CYPRESS + POSTGRES Integration step by step

CYPRESS + POSTGRES Integration step by step

Here are the general steps to integrate Cypress with Postgres:

  1. Install the necessary dependencies:
  • Cypress (npm install cypress)
  • A library for interacting with Postgres, such as cypress-pg (npm install cypress-pg) or pg-promise (npm install pg-promise)
  1. Set up a test environment with a running Postgres server. This can be done by either installing Postgres on your local machine or by creating a remote server.
  2. Create a new file in your Cypress project where you will store your database configuration. This should include details like the host, port, username, and password of your Postgres server.
  3. In your Cypress tests, import the library you chose in step 1, and use the methods provided by the library to connect to the Postgres server using the configuration file.
  4. Write Cypress test to interact with your Postgres server, this can include running SQL queries and checking the results.
  5. Run your Cypress tests to check that the integration is working correctly.

Here is an example of Cypress test that uses the cypress-pg library to check if the number of rows in the table is equal to the expected number.

describe('Postgres Test', function() {
  it('Check the number of rows in a table', function() {
    cy.pg('SELECT COUNT(*) FROM my_table')
      .then(res => {
        expect(res[0].count).to.equal(10)
      })
  })
})

It is important to note that Cypress is a front-end testing tool and Postgres is a back-end database, so the integration will likely involve setting up a test environment with a Postgres server running, and configuring your Cypress tests to connect to that server.
