Constructor Details

#initialize(source_text = nil) ⇒ Example

Creates a new Example object and, if source_text is provided, populates the object.

Examples:

Example.new
Example.new("|param_1|param_2|\n|value_1|value_2|")

Parameters:

  • source_text (String) (defaults to: nil) —

    The Gherkin text that will be used to populate the model

Raises:

  • (ArgumentError) —

    If source_text is not a String

Instance Method Details

#add_row(row) ⇒ Object

Adds a row to the example table. The row can be given as a Hash of parameters and their corresponding values or as an Array of values which will be assigned in order.

Examples:

example.add_row({'param1' => 'value1', 'param2' => 'value2'})
example.add_row({param1: 'value1', param2: 'value2'})
example.add_row(['value1', 'value2'])

Parameters:

  • row (Hash, Array<String>) —

    The the cell values to use for the added row

Raises:

  • (ArgumentError) —

    If row is not a Hash or Array

  • (Exception) —

    If the model has no initial parameter row

def add_row(row)
  raise('Cannot add a row. No parameters have been set.') if rows.empty?

  # A quick 'deep clone' so that the input isn't modified
  row = Marshal.load(Marshal.dump(row))

  values = if row.is_a?(Array)
             row
           elsif row.is_a?(Hash)
             # There is no guarantee that the user built up their hash with the keys in the same order as
             # the parameter row and so the values have to be ordered by us. Additionally, the hash needs
             # to have string keys in order for #order_row_values to work
             ordered_row_values(stringify_keys(row))
           else
             raise(ArgumentError, "Can only add row from a Hash or an Array but received #{row.class}")
           end

  @rows << Row.new("|#{values.join('|')}|")
end

#argument_rows ⇒ Array<Row>

Returns the Row models associated with the argument rows in the example table

Examples:

example.argument_rows

Returns:

  • (Array<Row>) —

    The argument row models

# File 'lib/cuke_modeler/models/example.rb', line 111

def argument_rows
  rows[1..rows.count] || []
end

#children ⇒ Array<Row, Tag>

Returns the model objects that are children of this model. For an Example model, these would be any associated Row or Tag models.

Examples:

example.children

Returns:

  • (Array<Row, Tag>) —

    A collection of child models

# File 'lib/cuke_modeler/models/example.rb', line 143

def children
  rows + tags
end

#inspect(verbose: false) ⇒ String

See ‘Object#inspect`. Returns some basic information about the object, including its class, object ID, and its most meaningful attribute. For an Example model, this will be the name of the example. If verbose is true, provides default Ruby inspection behavior instead.

Examples:

example.inspect
example.inspect(verbose: true)

Parameters:

  • verbose (Boolean) (defaults to: false) —

    Whether or not to return the full details of the object. Defaults to false.

Returns:

  • (String) —

    A string representation of this model

# File 'lib/cuke_modeler/models/example.rb', line 185

def inspect(verbose: false)
  return super if verbose

  "#{super.chop} @name: #{name.inspect}>"
end

#parameter_row ⇒ Row?

Returns the Row model associated with the parameter row in the example table

Examples:

example.parameter_row

Returns:

  • (Row, nil) —

    The parameter row model

123
124
 
# File 'lib/cuke_modeler/models/example.rb', line 122

def parameter_row
  rows.first
end

#parameters ⇒ Array<String>

Returns the parameters of the example table

Examples:

example.parameters #=> ['param_1', 'param_2']

Returns:

  • (Array<String>) —

    The parameters

133
134
 
# File 'lib/cuke_modeler/models/example.rb', line 132

def parameters
  parameter_row ? parameter_row.cells.map(&:value) : []
end

#remove_row(row) ⇒ Object

Removes a row from the example table. The row can be given as a Hash of parameters and their corresponding values or as an Array of values which will be assigned in order.

Examples:

example.remove_row({'param1' => 'value1', 'param2' => 'value2'})
example.remove_row(['value1', 'value2'])

Parameters:

  • row (Hash, Array<String>) —

    The the cell values to use for the added row

Raises:

  • (ArgumentError) —

    If row is not a Hash or Array

           end

  location = index_for_values(values.map(&:to_s).map(&:strip))
  @rows.delete_at(location + 1) if location
end

#to_s ⇒ String

Returns a string representation of this model. For an Example model, this will be Gherkin text that is equivalent to the example being modeled.

Examples:

example.to_s

Returns:

  • (String) —

    A string representation of this model
