Backport
This PR is auto-generated from #12853 to be assessed for backporting due to the inclusion of the label backport/1.3.x.
The below text is copied from the body of the original PR.
A testing cleanup.
This pull request replaces
ioutil.TempDir
witht.TempDir
. We can use theT.TempDir
function from thetesting
package to create temporary directory. The directory created byT.TempDir
is automatically removed when the test and all its subtests complete.This saves us at least 2 lines (error check, and cleanup) on every instance, or in some cases adds cleanup that we forgot.
