This is a powerful feature of Playwright which intercepts Network requests. Remember that our pages/index.js file makes a request to /api/book during getServerSideProps. Internally it does this by looking in your root level config directory for a json file name that matched the process.ENV. Next I define my teardown process, that runs only after all test suites have completed. As a side note, I am building a service called happykit.dev which allows you to use Feature Flags in your Next.js applications.

Note that this setup is brand new and pretty experimental. The port gets then passed over to Playwright as a baseURL when creating the context browser.newContext([options]). This is just out of convenience so that we dont have to repeat import { rest } from "msw" in every test file. I prefer women who cook good food, who speak three languages, and who go mountain hiking - what if it is a woman who only has one of the attributes? authenticate with the storage service using Azure Active Directory. How to constrain regression coefficients to be proportional. See TestConfig properties for available configuration options.. The next step is to tell Mocha where to find the file. Use the --file argument when calling Mocha via NPM scripts or use a mocha.opts file. In this tutorial, we are going to write two simple test cases. This should be straightforward to integrate. One is Named Exports and other is Default Exports. This is only meant as a small time safer. My repository took some time to setup, and includes some scripts for its own maintenance. Create scenarios with different contexts for different users and run them .

Should we burninate the [variations] tag? To launch a server during the tests, use the webServer option in the configuration file..
