 # Tests
 
-## Why to run tests
-
-Running tests will make sure that crew is working correctly or explain the problem if it's not.
-
-## When to run tests
-
-The tests can be used at any time to help with development but make sure to run them before submitting a Pull Request.
-
-## Preparing new tests
-
-To prepare a new test, create a ruby script. It may use crew constants (created in `lib/const.rb`) and import packages (be sure to use `require_relative`).
-
-It should finish normally if the test passed, otherwise abort with `exit 1` and preferably explain why the test failed.
-
-A simple example of a test script called `my_test` is below:
-
-```ruby
-#!/usr/bin/env ruby
-
-# Makes sure buildessential package depends on gcc
-require_relative "../lib/package"
-
-pkg = Package.load_package('../package/buildessential.rb')
-
-if pkg.dependencies and pkg.dependencies.has_key?('gcc') then
-    puts "Everything works properly.".lightgreen
-else
-    puts "Buildessential should depend on gcc!".lightred
-    exit 1
-end
-```
-Make sure the script is executable with `chmod +x my_test`. Note: This will only work in directories with execute permission.
-
-## How to run tests
-
-Execute `ruby my_test` from this directory (`tests/`). If all tests pass, it should display a message similar to `All tests successful.`, otherwise it should indicate what went wrong.
-
-Running tests manually may not work!
+These are a collection of programs used to ensure crew is working correctly.
+They **must** be run in this directory, otherwise they will result in false positives.
