Test: argument expected

The following example prompts are passed into the shell script.
Code:
$1 = /tmp/dir/
$2 = varies (test.txt, test1.txt, test2.txt...)
$3 = test_YYYYMMDD.txt

---------------------------------------------------------------------------
Code:
#!/bin/sh
cd $1

if [ $2 = "test.txt" ]; then
        if [ -e $2 ]; then
                echo $2 $3
                echo 'File already exists'
                mv $2 $3
                exit 1
        else
                echo 'File not found'
                exit 0
        fi
else
        if [ -s $2 ]; then
                echo $2 $3
                echo 'File already exists and is not empty'
                mv $2 $3
                exit 1
        else
                echo 'File not found or is empty'
                exit 0
        fi
fi

------------------------------------------------------------
If say the file is test1.txt then it finishes correctly with no errors. However, if it is test.txt then I can see it evaluate the -e part because I turned on debugging. What I see is:
+ [ test.txt = test.txt ]
+ [ -e test.txt ]
scriptpathandscriptname: test: argument expected

Does anyone have any information as to why I am getting the argument expected? Any information would be helpful.

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
