Implementing the provider changes

Open up the terminal for your provider project.

Run make test to make sure everything is passing before you start.

Get the URL of the new pact:

Run PACT_URL=<PACT URL HERE> make test again. This test should correctly fail with the error Could not find key "color" in the output.

Make the test pass by adding a color field to product/product.js, and adding the new color argument to the Product initialization lines in product/product.repository.js and the provider states in product/product.pact.test.js.

constructor(id, type, name, version, color) {
  this.id = id;
  this.type = type;
  this.name = name;
  this.version = version;
  this.color = color;
}

constructor() {
    this.products = new Map([
        ["09", new Product("09", "CREDIT_CARD", "Gem Visa", "v1", "green")],
        ["10", new Product("10", "CREDIT_CARD", "28 Degrees", "v1", "blue")],
        ["11", new Product("11", "PERSONAL_LOAN", "MyFlexiPay", "v2", "yellow")],
    ]);
}

const stateHandlers = {
  "products exists": () => {
    controller.repository.products = new Map([
      ["10", new Product("10", "CREDIT_CARD", "28 Degrees", "v1","blue")],
    ]);
  },
  "products exist": () => {
    controller.repository.products = new Map([
      ["10", new Product("10", "CREDIT_CARD", "28 Degrees", "v1","blue")],
    ]);
  },
  "a product with ID 10 exists": () => {
    controller.repository.products = new Map([
      ["10", new Product("10", "CREDIT_CARD", "28 Degrees", "v1","blue")],
    ]);
  },
  "a product with ID 11 does not exist": () => {
    controller.repository.products = new Map();
  },
};

Run PACT_URL=<PACT URL HERE> make test and you should have a passing test suite. ✅
