Shell Script to count different extention of each file

Our application we have lot of files.
each file has it's  3-different extention.

for example.....

testfile.ext1
testfile.ext2
testfile.ext2

report.ext1
report.ext2



I want to have shell script, which can test, how many extentions had for each file.
so that, I can easily track missting files.

In otherwords .... , from the above example of files which were listed, I want to have out put like below.

OutPut
==================
testfile ----- has count ---- 3
report  ----- has count -----2

please advice
