shell script - printing result to a file and command prompt simultaneously

Is there a way to simultaneously print a result to command prompt and to a file?

for example: 

    echo a >test.log

the output "a " must be written both to test.log file and command prompt simultaneously.

Use tee which reads from standard input and writes to standard output and files.
