequest),1953642, "Test MyMethod()=1953642")

}
}
I'm really out of ideas here to set up a basic unit test. Any hint is much welcome. 
Please and thank you. 
 

Ok i'll get going on instanciating the class first and see what it does.
The classMethod present a problem with the adapter method that i call.  
Thanks for your input.

that's great intel, thank you very much !

That's about it (not exactly, but close enough, the check on server B is done from another server where Ensemble is running, so same difference i think) 
I'll give it a shot.
Thank you, Stefan ! 
PS:
Not sure abou the long connection thingy you mentionned in the comment below, i don't think it's relevant, but i'll keep it in mind if i run into troubles. It is currently set to -1 (never disconnected) so this might gets me in trouble eventually.
Thanks for the heads up. 
 

Hi Stefan, 
The whole thing looks like this:
Files are dropped on server A:/origin_folder by some piece of software. The passthrough service is listening to this server A location and get triggered whenever the files are dropped. The files are then move to server B:/reception_folder with the passthrough operation. 
I then want Ensemble to check on server B:/reception_folder that the files are indeed present. 
If the transfer didn't go well, i need an email to be sent to some recipients. 
The BP in my design is here to call the passthrough BO, and handle the potentials problems. 
Does that make sense ?
