When using pipe, how to fail test when the stream writing process fails?

[velle]

I have rewritten my test a bit, as below, to focus on the essentials for this question.

@test "mytest" {
cat
sql/load_spatialite.sql
sql/gpkgCreateBaseTables.sql
sql/gpkgInsertEpsgSRID25832.sql
| sqlite3 test.gpkg
./validate_gpkg.py test.gpkg
}

If one of the files do not exist, then cat exits with exit code 1. But because I pipe stdout to another process, the exit status of that command is 0. So the test passes even though a file was not found.

Is there anything one can do to make the test fail, if the the pipe writing process (in this case cat) fails?

Try set -o pipefail

Perfect, thanks :)
