CircleCI

This project is building in CircleCI and can be viewed at the following link

CircleCI Build

See the .circleci folder

  • config.yml - Contains the CircleCI build configuration

The following env vars are read for CircleCI users.

  • CIRCLE_SHA1 - The SHA1 hash of the last commit of the current build
  • CIRCLE_BRANCH - The name of the Git branch currently being built.
  • CIRCLE_USERNAME - The GitHub or Bitbucket username of the user who triggered the build.
  • CIRCLE_BUILD_URL - The URL for the current build.
  • CIRCLE_BUILD_NUM - The number of the CircleCI build.
  • CIRCLE_PULL_REQUEST - Comma-separated list of URLs of the current build’s associated pull requests.
  • CIRCLE_PROJECT_REPONAME - The name of the repository of the current project.
  • CIRCLE_PROJECT_USERNAME - The GitHub or Bitbucket username of the current project.
  • CI_URL="https://circleci.com/api/v1.1/project"
  • CIRCLE_PROJECT_ID - This project ID used in artefact URLS

If you wish to use another CI provider, you can pass any name other than circleci into the CLI flag --ci-provider, which will allow you to enter your own environment variables for CI.

  • CI_URL
  • CI_SHA1,
  • CI_BRANCH,
  • CI_USERNAME,
  • CI_BUILD_URL,
  • CI_BUILD_NUM,
  • CI_PULL_REQUEST,
  • CI_PROJECT_REPONAME
  • CI_PROJECT_USERNAME

CircleCI Artifact Notes

CircleCI have recently changed the API for retrieving API's. A URL is generated for artefacts in the format

https://${CI_BUILD_NUM}-${CI_PROJECT_ID}-gh.circle-artifacts.com/0

You can get the CIRCLE_PROJECT_ID by checking https://circleci.com/docs/api/#artifacts-of-a-build

For example. the ID for this project is 177880476, you can see it in the following URL

https://circleci.com/api/v1.1/project/github/YOU54F/cypress-slack-reporter/1/artifacts

which will return

[ {
  "path" : "root/app/mochareports/.gitignore",
  "pretty_path" : "root/app/mochareports/.gitignore",
  "node_index" : 0,
  "url" : "https://1-177880476-gh.circle-artifacts.com/0/root/app/mochareports/.gitignore"
},
...
]

In order to correctly construct your artifact URL, you will need to manually retrieve this ID and set it as an env var titled CIRCLE_PROJECT_ID

EXPORT CIRCLE_PROJECT_ID=177880476

in windows

SET CIRCLE_PROJECT_ID=177880476

or in your CircleCI project's environment page.

There is also another workaround by setting a destination option in store_artifacts job in config.yml (CircleCI).

- store_artifacts:
          path: ~/path/to/cypress/videos
          destination: cypress/videos

will allow you to access artifacts through https://${CI_BUILD_NUM}-${CI_PROJECT_ID}-gh.circle-artifacts.com/0/cypress/videos/some_test_result.mp4

This is what it says on CircleCI Documentation:

Currently, store_artifacts has two keys: path and destination.

path is a path to the file or directory to be uploaded as artifacts.
destination (Optional) is a prefix added to the artifact paths in the artifacts API. The directory of the file specified in path is used as the default.

Scripted Runner

An example script is here as cli/spec/ts

A example of how you can use this script in your project to:-

  • Run Cypress with Mochawesome & junit reporters
  • Merge mochawesome reports with mochawesome-merge
  • Construct a slack alert with the merged report, screenshots and videos

Either with the cli

./node_modules/.bin/cypress-slack-reporter-full

Or with your own script

rm -rf ./cypress/reports/mocha && npx ts-node script.ts

It can be called with the following options

interface SlackRunnerOptions {
  ciProvider: string;
  vcsRoot: string;
  reportDir: string;
  videoDir: string;
  screenshotDir: string;
  customUrl?: string;
  onlyFailed?: boolean;
}

And will return a Slack IncomingWebhookResult.
