There are xml encoding issues here: https://dev.azure.com/sgx-lkl/sgx-lkl/_build/results?buildId=1246&view=results

basic network test gets wikipedia.org and returned html is output to console which has strange characters in it.

This causes warning in pipeline runs and need to be fixed. Not outputting fetched HTML can be a solution? cc @letmaik @prp @jxyang @paulcallen

during the triage meeting, we agreed that @hukoyu's not outputting fetched HTML is a good solution as output isn't needed for the test.
