Cypress Feature “Test Replay” Launched: Let’s Play With Test Replay
Problem Statement
Before Cypress v13
, test failures in CI have historically been captured through screenshots, videos, and stack trace outputs, but these artifacts provide limited information.
So Cypress comes with a new feature Test Replay in version 13.0.0. The introduction of features like “Test Replay” in Cypress v13 aims to bridge this gap by providing developers with a way to replay the exact test run and inspect various Aspects of it, such as DOM interactions, network requests, console logs, JavaScript errors, and more

SQL Query Optimization: Combining Multiple Joins for Improved Performance
I'm working on an SQL query for a complex reporting system that involves multiple tables and joins. However, the query's performance is not meeting my expectations, and I suspect that the way I've structured my joins might be inefficient.
Here's a simplified version of my query:
SELECT
orders.order_id,
customers.customer_name,
products.product_name,
order_details.quantity,
order_details.unit_price
FROM
orders
JOIN
customers ON orders.customer_id = customers.customer_id
JOIN
order_details ON orders.order_id = order_details.order_id
JOIN
products ON order_details.product_id = products.product_id
WHERE
orders.order_date BETWEEN '2023-01-01' AND '2023-12-31';
While this query returns the correct results, it's taking a significant amount of time to execute, especially when dealing with a large dataset.
I'd like to optimize this query for better performance. Could someone review my SQL code and suggest improvements or alternative approaches to achieve the same result more efficiently? Additionally, are there any indexing strategies or database design considerations that might help enhance the query's speed? Any insights or code optimizations would be greatly appreciated. Thank you!
