@shelex/cypress-wait-network

Deprecation notice

Users have reported that in recent Cypress versions (v12+) requests are not being tracked.
I can confirm that is happening due to internal changes in Cypress behavior and some functionality that this plugin relies on was removed.
Thus I see no reason in re-developing it.
In case you consider migrating to Cypress v12+ please replace this plugin with cypress-network-idle which utilizes intercept functionality instead of internals and should work fine and cover your use case.

Documentation

Plugin that adds cy.waitForNetwork command that ensures background network requests are finished You can also enable automatic waiting before every cy.get by setting env var waitForRequestsBeforeCyGet

Installation

• download package:

  • using yarn:

  yarn add -D @shelex/cypress-wait-network

  • using npm:

  npm i -D @shelex/cypress-wait-network
  

• register command in cypress/support/index.js file:

  • with import:

  import '@shelex/cypress-wait-network';

  • or with require:

  require('@shelex/cypress-wait-network');

• for IntelliSense (autocompletion) support in your IDE

  • add to your files:

  /// <reference types="@shelex/cypress-wait-network" />

  • or update your tsconfig.json include section:

  "include": [
      "cypress",
      "@shelex/cypress-wait-network",
  ]

Options

Command cy.waitForNetwork accepts an options object with such properties:

property	description	default
timeout	timeout for requests loading (ms)	Cypress.config().responseTimeout (30s)
idle	time to wait till network is recognized as idle (ms)*	1000 ms

* idle could be used to apply waiting strategy to your specific needs, as requests may be triggered after default idle is finished, usually caused by debouncing on front-end. By default command uses 1 second idle check which means in case there are no requests loading - it will wait minimum ~ 1s before finishing command, in case there are requests - it will reset timer until there would be at least 1 second when all responses are received, no other requests loading so we can treat network as idle.

Configuration

Plugin is customizable via Cypress environment variables:

env variable name	description	default
waitForRequestsBeforeCyGet	run waitForNetwork command before every cy.get	false

This options could be passed:

• via cypress.json

  {
      "env": {
          "waitForRequestsBeforeCyGet": true
      }
  }

• via command line: as Cypress environment variables are used please take into account that cli should have only one argument --env or -e, otherwise values will not be passed

  ```bash
  yarn cypress run --env waitForRequestsBeforeCyGet=true
  
  # for windows:
  yarn cypress run --env  "waitForRequestsBeforeCyGet=true","otherEnvVar=value"
  ```
  

Credits

Inspired by Gleb Bahmutov [e-mail] who made cypress-network-idle plugin that has same purpose. Moreover command cy.waitForNetworkIdle(2000) from cypress-network-idle is quite same as cy.waitForNetwork({ idle: 2000 }) from this package, first is based on interception and counters, this package just checks requests and responses from cy.state
