Instance Method Details

#with_files(files_with_contents = {}) ⇒ Object

Specify the files you need to create in a hash. The keys of the hash represent the file path and the value represents it’s content. Examples:

  • dir/a file’ => ‘content’ creates the ‘a dir’ directory containing an ‘a file’ file which content is ‘content’.

  • dir/’ => ” creates an empty ‘another dir’ directory. The value must be an empty string.

Optionally you can specify a different base directory (other than the default tmp) to use as a base directory. Example:

  • ‘stylesheets’, ‘file.txt’ => “” will create the file.txt file inside the existent stylesheets directory. The stylesheets directory won’t be deleted
