Mocha Stackdriver Reporter w/ Stats

Mocha reporter using the Google Cloud Logging API with additional stats.

Originally a fork of mocha-stackdriver-reporter and full credit to the original author, whose work I have and will continue to build on.

Note: this was developed for usage with Cypress, so YMMV.

Install

npm install mocha-stackdriver-reporter-stats --save-dev

Options

  • projectId: Google Cloud Project ID.
  • logName: Log identifier; gets merged with projectId into e.g. projects/test123/logs/my-function%2Fwith-name. Note how last part is URL encoded. This is automatically taken care when using a logName with / in the name, e.g. my-function/with-name.
  • entryMetadata: Metadata for log entries.
  • stats: An array of which of the stats from Mocha's stats collector you wish to include (if not specified, it will return all of them)
  • alsoConsole || onlyConsole || alsoFile || onlyFile: Write output to/only to console or file (file includes all data from the reporter config for Stackdriver logging)
  • noCloud: For when you're testing, or if you want to run this with onlyFile/alsoFile and combined with the mocha-stackdriver-merge module to report all tests (and not just a single spec) back jointly (inspired by mochawesome-merge )

CLI

Run mocha with reporter configured:

mocha --reporter mocha-stackdriver-reporter-stats --reporter-options projectId=myGcpProjectId,logName=myLogName

Entry metadata can be set with environment variable ENTRY_METADATA:

ENTRY_METADATA='{ "resource": { "labels": { "function_name": "my-cloud-function", "project_id": "my-project-id", "region": "my-region" }, "type": "cloud_function" } }' \
mocha --reporter mocha-stackdriver-reporter-stats --reporter-options projectId=my-project-id,logName=my-log-name

Code

const Mocha = require("mocha");
const StackdriverReporter = require("mocha-stackdriver-reporter-stats");

const mocha = new Mocha();

mocha.reporter(StackdriverReporter, {
  projectId: "my-project-id",
  logName: "my-log-name",
  entryMetadata: {
    resource: {
      labels: {
        function_name: "my-cloud-function",
        project_id: "my-project-id",
        region: "my-region",
      },
      type: "cloud_function",
    },
  },
  stats: ["suites", "tests", "passes", "pending", "failures", "start", "end", "duration"],
  alsoConsole: false, // (optional) if true, also output result to console
  onlyConsole: false, // (optional) if true, only output result to console
  alsoFile: false, // (optional) if true, also output result to file
  onlyFile: false, // (optional) if true, only output result to file (will be overridden by onlyConsole)
  reportDir: "reports/stackdriver-reporter", // This will not be created for you. Calling alsoFile or onlyFile without this option will result in an error on reporting
  noCloud: false // (optional) if true, do not output results to Stackdriver
});
