pherkin(1) Execute tests written using Test::BDD::Cucumber


version 0.50


pherkin some/path/features/


"pherkin" accepts a single argument of a directory name, defaulting to "./features/" if none is specified. This directory is searched for feature files (any file matching "*.feature") and step definition files (any file matching "*"). The step definitions are loaded, and then the features executed.

Steps that pass are printed in green, those that fail in red, and those for which there is no step definition - or that are skipped as the result of a previous failure - as yellow.

"pherkin" will exit with a non-zero status if (and only if) the overall result is considered to be failing.


Controlling @INC

 -l, --lib              Add 'lib' to @INC
 -b, --blib             Add 'blib/lib' and 'blib/arch' to @INC
 -I [dir]               Add given directory to @INC

Output formatting

 -o, --output           Output harness. Defaults to 'TermColor'. See 'Outputs'
 -c, --theme            Theme for 'TermColor'. `light` or `dark` (default)

Extra Steps

  -s, --steps [path]    Include an extra step file, or directory of step files
                        (as identified by *; multiple use accepted)

Tag specifications

 -t, --tags @tag        Run scenarios tagged with '@tag'
 -t, --tags @tag1,@tag2 Run scenarios tagged with '@tag1' and '@tag2'
 -t, --tags [email protected]       Run scenarios tagged without '@tag'

Configuration profiles (see CONFIGURATION PROFILES below/`man pherkin`)

 -g, --config [path]    A YAML file containing configuration profiles
 -p, --profile [name]   Name of the profile to load from the above config file.
                        Defaults to `default`
 --debug-profile        Shows information about which profile was loaded and how
                        and then terminates


 -e Extension::Module   Load an extension. You can place a string in brackets at
                        the end of the module name which will be eval'd and
                        passed to new() for the extension.


 -h, -?, --help         Print usage information.
 --i18n LANG            List keywords for a particular language.
                        '--i18n help' lists all languages available.


"pherkin" can output using any of the "Test::BDD::Cucumber::Harness" output modules. Test::BDD::Cucumber::TermColor is the default, but Test::BDD::Cucumber::TestBuilder is also a reasonable option:

  pherkin -o TermColor some/path/feature   # The default
  pherkin -o TestBuilder some/path/feature # Test::Builder-type text output


You can specify sets of command line options using a YAML configuration file with named profiles in it, and the "-g, --config" and "-p, --profile" command line options.

If you don't specify a config file, the following paths are searched (in order) for one:

 (contents of $ENV{'PHERKIN_CONFIG'})

The contents of each profile is merged in as if you'd specified it on the command line. "default" is used if you didn't specify one. For example:

     - foo/steps
     - ~/steps
   output: TermColor
     - tag1,tag2

is equivalent to:

  --steps foo/steps --steps ~/steps --output TermColor --tags tag1,tag2

If you specify both command-line options, and options in a configuration file, then the command-line ones override single-value items, and are placed at the end of multi-item ones.

If you specify "--debug-profile" then information showing which profile is loaded and how is printed to STDOUT, and then `pherkin` terminates.


Extensions named in the "extensions" section of the configuration will be loaded with the configuration from the configuration file:

      # include location where extensions reside on disk
      - t/lib
      # extension with configuration
          key1: value1
          key2: value2
      # extension without configuration

Notice that contrary to all other configuration parameters, the names of the extensions are not prefixed with a dash (i.e. '- t/lib' vs 'Test::CucumberPush').

The example above is the equivalent of

  use Test::CucumberPush;
  use Test::CucumberPop;
  Test::CucumberPush->new({ 'key1' => 'value1', 'key2' => 'value2' });
