Accessing the SQL database using Cypress

Question

Accessing the SQL database using Cypress

I am attempting to establish a connection with an SQL database using Cypress following the guidelines provided in the NPM guide. I have ensured that all dependencies are installed as specified, however, when I run the following query:

 cy.sqlServer('SELECT Email FROM [MyDB].[dbo].[User] WHERE Name ="test"')

I encounter the following error message:

CypressError: The execution of cy.task('sqlServer:execute') failed with the following error:

TypeError: No connection configuration was provided.

It is worth mentioning that my cypress.json file includes the necessary database connection string details. Here is a snippet from the cypress.json file:

{
  "baseUrl": "myurl",
  "db": {
    "userName": "test",
    "password": "test",
    "server": "test\\test",
    "options": {
      "database": "test",
      "encrypt": true,
      "rowCollectionOnRequestCompletion": true
    }
  }    
}

In addition to this, here is a snippet from my plugins/index.js file:

const sqlServer = require('cypress-sql-server');
module.exports = (on, config) => {
  tasks = sqlServer.loadDBPlugin(config.db);
  on('task', tasks);
}

For those seeking a solution like I did:

It seems that Cypress (I am using version 3.8.2 and I'm unsure about the version used by the author of cypress-sql-server) is unable to recognize the custom property 'db' for some reason.

One approach (there are several ways to do this) is to require the cypress configuration in the plugins file and access your custom property from there.

To achieve this, simply modify the plugins/index.js file as follows:

const sqlServer = require('cypress-sql-server');
const dbConfig = require('../../cypress.json');

module.exports = (on, config) => {
  tasks = sqlServer.loadDBPlugin(dbConfig.db);
  on('task', tasks);
}

It appears that the issue lies within the "server": "test\\test" line in your Cypress.json file. It should likely be changed to something like "server": "localhost" or

"server": "localhost\\SQLExpress"

, matching the value you would use in the "Connect to Server" dialog in Microsoft SQL Server Management Studio.

To solve the issue, I successfully resolved it by relocating the configuration settings into the env section within cypress.json:

{
  "env": {
    "db": {
      "host": "localhost",
      "user": "sa",
      "password": "xxxx",
      "database": "CollateralSystem",
      "port": 1433
    }
  }
}

Subsequently, in plugins\index.js:

module.exports = (on, config) => {
  tasks = sqlServer.loadDBPlugin(config.env.db);
  on('task', tasks);
};

Do not forget to add the necessary return statement as shown here:

 const setupDatabase = (on, config) => {
      tasks = sqlServer.loadDBPlugin(config.db);
      on('task', tasks);  
      return tasks
    }
