+description: Create custom reporters.
+title: Third party reporters
+---
+
+Mocha 1.3.0 allows you to define custom third-party reporters within your own test suite, or by using npm modules. For example if "lcov-reporter" was published to npm, you would simply add it to your package.json in `devDependencies` and use `--reporter lcov-reporter`.
+
+Here is a minimalistic sample reporter, which you can use by executing: `mocha --reporter my-reporter.js`
+
+```js
+// my-reporter.js
+var mocha = require('mocha');
+module.exports = MyReporter;
+
+function MyReporter(runner) {
+  mocha.reporters.Base.call(this, runner);
+  var passes = 0;
+  var failures = 0;
+
+  runner.on('pass', function (test) {
+    passes++;
+    console.log('pass: %s', test.fullTitle());
+  });
+
+  runner.on('fail', function (test, err) {
+    failures++;
+    console.log('fail: %s -- error: %s', test.fullTitle(), err.message);
+  });
+
+  runner.on('end', function () {
+    console.log('end: %d/%d', passes, passes + failures);
+  });
+}
+
+// To have this reporter "extend" a built-in reporter uncomment the following line:
+// mocha.utils.inherits(MyReporter, mocha.reporters.Spec);
+```
+
+For details look at the implementations in [lib/reporters/*](https://github.com/mochajs/mocha/tree/main/lib/reporters).
+
+Another sample implementation can be found at [mocha-examples: third-party-reporter (GitHub)](https://github.com/mochajs/mocha-examples/tree/main/packages/third-party-reporter).
+
+Mocha provides the following events:
+- **start**: Execution started
+- **waiting**: Execution of root `Suite` delayed
+- **ready**: Execution of root `Suite` started
+- **end**: Execution complete
+- **suite**: Test suite execution started
+- **suite end**: All tests (and sub-suites) have finished
+- **test**: Test execution started
+- **test end**: Test completed
+- **hook**: Hook execution started
+- **hook end**: Hook complete
+- **pass**: Test passed
+- **fail**: Test failed
+- **pending**: Test pending
+- **retry**: Test failed and retries
