No, it's totally broken. $(pwd)/$test is nonsensical. The code right
above your change guarantees that $test is an absolute path, either
because the user gave us an absolute $root or because it has been
prepended with $TEST_DIRECTORY (which itself comes from $(pwd)).

So the change you want is HOME=$test. But note that the code looks like
this then:

  HOME=$test
  export HOME
  test_create_repo "$test"
  cd -P "$test"

meaning that test_create_repo sees a non-existent HOME. I don't
think that matters, but if it did, you could do:

  HOME=$TEST_DIRECTORY
  export HOME
  test_create_repo "$test"
  cd -P "$test"
  HOME=$test
