~ is a shell globbing operator, it has no meaning outside /bin/sh.

Use ENV['HOME'] + "/ruby/sample/testFile" or, um, I'm sure I saw a
function to expand shell globs somewhere.. maybe Dir#glob or something.

You're opening a file here but then not doing anything with it; where is
testFile from?

you want:

File.open(ENV['HOME'] + "/ruby/sample/testFile", "r") do |testFile|
..
end
