I saw that taps developers using this package `

import tap_tester.connections as connections
import tap_tester.menagerie   as menagerie
import tap_tester.runner      as runner

where can I find 

tap_tester

package?

@meir.shamay Unfortunately, Stitch hasn't open sourced 

tap_tester

. This recently came up on the Singer Slack workspace as well: https://singer-io.slack.com/archives/C2TGFCZEV/p1599077499069400, https://singer-io.slack.com/archives/C016CTU1ESZ/p1599076357005100

Do you have some other tests utils that I can use?

@meir.shamay I'm not aware of any public ones, but the people in the Singer Slack workspace may have some more suggestions. I think it'd be great if we (or the greater Singer community) could build our own open source testing framework at some point!
