Bash, grep between two lines with specified string in a file having multiple set of such lines

Question

Example:

a43
test1
abc
cvb
bnm
test2
kfo
a43
test1
abc
cvb
bnm
test2
kfo
a43
test1
abc
cvb
bnm
test2
kfo

i need to find all lines between first occurence of test1 and test2. Below grep command does not work for this :

grep -A100000 test1 file.txt | grep -B100000 test2 > new.txt

can you please let me know if any modifications are needed to do the same?

This awk should do the job:

awk '/test1/{p=1} p; /test2/{exit}' file
test1
abc
cvb
bnm
test2
