Introduction

Plugin that allows interaction with MongoDB server using Cypress commands.

Installation

run npm install cypress-mongodb configure (see below) profit

Supported and tested system versions

| | Versions | | ---------------------- | ------------------------ | | MongoDB | 4.4, 5.0, 6.0 | | Node | 16.20, 18.16, 20.5 | | MongoDB Node.js Driver | 4.10.0 |

known issues

If you use mongodb dependency in your project, it hast to be version <=4.10.0, otherwise you'll get a Webpack compilation error

Plugin configuration

In your cypress.config.js file, make the following changes:

1. Add the necessary mongodb environment variables under env block
2. Import and load the plugin under e2e block

import { configurePlugin } from 'cypress-mongodb';

module.exports = defineConfig({
    env: {
        mongodb: {
            uri: 'mongodb://localhost:27017',
            database: 'database_name',
            collection: 'collection_name'
        }
    },
    e2e: {
        setupNodeEvents(on, config) {
            configurePlugin(on);
        }
    }
});

Note: only mongodb.uri is mandatory, you can always override/set database and collection names in each cypress mongodb command using options. You can set both local and remote urls.

Finally, in your cypress/support/e2e.js add the following:

import { addCommands } from 'cypress-mongodb/dist/index-browser';
addCommands();
