Rspec testing cheatsheet

Precaution

  • Example groups are executed in random orders so setting let must be taken care of
  • before(:all) does not rollback transaction! Test data created remains in the test database! However, running rspec (on cmd line) will clear the test database.
    rake db:test:prepare will also clear the test database.

Testing samples:

The difference between XYZ and TMS tiles and how to convert between them

The difference between XYZ and TMS tiles and how to convert between them

Lots of tile-based maps use either the XYZ or TMS scheme. These are the maps that have tiles ending in /0/0/0.png or something. Sometimes if it's a script, it'll look like &z=0&y=0&x=0 instead. Anyway, these are usually maps in Spherical Mercator.

Good examples are OpenStreetMap, Google Maps, MapBox, MapQuest, etc. Lots of maps.

Most of those are in XYZ. The best documentation for that is slippy map tilenames on the OSM Wiki, and Klokan's Tiles a la Google.

Read keypresses from user in terminal, including arrow keys using pure Ruby. This has since been folded into a much more robust gem called Remedy. https://rubygems.org/gems/remedy & https://github.com/acook/remedy
