Faker is a pure Elixir library for generating fake data.
- add
{:faker, "~> 0.9"}
to your deps inmix.exs
; - add
:faker
to list of your applications; - jump to usage examples.
Example mix.exs
:
...
def application do
[applications: [:logger, :faker]]
end
...
defp deps do
[{:faker, "~> 0.9"}]
end
...
In your mix.exs
file, add the :faker
project to your dependencies
(optionally include the version):
defp deps do
[{:faker, "~> 0.9", only: :test}]
end
Do a mix deps.get
to fetch the dependency. That's it.
If you want to use faker
outside tests remove , only: :test
part.
- OTP18+
- Elixir 1.3+
You need to start :faker
application, but due to the many usages of fake data,
(seed database, tests, etc) there's no right place to do it. For example, if you
want to use it in tests, just add Faker.start
to test/test_helper.exs
, then,
use any function described in the documentation or
in usage examples.
- If you get a message like the one below when you call
Faker.Address.city
, you need to add:faker
to your application's mix file, in theapplications
function, as above.
** (FunctionClauseError) no function clause matching in Faker.Address.city_count/1
lib/faker/address.ex:48: Faker.Address.city_count(nil)
lib/faker/address.ex:41: Faker.Address.city/0
Faker was designed as a lightweight library, that's why it can be easily used with other tools.
You can build templates for testing purposes with the Blacksmith project. See the Blacksmith readme for details.
