How to change name of the file with first line of the file which has some unwanted text in it?

I have a log file, which i have divided into 14 files using csplit, the file looks like below

Code:
test-000000
test-000001 #and so on until 14

now I want all the 14 files generated to be renamed as the some part of test in first line of the file how can i eliminate the unwanted text?

sample first line of the file looks like, all the files have similar format

Code:
0-00:01:01.412 <main>:[UNIT]:[info]:  Test: SCHEDULE_REQUEST_TestCase ...

I want to rename the file as SCHEDULE_REQUEST_TestCase.log
I know that mv command can be used to rename the file, and read or head can be used to read the first line of the file, but i want to remove the text before SCHEDULE and dots after TestCase.

This is what i have at the moment

Code:
line="$(head -n 1 test-000000)"
mv test-000000 ${line}.log

I want to perform this for all the files i have generated i don't really get how to do that and eliminate the unwanted text from the first line? I guess sed or awk can be used to eliminate the text I have started shell scripting like five days ago any help would be greatly appreciated.

NAME
Test::Moose - Test functions for Moose specific features VERSION
version 2.0603 SYNOPSIS
use Test::More plan => 1; use Test::Moose; meta_ok($class_or_obj, "... Foo has a ->meta"); does_ok($class_or_obj, $role, "... Foo does the Baz role"); has_attribute_ok($class_or_obj, $attr_name, "... Foo has the 'bar' attribute"); DESCRIPTION
This module provides some useful test functions for Moose based classes. It is an experimental first release, so comments and suggestions are very welcome. EXPORTED FUNCTIONS
meta_ok ($class_or_object) Tests if a class or object has a metaclass. does_ok ($class_or_object, $role, ?$message) Tests if a class or object does a certain role, similar to what "isa_ok" does for the "isa" method. has_attribute_ok($class_or_object, $attr_name, ?$message) Tests if a class or object has a certain attribute, similar to what "can_ok" does for the methods. with_immutable { CODE } @class_names Runs CODE (which should contain normal tests) twice, and make each class in @class_names immutable in between the two runs. TODO
Convert the Moose test suite to use this module. Here is a list of possible functions to write immutability predicates anon-class predicates discovering original method from modified method attribute metaclass predicates (attribute_isa?) SEE ALSO
