Commands to revert specific tests for protobuf fields

[klingbolt]

#361 removes several tests from the integration_test directory because the protobuf field is not yet implemented in Burrito. If these files are deemed useful later without changes to the protobuf field, the following code can be used. Single test cases can be called by adding the test name.

git rm -r xml_converter/integration_tests/test_cases/{$TEST_NAME}
git checkout 0418c72d19ff5668ada98d39e8d23cd2ef0ae9bf xml_converter/integration_tests/test_cases/{$TEST_NAME}
git commit -m "reverting directory {$TEST_NAME}"
