Instance Method Details

#from_json(json_string) ⇒ Object

Returns a new Message - or messages into an array - deserialized from the given json document. CamelCased keys are properly converted to snake_cased attributes in the process

Cucumber::Messages::Duration.from_json('{"seconds":1,"nanos":42}')               # => #<Cucumber::Messages::Duration:0x00007efda134c290 @seconds=1, @nanos=42>
Cucumber::Messages::PickleTag.from_json('{"name":"foo","astNodeId":"abc-def"}')  # => #<Cucumber::Messages::PickleTag:0x00007efda138cdb8 @name="foo", @ast_node_id="abc-def">

It is recursive so embedded messages are also processed.

json_string = { location: { line: 2 }, text: "comment" }.to_json
Cucumber::Messages::Comment.from_json(json_string)  # => #<Cucumber::Messages::Comment:0x00007efda6abf888 @location=#<Cucumber::Messages::Location:0x00007efda6abf978 @line=2, @column=nil>, @text="comment">

json_string = { uri: 'file:///...', comments: [{text: 'text comment'}, {text: 'another comment'}]}.to_json
Cucumber::Messages::GherkinDocument.from_json(json_string)  # => #<Cucumber::Messages::GherkinDocument:0x00007efda11e6a90 ... @comments=[#<Cucumber::Messages::Comment:0x00007efda11e6e50 ..., #<Cucumber::Messages::Comment:0x00007efda11e6b58 ...>]>
