from xapian_db_spec.rb:

First it removes the file if it exists:


 12     FileUtils.rm_rf tmp_dir if File.exists?(tmp_dir)

Then it creates the file in /tmp if on file database is selected

 22     it "should make an on-disk database when given a :dir option" do
 23       xdb = XapianDb.new(:dir => tmp_dir, :create => true)
 24       xdb.rw

34   it "should lazily create the on-disk database when rw is used" do
 35     xdb = XapianDb.new(:dir => tmp_dir, :create => true)
 36     File.exists?(tmp_dir).should be_false
 37     xdb.rw
 38     File.exists?(tmp_dir).should be_true
