I have a ruby method written and I need to test it. Below is my method.
def iterate_each_doc
count=1
arr_of_doc = []
max_offset = 700
loop do
begin
feed_url = "http://www.example.com?q=&page=#{count}";
json_doc = JSON.parse(page)
jsons_rec = get_json_rec(json_doc)
if jsons_rec.size > 0
arr_of_doc += jsons_rec
end
count += 1
break if json_doc["list"].empty? && offset > json_doc["lastPage"]
rescue
catch exception
end
end
arr_of_doc
end
I tested the return value of the method as below
it "should fetch from json document and return an array of videos
containing only full episodes" do
stub_request(:get, url).to_return(status: 200, :body =>
File.read(File.join(json_saved_pages_path, 'sample.json')))
result = subject.iterate_each_doc
result.should_not be_empty
result.size == 3
end
But I need to make sure that the loop executes without any fail and
breaks only till it satisfies the condition
i.e.
if json_doc["list"].empty? && offset > json_doc["lastPage"]
This condition will satisfy till lastpage of the json doc is 700. But
in my rspec I cannot allow to execute the loop everytime till the
condition. So what would be the best way to achieve this. Please help.
