The pitch goes like this:
A good developer is a lazy developer. Stop making dummy test entries by hand. Use Seed to make them for you.
Dummy entries are annoying and I know you know I know you know that I hate to create them manually. Earlier this year I was building a simple CMS with Ruby on Rails and was delighted to see the seed data functionality.
For ExpressionEngine we have Seed (by Joel Bradbury). It lets you configure how the seed data is populated based on conditions you set. You tell Seed the channel you want to populate and how many entries. You can then set some populate options.
Wonderful add-on. It’s free, so go get it now.
