I am working on Scrapy 0.20 with Python 2.7. I found PyCharm has a good Python debugger. I want to test my Scrapy spiders using it. Anyone knows how to do that please?
File->Setting->Project structure->Add content root. But I don't know what else I have to do

In PyCharm debugger, you can preview int variables in the hexadecimal or binary format. This might be particularly helpful when you debug network scripts that include binary protocols.
Start Scrapy Shell from your Spider Code shell. inspect_response method in your spider code. This will open a Scrapy shell session that will let you interact with the current response object. from scrapy.
Just right-click any line in the editor and select the Debug <filename> command from the context menu. After the program has been suspended, use the debugger to get the information about the state of the program and how it changes during running.
The scrapy command is a python script which means you can start it from inside PyCharm.
When you examine the scrapy binary (which scrapy) you will notice that this is actually a python script:
#!/usr/bin/python from scrapy.cmdline import execute execute() This means that a command like scrapy crawl IcecatCrawler can also be executed like this: python /Library/Python/2.7/site-packages/scrapy/cmdline.py crawl IcecatCrawler
Try to find the scrapy.cmdline package. In my case the location was here: /Library/Python/2.7/site-packages/scrapy/cmdline.py
Create a run/debug configuration inside PyCharm with that script as script. Fill the script parameters with the scrapy command and spider. In this case crawl IcecatCrawler.
Like this: 
Put your breakpoints anywhere in your crawling code and it should work™.
