# codeceptjs-cmdhelper
[](https://badge.fury.io/js/codeceptjs-cmdhelper)
[](https://npmjs.org/package/codeceptjs-cmdhelper)
> Let your CodeceptJS tests run commands in the console/terminal
This is a [Helper](https://codecept.io/helpers/) for [CodeceptJS](https://codecept.io/) that allows you to run commands in the console/terminal. **It is especially useful for preparing the execution environment before/after executing test cases.**
👉 It works with CodeceptJS 1, 2, and 3.
## Install
```bash
npm i -D codeceptjs-cmdhelper
```
## Configure
In your configuration file (_e.g._, `codecept.conf.js`, `codecept.json`), include **CmdHelper** in the property **helpers** :
```js
...
"helpers": {
...
"CmdHelper": {
"require": "./node_modules/codeceptjs-cmdhelper"
}
},
...
```
### Options
Optionally, you can set an `options` property with an object that accepts the same parameters as [NodeJS spawn](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options)'s, plus `showOutput: boolean`. The default value is `{ shell: true, showOutput: true }`.
Example:
```js
...
"helpers": {
...
"CmdHelper": {
"require": "./node_modules/codeceptjs-cmdhelper",
"options": {
"showOutput": false
},
}
},
...
```
## Usage
### Syntax differences between CodeceptJS 2 and CodeceptJS 3
In CodeceptJS 2, your callbacks receive `I` as argument:
```javascript
Scenario('test something', async ( I ) => { // CodeceptJS 2 notation
/* ... */
} );
```
In CodeceptJS 3, your callbacks receive an object with `I` - that is, `{ I }`:
```javascript
Scenario('test something', async ( { I } ) => { // CodeceptJS 3 notation
/* ... */
} );
```
See the [CodeceptJS docs](https://github.com/codeceptjs/CodeceptJS/wiki/Upgrading-to-CodeceptJS-3) for more information on how to upgrade your codebase.
### Examples
> The following examples are written with **CodeceptJS 3**.
Now the object `I` (of your callbacks) has [new methods](#api).
#### Example 1
```js
BeforeSuite( async ( { I } ) => {
await I.runCommand( 'echo "Hello world!" >foo.txt' );
} );
AfterSuite( async ( { I } ) => {
await I.runCommand( 'rm foo.txt' );
// await I.runCommand( 'del foo.txt' ); // on Windows
} );
// ... your feature ...
// ... your scenarios ...
```
#### Example 2
```js
Feature( 'Foo' );
Scenario( 'Bar', async ( { I } ) => {
await I.runCommand( 'mkdir foo' );
await I.runCommand( 'mkdir bar', { showOutput: false } );
} );
```
### Note
Make sure to handle errors properly, with `try`..`catch`.
```js
try {
const code = await I.runCommand( 'mkdir foo' );
console.log( 0 === code ? 'success' : 'some problem occurred' );
} catch ( e ) {
console.warn( e );
}
```
## API
```js
/**
* Executes the given command.
*
* @param {string} command Command to execute.
* @param {object} [options] Same options as in NodeJS' spawn(), plus `showOutput: boolean`. Optional. Default is `{ shell: true, showOutput: true }`.
*
* @returns {Promise< number >} Promise with the returning execution status code (0 means success).
*/
runCommand( command, options )
```
