# node-mock-stdin
[](https://travis-ci.org/caitp/node-mock-stdin) [](https://coveralls.io/r/caitp/node-mock-stdin?branch=master) [](https://www.npmjs.org/package/mock-stdin)
Provide a mock readable stream, useful for testing interactive CLI applications.
Maybe simple mocks for other standard files wouldn't be a terrible idea, if anyone
feels like those are needed. Patches welcome.
## API
- **Module**
- [stdin()](#modulestdin)
- **MockSTDIN**
- [send()](#mockstdinsenddata-encoding)
- [end()](#mockstdinend)
- [restore()](#mockstdinrestore)
- [reset()](#mockstdinresetremovelisteners)
---
### Module.stdin()
**example**
```js
require('mock-stdin').stdin();
```
Replaces the existing `process.stdin` value with a mock object exposing a `send` method (a
`MockSTDIN` instance). This allows APIs like `process.openStdin()` or `process.stdin.on()`
to operate on a mock instance.
**note**: Event listeners from the original `process.stdin` instance are not added to the
mock instance. Installation of the mock should occur before any event listeners are
registered.
**return value**: A `MockSTDIN` instance
---
### MockSTDIN.send(data, encoding)
**example**
```js
var stdin = require('mock-stdin').stdin();
stdin.send("Some text", "ascii");
stdin.send(Buffer("Some text", "Some optional encoding"));
stdin.send([
"Array of lines",
" which are joined with a linefeed."
]);
// sending a null will trigger EOF and dispatch an 'end' event.
stdin.send(null);
```
Queue up data to be read by the stream. Results in data (and possibly end) events being
dispatched.
**parameters**
- `data`: A `String`, `Buffer`, `Array<String>`, or `null`. The `data` parameter will result in
the default encoding if specified as a string or array of strings.
- `encoding`: An optional encoding which is used when `data` is a `String`.
Node.js's internal Readable Stream will convert the specified encoding into the output
encoding, which is transcoded if necessary.
**return value**: The `MockSTDIN` instance, for chaining.
---
### MockSTDIN.end()
**example**
```js
var stdin = require('mock-stdin').stdin();
stdin.end();
```
Alias for [MockSTDIN.send(null)](#mockstdinsend). Results in dispatching an `end` event.
**return value**: The `MockSTDIN` instance, for chaining.
---
### MockSTDIN.restore()
**example**
```js
var stdin = require('mock-stdin').stdin();
// process.stdin is now a mock stream
stdin.restore();
// process.stdin is returned to its original state
```
Restore the target of the mocked stream. If only a single mock stream is created, will restore
the original `stdin` TTY stream. If multiple mock streams are created, it will restore the
stream which was active at the time the mock was created.
**return value**: The `MockSTDIN` instance, for chaining.
---
### MockSTDIN.reset(removeListeners)
**example**
```js
var stdin = require('mock-stdin').stdin();
stdin.end();
stdin.reset();
stdin.send("some data");
```
Ordinarily, a Readable stream will throw when attempting to push after an EOF. This routine will
reset the `ended` state of a Readable stream, preventing it from throwing post-EOF. This prevents
being required to re-create a mock STDIN instance during certain tests where a fresh stdin is
required.
If the `removeListeners` flag is set to `true`, all event listeners will also be reset. This is
useful in cases where you need to emulate restarting an entire application, without fully
re-creating the mock object.
**parameters**
- `removeListeners`: Boolean value which, when set to `true`, will remove all event listeners
attached to the stream.
**return value**: The `MockSTDIN` instance, for chaining.
