PUT Update User

What you will learn

  • Understand PUT (full replace) vs PATCH (partial) — using PUT as PATCH loses fields
  • Use conditional requests (If-Match) to prevent lost-update races in concurrent edits
  • Assert the response reflects the update — don't trust the status code alone

Description

Update an existing user with full replacement. Verify all fields are updated.

Test Scenario

const response = await request.put('/api/v1/users/1', {
  data: { name: 'Updated', email: 'updated@test.com' }
});
expect(response.status()).toBe(200);
Endpoint/api/v1/users/:id

Testing Tips

  • •PUT replaces entire resource
  • •Send all required fields
  • •Check 200 OK on success
// Playwright - PUT update user
import { test, expect } from '@playwright/test';


test('PUT /api/v1/users/:id', async ({ request }) => {
  const userId = '1';
  const updatedData = {
    name: 'Updated Name',
    email: 'updated@example.com'
  };


  const response = await request.put(`/api/v1/users/${userId}`, {
    data: updatedData
  });


  expect(response.ok()).toBeTruthy();


  const updated = await response.json();
  expect(updated.name).toBe(updatedData.name);
  expect(updated.email).toBe(updatedData.email);
});
