  selected = BRANCHES.values.flatten.uniq
  branches.each do |branch|
    selected &= BRANCHES[branch] if BRANCHES.key? branch
  end

  raise ArgumentError, 'Filters do not match any sciences' if selected.empty?

Faker::Science.tool #=> "Quantum Spectrophotometer"
Faker::Science.tool(simple: true) #=> "Microcentrifuge"

Parameters:

  • simple (Boolean) (defaults to: false)

    Whether to generate simple realistic tool names, (no Q-word).

Returns:

  • (String)

Available since:

  • next
