💡 Sample Test Scripts

✅ Status Code Assertion

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

🔍 Response Body Assertion

pm.test("Response has user id", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.id).to.not.be.null;
    pm.expect(jsonData.name).to.eql("Xavier");
});

⏱️ Response Time Check

pm.test("Response time is less than 500ms", function () {
    pm.expect(pm.response.responseTime).to.be.below(500);
});

🔐 Set Bearer Token Dynamically

var jsonData = pm.response.json();
pm.environment.set("auth_token", jsonData.token);
