Examples
Voorhees.matches_payload?
Expected payload keys can be either strings or atoms
iex> payload = ~S[{ "foo": 1, "bar": "baz" }]
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => "baz" })
true
Extra key/value pairs in payload are ignored
iex> payload = ~S[{ "foo": 1, "bar": "baz", "boo": 3 }]
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => "baz" })
true
Extra key/value pairs in expected payload cause the validation to fail
iex> payload = ~S[{ "foo": 1, "bar": "baz"}]
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => "baz", :boo => 3 })
false
Validates scalar lists
iex> payload = ~S/{ "foo": 1, "bar": ["baz"]}/
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => ["baz"] })
true
# Order is respected
iex> payload = ~S/{ "foo": 1, "bar": [1, "baz"]}/
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => ["baz", 1] })
false
Validates lists of objects
iex> payload = ~S/[{ "foo": 1, "bar": { "baz": 2 }}]/
iex> Voorhees.matches_payload?(payload, [%{ :foo => 1, "bar" => %{ "baz" => 2 } }])
true
Validates nested objects
iex> payload = ~S/{ "foo": 1, "bar": { "baz": 2 }}/
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => %{ "baz" => 2 } })
true
Validates nested lists of objects
iex> payload = ~S/{ "foo": 1, "bar": [{ "baz": 2 }]}/
iex> Voorhees.matches_payload?(payload, %{ :foo => 1, "bar" => [%{ "baz" => 2 }] })
true
Voorhees.matches_schema?
Validating simple objects
iex> payload = ~S[{ "foo": 1, "bar": "baz" }]
iex> Voorhees.matches_schema?(payload, [:foo, "bar"]) # Property names can be strings or atoms
true
# Extra keys
iex> payload = ~S[{ "foo": 1, "bar": "baz", "boo": 3 }]
iex> Voorhees.matches_schema?(payload, [:foo, "bar"])
false
# Missing keys
iex> payload = ~S[{ "foo": 1 }]
iex> Voorhees.matches_schema?(payload, [:foo, "bar"])
false
Validating lists of objects
iex> payload = ~S/[{ "foo": 1, "bar": "baz" },{ "foo": 2, "bar": "baz" }]/
iex> Voorhees.matches_schema?(payload, [:foo, "bar"])
true
Validating nested lists of objects
iex> payload = ~S/{ "foo": 1, "bar": [{ "baz": 2 }]}/
iex> Voorhees.matches_schema?(payload, [:foo, bar: [:baz]])
true
Validating that a property is a list of scalar values
iex> payload = ~S/{ "foo": 1, "bar": ["baz", 2]}/
iex> Voorhees.matches_schema?(payload, [:foo, bar: []])
true
