Read content of file and put particular portion of content in separate files using bash

Question

I would like to get specific file contains from single file and put into separate files via bash. I have tried getting test1 file contain using below code and able to get it but i'm failed when getting everything in respected files.

Tried code:

reportFile=/report.txt
test1File=/test1.txt
test2File=/test2.txt
test3File=/test3.txt

totalLineNo=`cat ${reportFile} | wc -l`
test1LineNo=`grep -n "Test1 file content :" ${reportFile} | grep -Eo '^[^:]+'`
test2LineNo=`grep -n "Test2 file content :" ${reportFile} | grep -Eo '^[^:]+'`
test3LineNo=`grep -n "Test3 file content :" ${reportFile} | grep -Eo '^[^:]+'`

exactTest1LineNo=`echo $(( ${test1LineNo} - 1 ))`
exactTest2LineNo=`echo $(( ${test2LineNo} -1 ))`
exactTest3LineNo=`echo $(( ${test3LineNo} -1 ))`

test1Content=`cat ${reportFile} | head -n ${exactTest1LineNo}`
test3Content=`cat ${reportFile} | tail -n ${exactTest3LineNo}`

echo -e "${test1Content}\r" >> ${test1File}
echo -e "${test3Content}\r" >> ${test3File}

With single awk command:

awk '/^Test[0-9] file content:/{ f=1; fn=tolower($1)".txt"; next }
     f && NF{ print > fn }!NF{ f=0 }' report.txt 

Viewing results:

$ head test[0-9].txt
==> test1.txt <==
1
2
3
4
5
6

==> test2.txt <==
7
8
9
10

==> test3.txt <==
11
12
13
14
15
