maven - Passing dataProvider parameter inside testng method -

i have 2 @dataproviders:

@dataprovider(name = "smallnumbers") @dataprovider(name = "bignumbers") 

variables in pom.xml

<systempropertyvariables> <datap>${dataprovider}</datap> </systempropertyvariables> 

accesing parameter:

string sizenumbers = system.getproperty("datap"); 

and test:

@test(dataprovider=sizenumbers)  

dataprovider in test method have be: constant expression idea how pass variable inside @test(dataprovider= ?

you cant this. possible pass dataprovider directly method. why choose way inject data dataprovider? show bit more code architecture cause that's strange.

edit:

you can check way:

@dataprovider(name = "dp") public static object[][] datainject(){   return new object[][]{             {sizenumbers}   }; }  

and inside "dp" can make validation ex. "isnull" etc.

then in test

@test(dataprovider = "dp", dataproviderclass = xyz.class) public void testfirst(string input){ //... }
