// here we setup mock calls
\Mezon\Conf\Conf::setConfigStringValue('fs/layer', 'mock');

// here we setup that mock will return true if the we check that this directory exists
\Mezon\Fs\Layer::$createdDirectories[] = [
	'path' => 'path-to-existing-directory'

// here we will get true
var_dump(\Mezon\Fs\Layer::directoryExists('path-to-existing-directory'));

// and here we will get false
var_dump(\Mezon\Fs\Layer::directoryExists('path-to-unexisting-directory'));

// here we setup mock calls
Conf::setConfigStringValue('console/layer', 'mock');

// setup values wich will be returned by the method Mezon\Console\Layer::readline()
\Mezon\Console\Layer::$readlines[] = 'line 1';

// read lines
// note that native php method `readline` will noe be called
// just returning value of the Mezon\Console\Layer::$readlines array
echo \Mezon\Console\Layer::readline(); // ouputs 'line 1'
echo \Mezon\Console\Layer::readline(); // ouputs 'line 2'

// here we setup native php methods calls
Conf::setConfigStringValue('console/layer', 'real');
echo \Mezon\Console\Layer::readline(); // outputs string wich you will input in the console
// because in this line real method `readline` will be called

// here we setup mock calls
Conf::setConfigStringValue('fs/layer', 'mock');

// writing file
\Mezon\Fs\Layer::filePutContents('file-path', 'data', FILE_APPEND);
// ^^^ but in this call all file content will be stored into memory, not on disk
// on production this call works like file_put_contents

// creating directory

// ^^^ real directory also is not created

// checking if the directory exists
