cypress-controls-ext

Extension to embed controls to controls panel in cypress app

Can have event listeners and custom style

Setup

Prerequisites:

• cypress installed in project

Steps:

1. install package

   npm i --save-dev cypress-controls-ext
   

   or

   yarn add -D cypress-controls-ext
   

2. create control - object of type SetupControlSettings

   // simple example, you can put that into separate file
   export const myControl: SetupControlSettings = {
      // uniq id to html element
      id: 'my-button',
   
      // in what modes to inject control
      mode: {
        run: false,
        open: true,
      },
   
      // html for your control
      control: () => `<button id="myBut">Button</button>`,
   
      // event listener for control
      // add correct selector (with parentId)
      addEventListener: (parentId: string, listener: ListenerSetting) => {
        listener('#' + parentId + ' #myBut', 'click', () => {
          // will log message on #myBut click
          Cypress.log({ name: 'CLICK', message: '#myBut' });
        });
      },
      // also optional style handler could be added here
    };
   

3. register control before tests

   You can do that

   • by setupControlsExtensionWithEvent(myControl); in support/index.js file : constrol will be Cypress.on('test:before:run:async'...
   • by setupControlsExtension(myControl) - this doesn't use event

Features

• You can add several controls
• You can add style handler

    ...
      mode: { run: true, open: true },
      id: 'myButton',
      style: (parentId: string) => `
        #${parentId} {
          background-color: '#569532'};
        }
  
        #${parentId} .turn-mock-on-label {
          padding: 5px;
          color: red;
          font-weight: bold;
        }
      `,
  ...
