Tests & scripts

Automate checks with pre-request scripts and

qa.test

assertions.

Pre-request Script

Runs before the request is sent. Use it to set headers, compute values, or seed collection variables.

Open the Pre-request Script tab on any request.

Tests

Runs after the response returns. Signoff uses a

qa.*

dialect (familiar if you know Postman

pm.*

).

Example from the Starter Guide Bearer request:

qa.test("Status is 200 OK", function () {
  qa.response.to.have.status(200);
});

var body = qa.response.json();

qa.test("Server accepted the bearer token", function () {
  qa.expect(body.authenticated).to.be.true;
});

Assert & Extract helpers

After Send, use response actions:

Tips

• Keep assertions focused: status, one or two body fields, latency budget.
• Use the bottom Console to debug script output when a test fails.
• Run many tests together with the Collection Runner.
