Create Test Cases​

In most cases, to create test cases, you can use the pict function. The main feature of this function is that you can use any data type for the values.

import { pict } from "pict-node";
import { createOrder } from "./createOrder.js";

// 1. Define test model
const model = [
  {
    key: "customer",
    values: ["Individuals", "Companies", "Partners"],
  },
  {
    key: "time",
    values: ["05:00", "11:99", "15:00", "21:30", "23:59"],
  },
  {
    key: "payment",
    values: ["VISA", "MasterCard", "PayPal", "Qiwi"],
  },
  {
    key: "product",
    values: [
      {
        id: 1732,
      },
      {
        id: 319,
      },
      {
        id: 872,
      },
      {
        id: 650,
      },
    ],
  },
  {
    key: "discount",
    values: [true, false],
  },
];

// 2. Create test cases
const cases = await pict({ model });

// 3. Iterate test cases
for (const { customer, time, payment, product, discount } of cases) {
  const result = createOrder({
    customer,
    time,
    payment,
    product,
    discount,
  });

  // Verify that the function returns the expected result
  expect(result).toBe("The order has been created");
}

Test cases are an array with generated values.

[
  // ... ... ...
  {
    customer: "Individuals",
    time: "21:30",
    payment: "PayPal",
    product: {
      id: 319,
    },
    discount: false,
  },
  {
    customer: "Individuals",
    time: "11:99",
    payment: "MasterCard",
    product: {
      id: 872,
    },
    discount: true,
  },
  // ... ... ...
  {
    customer: "Partners",
    time: "23:59",
    payment: "Qiwi",
    product: {
      id: 872,
    },
    discount: true,
  },
  // ... ... ...
];

By default, the library generates a pair-wise test suite (all pairs covered), but the order can be set by option order to a value larger than two.

const cases = await pict(
  {
    model,
  },
  {
    order: 3,
  }
);
