.SH "DESCRIPTION"

The \f(CW\*(C`App::CELL::Test\*(C'\fR module provides a number of special-purpose functions for
use in \s-1CELL\s0's test suite.
.SH "EXPORTS"
.IX Header "EXPORTS"
This module exports the following routines:
    cleartmpdir
    cmp_arrays
    mktmpdir
    populate_file
    touch_files
.SH "PACKAGE VARIABLES"
.IX Header "PACKAGE VARIABLES"
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.SS "mktmpdir"
.IX Subsection "mktmpdir"
Creates the App::CELL testing directory in a temporary directory
(obtained using File::Temp) and returns the path to this directory in
the payload of a status object.
.SS "cleartmpdir"
.IX Subsection "cleartmpdir"
DESTROYs the temporary directory object (see File::Temp).
.PP
\fI_touch\fR
.IX Subsection "_touch"
.PP
Touch a file
.SS "touch_files"
.IX Subsection "touch_files"
\&\*(L"Touch\*(R" some files. Takes: directory path and list of files to \*(L"touch\*(R" in
that directory. Returns number of files successfully touched.
.SS "populate_file"
.IX Subsection "populate_file"
Takes filename (full path) and contents (as a string, potentially
containing newlines) to write to it. If the file exists, it is first
unlinked. Then the routine creates the file and populates it with
the contents. Returns true if something was written, or false if not.
.SS "cmp_arrays"
.IX Subsection "cmp_arrays"
Compare two arrays of unique elements, order doesn't matter. 
Takes: two array references
Returns: true (they have the same elements) or false (they differ).
