Functions

Put request header "content-type: application/json" on the conn.

Remove volatile fields from maps in the data. Volatile fields like "id" mess up test comparisons. Recursively cleans maps and lists.

Generate a JSON Web Key for testing purposes. See gen_jwt/2 for details.

Generate a JSON Web Signature for testing purposes. See gen_jwt/2 for details.

Generate a JSON Web Token for testing purposes. It is possible to override parts of the signing key, payload and signature to test with different scopes, expiration times, issuers, key ID's etc, override the entire signing key, payload or signature. The defaults should generate a valid JWT. For use with endpoints secured with PhoenixApiToolkit.Security.Oauth2Plug.

Generate a JSON Web Token payload for testing purposes. See gen_jwt/2 for details.

Adds a HMAC-SHA256 signature to the connection's authorization header for the request body. Use create_hmac_plug_body/4 to generate a valid body. For use with endpoints secured with PhoenixApiToolkit.Security.HmacPlug.

Add JWT to the conn. A valid, signed JWT can be generated by gen_jwt/2.

Put a whole map (or keyword list) of query params on a %Conn{}.

Put a raw request body in conn.assigns.raw_body for testing purposes.

Returns an example jwks for use by gen_jwt/2, as base64-encoded JSON.

Converts a map with atoms in it as keys or values to a map with just strings. Works on nested maps as well.

application_json(conn)

View Source
application_json(Plug.Conn.t()) :: Plug.Conn.t()

Put request header "content-type: application/json" on the conn.

Examples

use Plug.Test

iex> conn(:post, "/") |> application_json() |> get_req_header("content-type")
["application/json"]

clean_volatile_fields(data)

View Source
clean_volatile_fields(any()) :: any()

Remove volatile fields from maps in the data. Volatile fields like "id" mess up test comparisons. Recursively cleans maps and lists.

Examples

iex> my_data = [
...>   %{
...>     "updated_at" => 12345
...>   },
...>   %{
...>     "some_thing" => [
...>       %{
...>         "id" => 1
...>       },
...>       12345
...>     ]
...>   }
...> ]
iex> clean_volatile_fields(my_data)
[%{}, %{"some_thing" => [%{}, 12345]}]

create_hmac_plug_body(path, method, contents \\ %{}, timestamp \\ DateTime.utc_now() |> DateTime.to_unix(:second))

View Source
create_hmac_plug_body(binary(), binary(), any(), integer()) :: binary()

Generate a request body for an endpoint secured with PhoenixApiToolkit.Security.HmacPlug. Use put_hmac/3 to generate a valid signature.

It is possible to override the timestamp set in the request body. The default generates a valid request body, so overrides are not necessary unless you wish to test the HMAC verification itself.

Examples

iex> create_hmac_plug_body("/hello", "GET", %{hello: "world"}, 12345) |> Jason.decode!()
%{
  "contents" => %{"hello" => "world"},
  "method" => "GET",
  "path" => "/hello",
  "timestamp" => 12345
}

gen_jwk(overrides \\ [])

View Source
gen_jwk(map() | keyword()) :: map()

Generate a JSON Web Key for testing purposes. See gen_jwt/2 for details.

The default is the first key of test_jwks/0.

Examples

iex> gen_jwk()["kid"]
"my_test_key"

iex> gen_jwk(kid: "other key")["kid"]
"other key"
Link to this function

gen_jws(overrides \\ [])

View Source
gen_jws(map() | keyword()) :: map()

Generate a JSON Web Signature for testing purposes. See gen_jwt/2 for details.

The defaults are the "alg" and "kid" values of the first key of test_jwks/0.

Examples

iex> gen_jws()
%{"alg" => "RS256", "kid" => "my_test_key"}

iex> gen_jws(alg: "RS512")["alg"]
"RS512"
Link to this function

gen_jwt(defaults, overrides \\ [])

View Source
gen_jwt(gen_jwt_defaults(), gen_jwt_opts()) :: binary()

Generate a JSON Web Token for testing purposes. It is possible to override parts of the signing key, payload and signature to test with different scopes, expiration times, issuers, key ID's etc, override the entire signing key, payload or signature. The defaults should generate a valid JWT. For use with endpoints secured with PhoenixApiToolkit.Security.Oauth2Plug.

Examples

@jwt_defaults %{
  jwk: gen_jwk(),
  jws: gen_jws(),
  payload: gen_payload(iss: "http://my-oauth2-provider")
}

# the defaults as created above generate a valid JWT, provided that the claims match those verified
# the header, payload and signature can be inspected using JOSE.JWS.peek* functions
iex> jwt = gen_jwt(@jwt_defaults)
iex> jwt |> JOSE.JWS.peek_protected() |> Jason.decode!()
%{"alg" => "RS256", "kid" => "my_test_key", "typ" => "JWT"}
iex> jwt |> JOSE.JWS.peek_payload() |> Jason.decode!() |> Map.drop(["exp"])
%{"iss" => "http://my-oauth2-provider"}

# the jwk, payload and jws can be overriden for testing purposes
iex> gen_jwt(@jwt_defaults, payload: %{}) |> JOSE.JWS.peek_payload() |> Jason.decode!()
%{}

# this is most useful when combined with gen_jwk/gen_payload/gen_jws functions
# to override parts of the jwk/payload/jws
iex> gen_jwt(@jwt_defaults, jws: gen_jws(kid: "other key")) |> JOSE.JWS.peek_protected() |> Jason.decode!()
%{"alg" => "RS256", "kid" => "other key", "typ" => "JWT"}
iex> gen_jwt(@jwt_defaults, payload: gen_payload(exp: 12345)) |> JOSE.JWS.peek_payload() |> Jason.decode!() |> Map.get("exp")
12345
Link to this function

gen_payload(overrides \\ [])

View Source
gen_payload(map() | keyword()) :: map()

Generate a JSON Web Token payload for testing purposes. See gen_jwt/2 for details.

The default only has an "exp" claim set to 5 minutes in the future.

Examples

iex> gen_payload()["exp"] > 0
true

iex> gen_payload(iss: "something")["iss"]
"something"

put_hmac(conn, body, secret)

View Source
put_hmac(Plug.Conn.t(), binary(), binary()) :: Plug.Conn.t()

Adds a HMAC-SHA256 signature to the connection's authorization header for the request body. Use create_hmac_plug_body/4 to generate a valid body. For use with endpoints secured with PhoenixApiToolkit.Security.HmacPlug.

It is possible to override the HMAC secret. The default generates a valid signature, so overrides are not necessary unless you wish to test the HMAC verification itself.

Examples

use Plug.Test

iex> body = %{greeting: "world"} |> Jason.encode!()
iex> conn = conn(:post, "/hello", body)
iex> put_hmac(conn, body, "supersecretkey") |> get_req_header("authorization")
["oseq9TrQc/cyOBU7ujrkKM07tFewcVoaLRK0MgslSos="]

Add JWT to the conn. A valid, signed JWT can be generated by gen_jwt/2.

Examples

use Plug.Test

iex> conn(:get, "/") |> put_jwt("my_jwt") |> get_req_header("authorization")
["Bearer: my_jwt"]
Link to this function

put_query_params(conn, params)

View Source
put_query_params(Plug.Conn.t(), map() | keyword()) :: Plug.Conn.t()

Put a whole map (or keyword list) of query params on a %Conn{}.

Examples

use Plug.Test

iex> conn(:get, "/") |> put_query_params(user: "Peter") |> Map.get(:query_params)

Examples

use Plug.Test

iex> body = %{hello: "world"}
iex> raw_body = body |> Jason.encode!()
iex> conn = conn(:post, "/") |> put_raw_body(raw_body)

test_jwks()

View Source
test_jwks() :: binary()

to_string_map(map)

View Source
to_string_map(map()) :: map()
