如何测试一个块是否被屈服? [英] How to test that a block was yielded to?

问题描述

我有一个测试需要检查是否正在调用提供给方法的块.

I have a test which needs to check if a block given to a method is being called.

block = lambda { 
    #some stuff 
}
block.should_receive(:call)

get_data_with_timeout(1, &block)

def get_data_with_timeout(timeout)
    begin
        timeout(timeout) {
            data = get_data
            yield data #do stuff
        }
    rescue Timeout::Error
        #timeout!
    end
end

基本上我想检查一下，如果没有超时，则块正在被调用，反之亦然.这在 rspec 中可能吗?

Essentially I want to check that if there is no timeout then the block is being called and visa versa. Is this possible in rspec?

推荐答案

我常用的一种模式:

block_called = false
get_data_with_timeout(1) do
    block_called = true
end
block_called.should be_true
