Test::Base::Filter - Default Filter Class for Test::Base
package MyTestSuite; use Test::Base -Base; ... reusable testing code ... package MyTestSuite::Filter; use Test::Base::Filter -Base; sub my_filter1 { ... }
Filters are the key to writing effective data driven tests with Test::Base. Test::Base::Filter is a class containing a large default set of generic filters. You can easily subclass it to add/override functionality.
This is a list of the default stock filters (in alphabetic order):
append
list => list
Append a string to each element of a list.
--- numbers lines chomp append=-#\n join one two three
array
list => scalar
Turn a list of values into an anonymous array reference.
base64_decode
scalar => scalar
Decode base64 data. Useful for binary tests.
base64_encode
Encode base64 data. Useful for binary tests.
chomp
Remove the final newline from each string value in a list.
chop
Remove the final char from each string value in a list.
dumper
scalar => list
Take a data structure (presumably from another filter like eval) and use Data::Dumper to dump it in a canonical fashion.
escape
Unescape all backslash escaped chars.
eval
Run Perl's eval command against the data and use the returned value as the data.
eval_all
Run Perl's eval command against the data and return a list of 4 values:
1) The return value 2) The error in $@ 3) Captured STDOUT 4) Captured STDERR
eval_stderr
Run Perl's eval command against the data and return the captured STDERR.
eval_stdout
Run Perl's eval command against the data and return the captured STDOUT.
exec_perl_stdout
Input Perl code is written to a temp file and run. STDOUT is captured and returned.
flatten
Takes a hash or array ref and flattens it to a list.
get_url
The text is chomped and considered to be a url. Then LWP::Simple::get is used to fetch the contents of the url.
hash
Turn a list of key/value pairs into an anonymous hash reference.
head[=number]
Takes a list and returns a number of the elements from the front of it. The default number is one.
join
Join a list of strings into a scalar.
Join
Join the list of strings inside a list of array refs and return the strings in place of the array refs.
lines
Break the data into an anonymous array of lines. Each line (except possibly the last one if the chomp filter came first) will have a newline at the end.
norm
Normalize the data. Change non-Unix line endings to Unix line endings.
prepend=string
Prepend a string onto each of a list of strings.
read_file
Read the file named by the current content and return the file's content.
regexp[=xism]
The regexp filter will turn your data section into a regular expression object. You can pass in extra flags after an equals sign.
regexp
If the text contains more than one line and no flags are specified, then the 'xism' flags are assumed.
reverse
Reverse the elements of a list.
Reverse
Reverse the list of strings inside a list of array refs.
slice=x[,y]
Returns the element number x through element number y of a list.
sort
Sorts the elements of a list in character sort order.
Sort
Sort the list of strings inside a list of array refs.
split[=string|pattern]
Split a string in into a list. Takes a optional string or regexp as a parameter. Defaults to s+. Same as Perl split.
split
Split[=string|pattern]
Split each of a list of strings and turn them into array refs.
strict
Prepend the string:
use strict; use warnings;
to the block's text.
tail[=number]
Return a number of elements from the end of a list. The default number is one.
trim
Remove extra blank lines from the beginning and end of the data. This allows you to visually separate your test data with blank lines.
unchomp
Add a newline to each string value in a list.
write_file[=filename]
Write the content of the section to the named file. Return the filename.
yaml
Apply the YAML::Load function to the data block and use the resultant structure. Requires YAML.pm.
