Serialization and Deserialization of Messages

This feature allows for the serialization and deserialization of Cucumber messages. It's useful for transmitting test results over a network or storing them in a file. The code sample demonstrates how to create an Envelope message, serialize it to a binary format, and then deserialize it back to a message object.

"use strict";
const { messages } = require('@cucumber/messages');
const { Envelope } = messages;
const envelope = Envelope.fromObject({ testStepFinished: { testStepResult: { status: 'PASSED' } } });
const serialized = Envelope.encode(envelope).finish();
const deserialized = Envelope.decode(serialized);

Creating and Working with Messages

This feature involves creating and manipulating various types of messages defined by the package, such as test cases, test steps, and results. The code sample shows how to create a TestCase message with specific properties.

"use strict";
const { messages } = require('@cucumber/messages');
const { TestCase } = messages;
const testCase = TestCase.create({ id: '1', pickleId: '2' });
console.log(testCase);
