bash echo is doing commands and not adding what I need

I need to create a new file name test.sh.
I need to write those lines with echo or somethings else but cant open new file manually and write it.
That is, I have to write down some things in the bash such a way that the following file is created:

TEST_VALUE=$1
if [[cat data | grep $TEST_VALUE]]; then
exit 1
fi
exit 0

But, when I do that by echo the result is:

TEST_VALUE=
if [[]]; then
    exit 1
fi
exit 0

I need the file as I write it with $1 and not the argument and with the grep.
I tried to grep each row but it is doing the command and not copied it as I want.
How do I do it?
Thank You

>Solution :

echo 'TEST_VALUE=$1 
if [[cat data | grep $TEST_VALUE]]; then
exit 1
fi
exit 0' > test.sh

You need to use quotes, in any other case your command will be executed.
