+# Lab4
+
+## Introduction
+
+In this lab, you will write tests in `main_test.js`. You can learn how to use [Puppeteer](https://pptr.dev/) to tests a web UI.
+
+## Preparation (Important!!!)
+
+1. Sync fork your branch (e.g., `SQLab:312XXXXXX`)
+2. `git checkout -b lab4` (**NOT** your student ID !!!)
+
+## Requirement
+
+1. (100%) Goto https://pptr.dev/, type `chipi chipi chapa chapa` into the search box, click on **1st** result in the **Docs** section, and print the title.
+
+For the detailed steps and hints, please check the slide of this lab.
+
+You can run `validate.sh` in your local to test if you satisfy the requirements.
+
+Please note that you must not alter files other than `main_test.js`. You will get 0 points if
+
+1. you modify other files to achieve requirements.
+2. you can't pass all CI on your PR.
+
+## Submission
+
+You need to open a pull request to your branch (e.g. 312XXXXXX, your student number) and contain the code that satisfies the abovementioned requirements.
+
+Moreover, please submit the URL of your PR to E3. Your submission will only be accepted when you present at both places.
