Command Line Options

Table of Contents

Driver Configuration

You can customize which driver your tests use via the --driver command line flag. The default driver is chrome. For example:

  • --driver=phantomjs
  • --driver=firefox

Error Formatting

You can customize the format in which your errors are formatted via the --error_formatter command line flag. The default format is five lines of the stack trace with a blue first line. To customize the formatter see below

my_formatter.js should export a method like the following

module.exports = function(err) {
  console.log("my custom error formatter", err.stack);
}

Tags

To only run selected features include --tags=@myTag and insert @myTag directly before the intended feature(s).

Prevent Browser Reload

To speed up testing, an optional --preventReload flag can be passed to prevent the web driver from restarting after each feature:

./node_modules/.bin/pioneer --preventReload=true

CoffeeScript Step Scaffold

To have cucumber generate the step scaffold automatically in CoffeeScript, use the optional --coffee line flag.

./node_modules/.bin/pioneer --coffee

Configuration File Path

Pioneer configuration options can be declared in the form of a JSON file. To declare the path to this file use the optional --configPath= flag. Addtional information on the format of this file can be found here

./node_modules/.bin/pioneer --configPath=myConfig.json

Scaffold Creation

Pioneer can generate a scaffold for your first tests automatically using the optional --scaffold command line flag. This generates a tests/ directory, with features/, steps/ and widgets/. It creates simple.feature and simple.js files that include your first Pioneer test! It also creates a pioneer.json file in your current working directory. This config file automatically includes the created feature files, and the following information:

{
  "feature": "tests/features",
  "require": [
    "tests/steps",
    "tests/widgets"
  ],
  "format": "pioneerformat.js",
  "driver": "chrome",
  "error_formatter": "errorformat.js",
  "preventReload": false,
  "coffee": false
}

Verbosity

You can show some extra information about the test run by setting the --verbose flag. This can be used to override the value in the config file. You will need to use --verbose=false to turn off verbosity that has been set in the config file.

Version

You can display the current version of Pioneer that you are using by passing the optional --version or -v command line flag.
