IDE Integration

File Opener Preference

When clicking on a file path or an error in the command log, Cypress will attempt to open the file on your system. If the editor supports inline highlighting of the file, the file will open with the cursor located on the line and column of interest.

The first time you click a file path, Cypress will prompt you to select which location you prefer to open the file. You can choose to open it in your:

• File system (e.g. Finder on MacOS, File Explore on Windows)
• An IDE located on your system
• A specified application path

After setting your file opener preference, any files will automatically open in your selected application without prompting you to choose. If you want to change your selection, you can do so in the Settings tab of Cypress by clicking under File Opener Preference.

Extensions & Plugins

There are many third-party IDE extensions and plugins to help integrate your IDE with Cypress.

Visual Studio Code

• Cypress Fixture-IntelliSense: Supports your cy.fixture() and cy.route(..., "fixture:") commands by providing intellisense for existing fixtures.
• Cypress Helper: Various helpers and commands for integration with Cypress.
• Cypress Snippets: Useful Cypress code snippets.
• Cypress Snippets: This extension includes the newest and most common cypress snippets.
• Open Cypress: Allows you to open Cypress specs and single it() blocks directly from VS Code.
• Test Utils: Easily add or remove .only and .skip modifiers with keyboard shortcuts or the command palette.

IntelliJ Platform

Compatible with IntelliJ IDEA, AppCode, CLion, GoLand, PhpStorm, PyCharm, Rider, RubyMine, and WebStorm.

• Cypress Support: Integrates Cypress under the common Intellij test framework.
• Cypress Support Pro: An improved version of Cypress Support plugin with debugging from the IDE, advanced autocomplete, built-in recorder and other features.

Intelligent Code Completion

Writing Tests

Features

IntelliSense is available for Cypress. It offers intelligent code suggestions directly in your IDE while writing tests. A typical IntelliSense popup shows command definition, a code example and a link to the full documentation page.

Autocomplete while typing Cypress commands

Signature help when writing and hovering on Cypress commands

Autocomplete while typing assertion chains, including only showing DOM assertions if testing on a DOM element.

Set up in your Dev Environment

This document assumes you have installed Cypress.

Cypress comes with TypeScript type declarations included. Modern text editors can use these type declarations to show IntelliSense inside spec files.

Triple slash directives

The simplest way to see IntelliSense when typing a Cypress command or assertion is to add a triple-slash directive to the head of your JavaScript or TypeScript testing file. This will turn the IntelliSense on a per file basis. Copy the comment line below and paste it into your spec file.

/// <reference types="Cypress" />

If you write custom commands and provide TypeScript definitions for them, you can use the triple slash directives to show IntelliSense, even if your project uses only JavaScript. For example, if your custom commands are written in cypress/support/commands.js and you describe them in cypress/support/index.d.ts use:

// type definitions for Cypress object "cy"
/// <reference types="cypress" />

// type definitions for custom commands like "createDefaultTodos"
/// <reference types="../support" />

See the cypress-example-todomvc repository for a working example.

If the triple slash directive does not work, please refer to your code editor in TypeScript's Editor Support doc and follow the instructions for your IDE to get TypeScript support and intelligent code completion configured in your developer environment first. TypeScript support is built in for Visual Studio Code, Visual Studio, and WebStorm - all other editors require extra setup.

Reference type declarations via jsconfig

Instead of adding triple slash directives to each JavaScript spec file, some IDEs (like VS Code) understand a common jsconfig.json file in the root of the project. In that file, you can include the Cypress module and your test folders.

{
  "include": ["./node_modules/cypress", "cypress/**/*.js"]
}

The Intelligent Code Completion should now show help for cy commands inside regular JavaScript spec files.

Reference type declarations via tsconfig

Adding a tsconfig.json inside your cypress folder with the following configuration should get intelligent code completion working.

{
  "compilerOptions": {
    "allowJs": true,
    "types": ["cypress"]
  },
  "include": ["**/*.*"]
}
