我猜这与Rake读取文件一次而不是倒带有关吗？但是,我不确定.有任何想法吗？
require 'rake'
require 'rails_helper'
describe 'MyRakeTask' do
before(:all) do
Rails.application.load_tasks
end
it 'does something sweet' do
Rake::Task["namespace:my_task"].invoke # runs task
end
it 'but it doesnt do it again' do
Rake::Task["namespace:my_task"].invoke # returns nil
end
end
