Bash script capturing output to terminal

I want to capture into my bash script (in a variable) the output of some command that prints its output to terminal. I have tried the following: 

TEST_OUT=`the_command ARG1`   #Nope

#Putting the line "the_command ARG1" into a separate script, testing2.sh,

TEST_OUT=$(./testing2.sh)   #Nope

testing2.sh
TEST_OUT=$?  #Nope

I am 100% sure that when I run... 

> the_command ARG1

...in a terminal, it prints to the terminal exactly the information I want to capture.

Thank you for any help!

If the output is being sent to stderr, you'll need to redirect that to stdout before it can be capture in your var. Try: 

TEST_OUT=$(the_command ARG1 2>&1)
