// Create some data...
var data = new Array( 1000 );
for ( var i = 0; i < data.length; i++ ) {
    data[ i ] = Math.random();
}
 
// Create a readable stream:
var readStream = eventStream.readArray( data );
 
// Create a new count stream:
var stream = cStream().stream();
 
// Create a pipeline:
readStream.pipe( stream )
    .pipe( eventStream.map( function( d, clbk ) {
        clbk( null, d.toString() )
    }))
    .pipe( process.stdout );

Tests

Unit tests use the Mocha test framework with Chai assertions.

Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:

$ mocha

All new feature development should have corresponding unit tests to validate correct functionality.
