I would like to have a lab for creating theme

[Star Light]

I want to test theme before upload to Tumblr host. But I don't know how since theme using so much var of Tumblr. Don't we have any software for testing theme?

Nothing like that exists. The best way I found is:

• Link the CSS and JS files from your own remote server.
  
• Edit CSS and JS locally.
  
• On Save have both files be uploaded to your server. Some text editors have FTP plugins such as Notepad++ or SublimeText
  
• Refresh Tubmlr site to see changes.
  

It's either that or editing directly in Tumblr's edit panel

An option is to use local mapping in something like Charles proxy.

So in your theme HTML you add something like:

<link rel='stylesheet' href='http://fakedomain.com/style.css' type='text/css' media='all' /> Then in Charles you locally map http://fakedomain.com/style.css to c:\projects\tumblr\style.css, or where ever your file is.
