NAME

TestFuncs - routines used by several tests

SYNOPSIS

    use Test::Structs qw(is_same is_numeric);

    is_same($ref1, $ref2, 'test name');
    is_same($ref1, $ref2, 'test name', 0.1);
    is_numeric($scalar);

DESCRIPTION

Used in the same was as Test::Simple and Test::More, this adds my home rolled tests.

is_same( ref1, ref2 [, test_name [, accuracy]] )

ref1 and ref2 can be references to arrays or hashes. The structures are compared item by item, including any sub-arrays or sub-hashes. If accuracy is specified, numbers may differ by this amount before the test fails.

TODO: Doesn't handle blessed references Reporting of deep errors not really tested

from_csv( filename )

Reads CSV file returning data as an array ref.

csv_to_sample( filename )

Reads data from the specified CSV file and returns a hash with the same structure as Finance::Shares::Sample data, i.e. open, high, low, close, volume and lx sub-hashes.

array_to_sample( arrayref )

Given an array structured like a CSV file, it returns a hash with the same structure as Finance::Shares::Sample data, i.e. open, high, low, close, volume and lx sub-hashes and dates array.

sample_to_csv( sample, file )

Writes out Finance::Shares::Sample data so that it can be read by from_csv.

show_lines( sample )

Prints the ids of all known lines. Returns a string which may be displayed with e.g. warn.

show( [values...], [names...] )

Calls Data::Dumper on values passed. Returns a string which may be displayed with e.g. warn.

show_deep( var [, min [, sep]] )

Recursively dumps hash or array refs, returning a string which may be displayed with e.g. warn.

var

The scalar variable to be printed.

min

A limit to the depth printed out.

sep

String used to seperate entries (between pairs, not within them).

check_filesize( filename, size )

This must be invoked from ../t as it uses a file 't/filesizes' to store the size each file should be.
