# This script generates a bash script to run a certain set of backend tests
# using the unified backend test executable. It take two positional arguments:
# 1: The file location to write the generated script
# 2: The test filter pattern that describes which tests to run (following gtest's
#    --gtest_filter)
# This script is used by the build system and is not intended to be run directly.

# Running a gtest executable using the -gtest_filter flag produces a JUnitXML that
# contains all the tests whether they ran or not. The tests that ran are populated
# normally. The tests that didn't run have status="notrun". This is a problem for the
# unified binary, because every JUnitXML would contain every test, with a large portion
# of them marked as notrun. Various consumers of JUnitXML (such as Jenkins) may not
# understand this distinction, so it is useful to prune the notrun entries. The
# junitxml_prune_notrun.py walks through the JUnitXML file and drops the entries that
# did not run, producing a new JUnitXML file of the same name.
