# After Run Event

The `after:run` event fires after a run is finished. When running cypress via
`cypress open`, the event will fire when closing a project.

When running via `cypress run`, the event will fire each time `cypress run`
executes. As a result, if running your specs in
[parallel](/llm/markdown/cloud/features/smart-orchestration/parallelization.md), the event will
fire once for each machine on which `cypress run` is called.

## Syntax

⚠️ This code is part of the
[setupNodeEvents](/llm/markdown/app/plugins/plugins-guide.md#Using-a-plugin) function and
thus executes in the Node environment. You cannot call `Cypress` or `cy`
commands in this function, but you do have the direct access to the file system
and the rest of the operating system.

⚠️ When running via `cypress open`, the `after:run` event only fires if the
[experimentalInteractiveRunEvents flag](/llm/markdown/app/references/configuration.md#Experiments)
is enabled.

```ts
on('after:run', (results) => {
  /* ... */
})
```

 **results *(Object)***

Results of the run, including the total number of passes/failures/etc, the
project config, and details about the browser and system. It is the same as the
results object resolved by the [Module API](/llm/markdown/app/references/module-api.md#Results).

Results are only provided when running via `cypress run`. When running via
`cypress open`, the results will be undefined.

## Usage

You can return a promise from the `after:run` event handler and it will be
awaited before Cypress proceeds running your specs.

### Log the number of passed tests of a run

```ts
on('after:run', (results) => {
  // results will look something like this when run via `cypress run`:
  // {
  //   totalDuration: 81,
  //   totalSuites: 0,
  //   totalTests: 1,
  //   totalFailed: 0,
  //   totalPassed: 1,
  //   totalPending: 0,
  //   totalSkipped: 0,
  //   browserName: 'electron',
  //   browserVersion: '59.0.3071.115',
  //   osName: 'darwin',
  //   osVersion: '16.7.0',
  //   cypressVersion: '3.1.0',
  //   config: {
  //     projectId: '1qv3w7',
  //     baseUrl: 'http://example.com',
  //     viewportWidth: 1000,
  //     viewportHeight: 660,
  //     // ... more properties...
  //   }
  //   // ... more properties...
  //   }
  // }
  if (results) {
    // results will be undefined in interactive mode
    console.log(results.totalPassed, 'out of', results.totalTests, 'passed')
  }
})
```
