Contents of STDOUT is not printed in the report output

Some of my steps print to STDOUT with the following:
e.g. fwrite(STDOUT, "$reponse");

However these are not logged in the report, only statements which use echo/print

Why are you doing this? You are asking the software to print this data somewhere else. Why do you expect that in the report now? Why dont you can use echo?
