# Summarizing nightly executions

> Catch up on last night's regression run with the Summarize nightly execution routine in Delegate, without opening Test Manager.

The setup: you are a QA engineer whose team runs a test set called "Regression Suite – API" every night in project MYAPP. You arrive Tuesday morning and want to know how Monday night's run went, without opening Test Manager.

## Prerequisites

Complete the one-time setup in [Setting up and running your first test case](installing-delegate-for-the-testing-profile.md).

## How to

1. Select **Summarize nightly execution** in the **Delegate** Routines panel.
2. Enter the prompt: *"Summarize last night's execution of Regression Suite – API in project MYAPP."*

**Result**

**Delegate** works in the background: it finds the test set, finds the execution that finished overnight in your time zone, pulls pass/fail stats, fetches failing test case logs and their assertions, compares with the previous run to find new failures, and looks back 4–5 runs to spot flaky tests.

You get a summary with the pass rate, top failures, new failures, and flaky test cases, and **Delegate** asks what is next — for example, whether to email the summary or dig into any of the failing test cases. Total time with the routine: about 30 seconds instead of 10–15 minutes.

:::note
This use case is the worked example behind the "Summarize nightly execution" routine described on the [Routines for testing](routines-for-testing.md) page.
