Tests Base Framework

This repository has the role of a base framework to use on all tests projects.

Stack

• Playwright as a node library to automate interaction with Chromium, Firefox and WebKit.

Browser Helper

Used as a wrapper for Playwright functions, it aims to simplify launching browsers, context and opening new tabs using environment parameters.

Here are some functions wrapped on this helper :

• getBrowserOptions: Each browser type use different options to start, this function use the env var BROWSER to select the options to use.
• createBrowser: When the browser type is chosen and its options are defined, this function attempt to launch the browser 3 times before throwing an error. Sometimes the browser fail or crash when started, that's why multiple attempts are done.
• closeBrowser: After finishing the run, this function is called to destroy all browser instances or temporary files used on the run.
• createContext: A browser could have different contexts depending on the platform to test on, this function simplify the use.
• closeContext: After finishing a scenario, this function is called to destroy all instances created by the context.
• addTab: To test on a browser instance, we need a tab to perform action on, this function add a new tab and return it on the test.
• closeTab: After finishing work on a tab (and we have more than one tab), this function could used to close it.

Examples

A small example was done to test the browser helper, the scenario of the test is:

• Go to First Visit page using the menu

Before running examples, dependencies must be installed.

npm ci

To run tests :
