I’m writing an integration test and want to know the best way to pipe to STDIN
.
The closest I’ve gotten is print(STDIN, "blah")
, but this still required me to press enter.
What’s the best way to accomplish this?
I know redirect_stdin()
exists, but the docs and googlable posts don’t really say much.
Not necessarily the best solution, but did you try adding \n
to the print statement?
That didn’t work.
The problem is I have to type enter before anything gets added to the buffer
edit: for reference, here’s the thing that’s waiting for input
function user_input(prompt)
print(prompt)
answer = readline()
chomp(answer)
end
Is this something like what you want?
let filename = tempname()
open(filename,"w") do f
println(f,"my answer!")
end
ret = open(filename) do f
redirect_stdin(f) do
user_input("what do you say?")
end
end
println("\nresult was: ",ret) # for testing the test
rm(filename)
contains(ret, "my answer!") || error("test failed!")
end
(cribbed from the Julia test suite)
