atom(options \\ []) View Source 
atom(keyword()) :: StreamData.t()

Generates atoms.

Options

  • :length - (integer or range) if an integer, the exact length the generated atoms should be; if a range, the range in which the length of the generated atoms should be. If provided, :min_length and :max_length are ignored.

  • :min_length - (integer) the minimum length of the generated atoms.

  • :max_length - (integer) the maximum length of the generated atoms.

Examples 

Enum.take(ExopData.CommonGenerators.atom(), 3)
#=> [:xF, :y, :B_]

map(data_map, optional_keys) View Source 
map([StreamData.t()], [atom()]) :: StreamData.t()

Allow to generate maps with optional keys and generated values.

data_map is a map of fixed_key => data pairs. optional_keys is a list of optional keys, which can be or cannot be in final result.

Examples 

data = ExopData.CommonGenerators.map(
  %{
    integer: StreamData.integer(),
    binary: StreamData.binary(),
  },
  [:integer]
)
Enum.take(data, 3)
#=> [%{binary: "a", integer: 1}, %{binary: "b"}, %{binary: "c", integer: 2}]
