我们在rails项目中使用RSpec进行单元测试.我想在RSpec中设置一些性能测试,但这样做是为了不破坏“常规”功能和固定装置.
理想情况下,我能够以某种方式标记我的性能规格,以便它们不会默认运行.
然后,当我明确指定运行这些规范时,它将加载一组不同的灯具(使用更大,更像’类似生产’的数据集进行性能测试是有意义的.
这可能吗？看起来应该是这样.
有没有人设置这样的东西？你是怎么做到的？
解决方法
我设法通过以下方式获得了我想要的东西：
# Exclude :performance tagged specs by default
config.filter_run_excluding :performance => true
# When we're running a performance test load the test fixures:
config.before(:all,:performance => true) do
# load performance fixtures
require 'active_record/fixtures'
ActiveRecord::Fixtures.reset_cache
ActiveRecord::Fixtures.create_fixtures('spec/perf_fixtures',File.basename("products.yml",'.*'))
ActiveRecord::Fixtures.create_fixtures('spec/perf_fixtures',File.basename("ingredients.yml",'.*'))
end
# define an rspec helper for takes_less_than
require 'benchmark'
RSpec::Matchers.define :take_less_than do |n|
chain :seconds do; end
match do |block|
@elapsed = Benchmark.realtime do
block.call
end
@elapsed <= n
end
end
# example of a performance test
describe Api::ProductsController,"API Products controller",:performance do
it "should fetch all the products reasonably quickly" do
expect do
get :index,:format => :json
end.to take_less_than(60).seconds
end
end
但我倾向于同意Marnen的观点,即这不是性能测试的最佳选择.
