Outside of the script, all the script's io is piped to 'tee' and so it is only done the one time.
Inside the script you would have to pipe all your commands that might produce output to 'tee' to get your desired result.
Basically in the script you wrote, only the 'exec' command was piped to 'tee' and as a result only it's ouput was "written" to test.log, and therefore you have an empty file.
If you had piped 'pwd' to 'tee' instead you would have gotten output in your log file.

TEE(1) User Commands TEE(1)
NAME
tee - read from standard input and write to standard output and files
SYNOPSIS
tee [OPTION]... [FILE]...
DESCRIPTION
Copy standard input to each FILE, and also to standard output.
-a, --append
append to the given FILEs, do not overwrite
-i, --ignore-interrupts
ignore interrupt signals
-p diagnose errors writing to non pipes
--output-error[=MODE]
set behavior on write error. See MODE below
--help display this help and exit
--version
output version information and exit
MODE determines behavior with write errors on the outputs:
'warn' diagnose errors writing to any output
'warn-nopipe'
diagnose errors writing to any output not a pipe
'exit' exit on error writing to any output
'exit-nopipe'
exit on error writing to any output not a pipe
The default MODE for the -p option is 'warn-nopipe'. The default operation when --output-error is not specified, is to exit immediately on
error writing to a pipe, and diagnose errors writing to non pipe outputs.
