#!/bin/bash
# This script runs some of WarpX's standard regression tests, but
# without comparing the output to previously run simulations.
# This checks that:
# - The code compiles and runs without error
# - For some of the tests, a Python script checks that the results are
# physically correct.

# The tests can be influenced by environment variables:
# Use `export WARPX_TEST_DIM=3` or `export WARPX_TEST_DIM=2` in order to
# select only the tests that correspond to this dimension
# Use `export WARPX_TEST_ARCH=CPU` or `export WARPX_TEST_ARCH=GPU` in order
# to run the tests on CPU or GPU respectively.

# Remove contents and link to a previous test directory (intentionally two arguments)
rm -rf test_dir/* test_dir
# Create a temporary test directory
tmp_dir=$(mktemp --help >/dev/null 2>&1 && mktemp -d -t ci-XXXXXXXXXX || mktemp -d "${TMPDIR:-/tmp}"/ci-XXXXXXXXXX)
if [ $? -ne 0 ]; then
    echo "Cannot create temporary directory"
