  • 3 different environments: development, staging, production
  • Write migrations for schema changes
  • Use ORM if possible over raw queries
  • Always make it possible for testers to report the version they tested against
    • Simplest is to have a meta field in the head section

  • Mockups
  • SRS
  • Database and software architecture
  • Implementation
  • Test/QA
  • Deployment

Writing tests

Software development Processes

When joining a new project without tests, here is the value you need to provide through the addition of tests:

  1. the application works and doesn't crash
  2. the application works and supports a few input cases
  3. the application works and supports a variety of input cases
  4. the application works and is robust to most input cases
  • Write a test that tests the common case usage of your function
  • Write tests that cover edge cases of your function
  • Write tests to cover all statements, branches, paths

games

An initial seed is computed and stored in the game save file
Based on this seed, the world is pseudo randomly computed, using a certain chunk/block/tile size (e.g., 32x32, 128x128)
The world map is only generated on-demand, that is, as far as the player can see
When a new chunk is discovered, its blocks are computed and persisted in the save file
If there are no active components in a chunk that is not visible, the game will obviously not render it, it will only simulate it (position, item, velocity, etc)
Certain thing, for instance alien types and alien base size, may only be computed once they are observed. At first, maybe only a location anchor will exist to indicate where they should spawn, but the rest will be generated only when needed.
