38 API - Delete request
🗑️ Playwright Essentials #38 DELETE Requests with Playwright API Testing
In this episode, we explore how to send DELETE requests using Playwright’s API testing capabilities—ideal for removing resources, cleaning up test data, and validating backend behavior. DELETE is a powerful method that permanently removes data, so precision and validation are key.
🎯 What You’ll Learn:
🔧 What Is a DELETE Request?
→ An HTTP method used to remove a resource from the server
→ Typically returns status codes like 200 OK, 202 Accepted, or 204 No Content
→ Often used in REST APIs for deleting users, records, or configurations
📤 Sending a DELETE Request with Playwright
→ Use request.newContext() to send the request:
const apiContext = await request.newContext();
const response = await apiContext.delete('https://api.example.com/users/123', {
headers: {
'Authorization': `Bearer ${token}`,
'Content-Type': 'application/json'
}
});
- 🧠 Validating the Response
→ Check status code:
expect(response.status()).toBe(204); // No Content
→ Optionally assert headers or confirm deletion via a follow-up GET request
📦 Inspecting Headers, Size & Timing
→ Access headers: response.headers()
→ Measure size:
const raw = await response.body();
console.log(`Size: ${raw.byteLength} bytes`);
→ Track response time:
const start = Date.now();
const response = await apiContext.delete(...);
const duration = Date.now() - start;
console.log(`Response time: ${duration}ms`);
🛡️ Best Practices
→ Confirm deletion with a follow-up GET or status check
→ Handle edge cases like 404 Not Found or 403 Forbidden
→ Avoid accidental deletions—use test environments and mock data
→ Log response metadata for audit and performance tracking
🧪 Real-World Use Cases:
Removing test users or sessions
Cleaning up stale data after automation runs
Validating delete permissions and access control
Ensuring backend consistency after resource removal
