🚩 Looking for another real-world demonstration of Cypress in action? Check out the Cypress Real World App repository.

Conduit App

Fork of applitools/cypress-applitools-webinar which is a fork of gothinkster/realworld "Conduit" blogging application.

Tests

The tests are in cypress/integration folder

• feeds-spec.js shows how to check the favorite articles feed and the global feed
• follow-user-spec.js shows how to create two users and check if one user can follow the other
• login-spec.js checks if the user can log in via UI and via API
• new-post-spec.js verifies that a new article can be published and updated
• profile-spec.js lets the user edit their profile
• register-spec.js tests if a new user can register
• tags-spec.js checks if tags work
• pagination-spec.js creates many articles via API calls and then checks if they are displayed across two pages
• force-logout-spec.js verifies that unauthorized API calls force the user session to finish

Full code coverage

Front- and back-end coverage for this application is collected using the @cypress/code-coverage plugin. You can run the locally instrumented server and client using npm run dev:coverage command. The backend coverage is exposed in server/server/index.js via endpoint listed in cypress.json (usually GET /__coverage). The frontend coverage is collected by instrumenting the web application source code on the fly, see the client/.babelrc file.

The combined report is saved in coverage/index.html after the tests finish:

The coverage is sent to Coveralls.io using command npm run coveralls from CircleCI AFTER partial coverage information from parallel E2E test runs is combined, see circle.yml file.

Combining code coverage from parallel runs

If you do not use an external code coverage service for combining code coverage reports, you need to combine those reports yourself like this repository is showing in circle.yml file. Several E2E cypress/run jobs run in parallel, each job saving its own coverage report folder. Then every job copies the report (using save-partial-coverage-report command) into a unique folder to avoid overwriting via reports from other machines. When all E2E jobs are finished, and reports are copied together, then the CI calls a command to merge the reports (see the merge-coverage-reports command that uses nyc merge tool).
