The best feature about deep source was its ability to highlight coding errors in our C# applications without any manual intervention, which really helped us save time and effort during application development. It also provided detailed information of all possible issues with every line of codes written by me or my colleagues. I found it difficult for an inexperienced person like myself to use this software effectively. Although I had some training classes from their support team regarding how to use the product but still there are certain functions that are not clearly explained. I have been using this for more than 1 year now and i am satisfied so far with what they provide. Our main concern while working at client side was to get as many bugs fixed quickly before going live. We used to do manual testing and fixing them after deployment manually, however we realized the benefit of having automation tests when done right.
