send-test-info

Attach unit test information to exceptions sent by Raven to Sentry

Read Connecting crash reporting with end to end tests

Install

Add this module to any project that uses Cypress for end to end testing and Raven.js client to send exceptions to Sentry.

npm install --save-dev send-test-info

Use

From any spec file, require and call a single function with the spec's filename.

const sendTestInfo = require('send-test-info')
// filename is optional
sendTestInfo({spec: __filename})
 
describe('Test page', function () {
  // unit tests
})

See example spec file cypress/integration/send-test-info-spec.js and the test page cypress/index.html

Result

Each exception captured by Raven and sent to Sentry will include the spec filename and the full test title.

Errors generated during end to end tests can be quickly triaged and recreated by just looking at the exception tags

API options

You can pass multiple options that control how many times it will search for Raven and add context. See cypress/integration/send-test-info-spec.js as an example.

sendTestInfo({
  spec: __filename,     // the name of the spec file
  maxCheckTimes: 10,    // how many times we should try finding Raven
  maxRavenInstalls: 1,  // how many times should we find Raven
                        // and keep looking again. Good if there are new pages
                        // loaded and Raven is installed again
  interval: 1000,       // interval (ms) between checks for Raven
  debug: true,          // print log messages to the console
  immediate: false,     // start searching for Raven immediately without
                        // using "beforeEach" callback. Good for setting up
                        // inside a Cypress command (like "login")
  breadcrumbs: false    // record Cypress commands as breadcrumbs (see below)
})

Cypress breadcrumbs

This module also subscribes to Cypress events using Cypress.on(...) syntax and adds the information to the Raven breadcrumbs. As the result, the exception will have very useful list of logical steps taken by the test before the crash.
