Cypress - CircleCI

Running Cypress tests in parallel on CircleCI and Currents dashboard

TL;DR Check out the example repository:

https://github.com/currents-dev/circleci-example

This is an example repository that showcases using CircleCI with Currents.dev.

We are hosting independent versions of the Cypress App and docker images with pre-installed binaries. Please refer to the documentation for the list of supported binaries and versions.

The example config file installs the custom Cypress App and runs 3 containers with Cypress tests in parallel using various setup scenarios.

Prerequisites

• Create an account at https:/app.currents.dev.

• Obtain ProjectId and Record Key.

• Set CURRENTS_RECORD_KEY:

  • create CircleCI context and set CURRENTS_RECORD_KEY.

  • alternatively, set Environment variable CURRENTS_RECORD_KEY

• Follow the setup instructions at https://currents.dev/readme/integration-with-cypress/cypress-cloud to create currents.config.js set your projectId

Bare CircleCI configuration

Please refer to the setup scenario that fits your needs.

Use Docker image with pre-installed Cypress

CircleCI configuration that uses Docker image with pre-installed cypress app. Refer to the documentation for the list of supported binaries and versions.

version: 2.1

jobs:
  # Use pre-built image with alternative Cypress binary
  noorbs currents-image:
    parallelism: 3
    docker:
      - image: currentsdev/cypress-included:12.17.4
    steps:
      - checkout
      - run:
          name: Install Dependencies
          command: npm ci
      - run:
          name: Run tests
          command: npx cypress-cloud run --parallel --record --key $CURRENTS_RECORD_KEY

workflows:
  noorbs:
    jobs:
      - noorbs currents-image:
          context: currents

Explicitly downloading alternative Cypress binary

CircleCI configuration that explicitly downloads alternative Cypress binary. Refer to the documentation for the list of supported binaries and versions.

version: 2.1

jobs:
  # Explicitly download Cypress binary
  noorbs explicit-download:
    parallelism: 3
    docker:
      - image: cypress/base:18.16.1
    steps:
      - checkout
      - run:
          name: Install dependencies
          command: npm ci
      - run:
          name: Download Alternative Cypress Binaries
          command: CYPRESS_DOWNLOAD_MIRROR=https://cy-cdn.currents.dev npx cypress install --force
      - run:
          name: Run tests
          command: npx cypress-cloud run --parallel --record --key $CURRENTS_RECORD_KEY

    jobs:
      - noorbs explicit-download:
          context: currents

Using Cypress Orb with default executor

Cypress Orb has pre-defined commands that facilitate creating CircleCI configuration. The examples below show how to integrate Cypress tests with Currents using Cypress Orb and various setup scenarios.

The examples below use Custom Test Command to run cypress-cloud for recording test results and parallelization with Currents.dev

Using cypress/default executor example

The configuration below uses the default cypress/default CircleCI executor and installs custom Cypress binary during cypress/install step:

version: 2.1

orbs:
  cypress: cypress-io/cypress@3

jobs:
  # Use cypress/default executor example
  default-executor cypress-install:
    executor: cypress/default
    steps:
      - cypress/install:
          post-install: CYPRESS_DOWNLOAD_MIRROR=https://cy-cdn.currents.dev npx cypress install --force
      - persist_to_workspace:
          root: ~/
          paths:
            - .cache/Cypress
            - project

  default-executor cypress-run:
    executor: cypress/default
    parallelism: 3
    steps:
      - attach_workspace:
          at: ~/
      - cypress/run-tests:
          cypress-command: npx cypress-cloud run --parallel --record --key $CURRENTS_RECORD_KEY

workflows:
  with-orbs default-executor:
    jobs:
      - default-executor cypress-install
      - default-executor cypress-run:
          context: currents
          requires:
            - default-executor cypress-install

Using custom executor with pre-installed Cypress App

The configuration below uses the custom executor with pre-installed Cypress App.

version: 2.1

orbs:
  cypress: cypress-io/cypress@3

executors:
  # define custom executors
  currents-executor:
    docker:
      - image: currentsdev/cypress-included:12.17.4

jobs:
  # Use currentsdev executor with pre-installed Cypress binary
  custom-executor cypress-install:
    executor: currents-executor
    steps:
      - cypress/install
      - persist_to_workspace:
          root: ~/
          paths:
            - project

  custom-executor cypress-run:
    executor: currents-executor
    parallelism: 3
    steps:
      - attach_workspace:
          at: ~/
      - cypress/run-tests:
          cypress-command: npx cypress-cloud run --parallel --record --key $CURRENTS_RECORD_KEY

workflows:
  with-orbs custom-executor:
    jobs:
      - custom-executor cypress-run:
          context: currents

Use Docker image with pre-installed Cypress

CircleCI configuration that uses Docker image with pre-installed cypress app. Refer to the documentation for the list of supported binaries and versions.
