use variables
Pulling common elements into variables will make those things easier to follow and change later.
BRANCH_TEST="test"
BRANCH_PASSED="test-passed"
git status
git reset --hard
git pull origin $BRANCH_TEST
git checkout origin/$BRANCH_TEST
git pull origin $BRANCH_PASSED
git checkout origin/$BRANCH_PASSED
git merge origin/$BRANCH_TEST
git push origin HEAD:$BRANCH_PASSED
error checking
Is there any chance one of the steps will fail? You could check the return value of each step or just set -e to get bash to exit on any command having an error.
There is also bash strict mode which builds on set -e with some other things to make coding in the shell less surprising.
documentation
It would be a good idea to explain what the intent of the code is.
shebang
Presumably this is a bash script. It would be good to make it clear by putting
#!/bin/bash
as the first line.
