Configuring reporters

Set the reporters configuration using --reporter-options configFile=config.json.

• Include reporters in reporterEnabled as a comma-delimited list

  {
      "reporterEnabled": "spec, @my-org/custom"
  }

• Specify each reporter's configuration using its camel-cased name, followed by reporterOptions, as key.

  For scoped reporters such as example @myorg/custom, remove all special characters.

  {
      "reporterEnabled": "spec, @my-org/custom",
      "myOrgCustomReporterOptions": {
          // [...]
      }
  }

Examples:

• Generate spec and json reports.

// File: config.json
{
    "reporterEnabled": "spec, json"
}

$ ./node_modules/.bin/mocha --reporter mocha-multi-reporters --reporter-options configFile=config.json
  mocha-test #1
    ✓ sample test #1.1
    ✓ sample test #1.2

  mocha-test #2
    ✓ sample test #2.1
    - sample test #2.2

• Generate tap and xunit reports.

// File: config.json
{
    "reporterEnabled": "tap, xunit",
    "xunitReporterOptions": {
        "output": "xunit-custom.xml"
    }
}

$ ./node_modules/.bin/mocha --reporter mocha-multi-reporters --reporter-options configFile=config.json

1..4
ok 1 mocha-test 1 sample test 1.1
ok 2 mocha-test 1 sample test 1.2
ok 3 mocha-test 2 sample test 2.1
ok 4 mocha-test 2 sample test 2.2 # SKIP -
# tests 3
# pass 3
# fail 0

$ cat xunit-custom.xml
<testsuite name="Mocha Tests" tests="4" failures="0" errors="0" skipped="1" timestamp="Sun, 03 Jan 2016 08:02:24 GMT" time="0.006">
<testcase classname="mocha-test #1" name="sample test #1.1" time="0.001"/>
<testcase classname="mocha-test #1" name="sample test #1.2" time="0.001"/>
<testcase classname="mocha-test #2" name="sample test #2.1" time="0"/>
<testcase classname="mocha-test #2" name="sample test #2.2" time="0"><skipped/></testcase>
</testsuite>

• Generate tap and junit reports.

To generate junit report, we are using mocha-junit-reporter.

$ npm install mocha-junit-reporter

// File: config.json
{
    "reporterEnabled": "mocha-junit-reporter",
    "mochaJunitReporterReporterOptions": {
	    "mochaFile": "junit-custom.xml"
    }
}

$ ./node_modules/.bin/mocha --reporter mocha-multi-reporters --reporter-options configFile=config.json

1..4
ok 1 mocha-test 1 sample test 1.1
ok 2 mocha-test 1 sample test 1.2
ok 3 mocha-test 2 sample test 2.1
ok 4 mocha-test 2 sample test 2.2 # SKIP -
# tests 3
# pass 3
# fail 0

$ cat xunit-custom.xml
<?xml version="1.0" encoding="UTF-8"?>
<testsuites name="Mocha Tests" time="0.001" tests="4" failures="0" skipped="1">

cmrOutput option

This option lets you dynamically replace the output files of reporter options.

In your Mocha --reporterOptions, specify cmrOutput with a plug-sign-separated list of the reporter name, the property on that reporter's options to have replaced, and the dynamic ID you would like substituted. If you need multiple reporters to have dynamic output, add additional plus-sign-separated lists separated by colons.

mocha --reporter mocha-multi-reporters --reporterOptions configFile=mocha-multi-reporters.json,cmrOutput=@mochajs/json-file-reporter+output+specialID tests

// mocha-multi-reporters.json
{
  "mochajsJsonFileReporterReporterOptions": {
    "output": "tests/results/file-{id}.json"
  },
  "reporterEnabled": "spec, @mochajs/json-file-reporter"
}

This will produce an output for @mochajs/json-file-reporter reporterOptions with the value:

tests/results/file-specialID.json

Programmatic

Note that when Mocha is called programmatically, it is passed an options object when created. This object is usually derived from a config file that your mocha test runner reads prior to instantiation. This is the object that must contain a key reporter with a value of mocha-multi-reporters for this plugin to be used. You can also pass the key reporterOptions with a value of any of the above listed config files (including the reporterEnabled subkey and any other plugin configuration information.) This removes the requirement to have an intermediate configuration file specifically for the multireporter configuration.

const mocha = new Mocha({
      reporter: "mocha-multi-reporters",
      timeout: config.testTimeout || 60000,
      slow: config.slow || 10000,
      reporterOptions: {
          "reporterEnabled": "mocha-junit-reporter, tap",
          "mochaJunitReporterReporterOptions": {
              "mochaFile": "junit-custom.xml"
          }
      }
    });
    mocha.addFile(...)
    mocha.run(...)

Note that it will first check if reporterOptions contains a configFile key, and if it does, use that. That key must not exist in the reporterOptions object in order to pass these values in directly.
