Mocha Stackdriver Reporter

Mocha reporter using the Google Cloud Logging API.

Install

npm install mocha-stackdriver-reporter --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.

CLI

Run mocha with reporter configured:

mocha --reporter mocha-stackdriver-reporter --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 --reporter-options projectId=my-project-id,logName=my-log-name

Code

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

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",
    },
  },

  onlyConsole: false, // (optional) if true, only output result to console
});
