Return chances of false positive file path semantics
If the type of an variable can't be determined, guess at string, but lower the confidence level
Error Message Extraction:
Capture error messages from die/croak/confess
Use them to understand what makes input invalid die "Age must be positive" if $age <= 0;
Store that a negative/zero age is invalid
Use test of scalar(@_) to check for number of optional/mandatory args
Throw a float at a routine that only takes integers - it should error
Added example extraction
Parse POD for example calls and extract valid parameter combinations =head2 SYNOPSIS my $obj = Module->new(foo => 'bar', count => 5);
Store these as known-good test values
Corpus bool testing now uses ok rather than is
Ensure new doesn't refer to other packages
Set the isa property in the new function
0.23 Wed Dec 24 10:48:03 EST 2025
Fix https://www.cpantesters.org/cpan/report/079dba46-d92f-11f0-9642-dde56d8775ea
Don't give false negative that memberof isn't known
SchemaExtractor output files now end in .yml not .yaml
Ensure rand_str isn't called when memberof is set
When test_empty is set, do the right thing for memberof
0.22 Sun Dec 21 20:59:58 EST 2025
Added better API to generate
Added parameter relationship detection (mutually exclusive, required groups, conditional requirements, dependencies, value constraints)
Improved Object Detection
Detect factory methods that return instances
Recognize singleton patterns
Identify when constructor needs specific parameters
Handle inheritance (when parent class new() is needed)
Better Default Value Extraction
$param = $param || 'default_value'
$param //= 'default_value'
$param = defined $param ? $param : 'default'
Expanded _detect_list_context to
Better distinguish scalar vs list returns
Detect void context methods (those that modify state)
Recognize chaining patterns more reliably Identify error return conventions (undef on failure, etc.)
Add confidence scoring transparency, explain WHY confidence is what it is:
_analysis: confidence_factors:
- "POD documentation present (+30)"
- "Type validation in code (+20)"
- "No constraint information (-10)"
Add support for:
- Signatures (sub foo($x, $y = 5) { })
- Postfix dereferencing ($array->@*)
- Subroutine attributes (sub foo :Returns(Int) { })
- Field declarations (Perl 5.38+)
Added a new section to generated YAML:
yamltest_hints: boundary_values: [0, 1, 100, 255]
detected from code invalid_inputs: ['', undef, -1]
from validation checks equivalence_classes: []
0.21 Sun Dec 14 08:07:09 EST 2025
Schemaextractor: don't put the package name as the argument
Validate config settings better
Fix max string testing with non-ASCII characters
Changed rand_str to be a unified generator that randomly produces codepoint strings,
grapheme clusters, ZWJ emoji sequences, or aggressive Unicode fuzz strings
Schemaextractor: Added advanced type detection for DateTime objects, file handles, coderefs, and enum validation patterns
Added enum as a synonym of memberof
Added tests for unix_timestamp semantic type
0.20 Fri Dec 5 07:53:43 EST 2025
Added the --version flag to fuzz-harness-generator
Ensure the max value of string is honoured better
Fix array context detection to only match return statements
Improve chances of detecting a boolean output
Make the list context detection more specific
0.19 Wed Nov 26 07:50:22 EST 2025
Fixed the loop iterating over mandatory args
Ensure mandatory_args honours matches
0.18 Tue Nov 25 11:58:12 EST 2025
Removed one place sending '' if test_empty was disabled
Don't send long strings if matches is set
Fixed handling of position code with more than argument
Renamed the sample module
0.17 Tue Nov 25 10:24:36 EST 2025
Improved TEST_VERBOSE output for Corpus tests
Make the strings more random
Added test_non_ascii (default 1) to the configuration matrix
Removed all legacy conf code
Re-ordered the POD
Don't give 42 if max < 42
Added App::Test::Generator::SchemaExtractor
0.16 Thu Nov 20 08:38:17 EST 2025
Use Data::Random::String to generate the string
Use Data::Random::Structure to generate references to hashes and arrays
Remove legacy support for Perl config files
Handle the case when all inputs should cause a die(),
allows App::Test::Generator to sanity test itself
If something is expected to die, don't look at its return code
More boolean edge cases
Don't pass _NAME to validate_strict
When a routine dies, it shouldn't return anything
Begin to use semantic types
Use Test::LectroTest to create more tests
Added custom properties
Separated the Template into its own class to ease maintenance
Use reusable functions to generate cases
Rand_set returns and array, so look at the first element
0.15 Tue Nov 11 19:30:18 EST 2025
Documented how to Fuzz test a CPAN module
populate_positions - don't attempt to deref a scalar
carp when undef is a corpus test case, but test_undefs is not set
Improved handling of cases array for WARNS and DIES
Improved handling of validating position settings in config files
Croak if the schema_file can't be opened
Close stdin and use /dev/null
Fixed logic in testing short strings when min >= 2
0.14 Fri Nov 7 20:26:32 EST 2025
Fixed logic when neither memberof nor notmemberof were defined,
which could cause an empty notmemberof array to be created
Transform: better number of items for arrayrefs
