# Read a test definition which exercises curl's --libcurl option.
|
|
# Generate either compilable source code for a new test tool,
|
|
# or a new test definition which runs the tool and expects the
|
|
# same output.
|
|
# This should verify that the --libcurl code really does perform
|
|
# the same actions as the original curl invocation.
|
|
#-----------------------------------------------------------------------
|
|
# The output of curl's --libcurl option differs in several ways from
|
|
# the code needed to integrate with the test tool environment:
|
|
# - #include "test.h"
|
|
# - no call of curl_global_init & curl_global_cleanup
|
|
# - main() function vs. test() function
|
|
# - no checking of curl_easy_setopt calls vs. test_setopt wrapper
|
|
# - handling of stdout
|
|
# - variable names ret & hnd vs. res & curl
|
|
# - URL as literal string vs. passed as argument
|
