How do I effectively force Minitest to run my tests in order?

Question

I know. This is discouraged. For reasons I won\'t get into, I need to run my tests in the order they are written. According to the documentation, if my test class (we\'ll c

The best way to interfere in this chain may be to override a class method runnable_methods:

def self.runnable_methods
  ['run_first'] | super | ['run_last']
end

#Minitest version:
def self.runnable_methods
  methods = methods_matching(/^test_/)

  case self.test_order
  when :random, :parallel then
    max = methods.size
    methods.sort.sort_by { rand max }
  when :alpha, :sorted then
    methods.sort
  else
    raise "Unknown test_order: #{self.test_order.inspect}"
  end
end

You can reorder test any suitable way around. If you define your special ordered tests with

test 'some special ordered test' do 
end

, don't forget to remove them from the results of super call.

In my example I need to be sure only in one particular test to run last, so I keep random order on whole suite and place 'run_last' at the end of it.
