How to search and replace a string while preserving variable part of the string in vim

Question

I want to search and replace a string in vim with preserving the variable part of string. for example:

StringA("variable1")
StringA("variable2")
StringA("variable3")
StringA("variable4")

replace this with:

StringA("variable1", new_constant_string)
StringA("variable2", new_constant_string)
StringA("variable3", new_constant_string)
StringA("variable4", new_constant_string)

What i want to do is search for

s/StringA(*)

and replace it with

        s/StringA(*)/StringA(*, new_constant_string)

where (*= variable1,variable2,variable3,variable4 and is preserved)

Do you want to preserve the double quotes or not?

You can also filter the lines using g and then apply s

:g/StringA(/s/)$/, new_constant_string)/

:g/StringA(/ all lines containing StringA(
s/)$/, new_constant_string)/ substitute ) at end of line with , new_constant_string)
- remove $ is there can be characters after ) in the line

Another method:

:%s/StringA(".\{-}"/&, new_constant_string
