Challenge 1: Write a Test Script — Possible Solution
====================================================================

pm.test("Status code is 200", () => {
  pm.response.to.have.status(200);
});

pm.test("Product id is 42", () => {
  const data = pm.response.json();
  pm.expect(data.id).to.eql(42);
});

WHY THIS WORKS AS AN ANSWER
------------------------------
Two separate pm.test() blocks, each checking one distinct thing —
this mirrors the chapter's own two-test example (status, then a body
field), keeping each assertion isolated so a failure report clearly
says WHICH specific check failed rather than one big test silently
covering multiple unrelated things.

The first test uses pm.response.to.have.status(200), the same
built-in status assertion from the chapter's reference table — no need
to manually parse anything for a status code check.

The second test calls pm.response.json() to parse the body, then
asserts data.id equals 42 using pm.expect(...).to.eql(...) — eql
performs a value comparison, appropriate here since id is expected to
be the specific number 42, not just "a number" in general (which would
instead use .to.be.a("number"), a weaker check that wouldn't catch the
API returning the wrong product).
