It’s also useful when the upfront cost of configuration is worth the time.
It’s ideal for large teams worried that debugging code will make it into production. However, debugging with Visual Studio Code also has the largest and most complex setup configuration. Examples of these toolchains include using Java with Eclipse or C# with Visual Studio. This option appeals to those developers with a bias toward a specific toolchain and an integrated development environment (IDE). It’s the option I use for most of my projects, and others often ask me for the same setup. In debug mode, this application has the best layout of information as well as the smallest learning curve. The rest of this post will focus on debugging using Visual Studio Code, a text editor created by Microsoft. The best solution is the one that you’re most productive in. If you’re working on a large team, using a text editor or IDE and ruby-debug-idewould be a good choice. For a solo project or small team, using puts and inspect may be the quickest solution for a one-off problem. Which debugging tool you choose depends on the problem you’re trying to solve and your personal preference.
The best place to start your investigation is at the point the error was first discovered. The best place to start your investigation One such APM, Retrace, reports all errors as they occur, along with a stack trace and any related logging.
It often causes a different issue or accelerated software rot.Ī good way to find errors fast is to use an application performance management tool (APM). I’ve made this mistake many times, so I can tell you from experience not to do this. Under pressure, you may be tempted to provide a quick fix for the effect rather than the cause, without understanding the purpose of the code. When you find errors early, your users may not notice that the error occurred, which gives you more time to determine the root cause and fix the issue.
Finding errors before your users doįinding production errors before your users report them gives you some time to think calmly about the solution. Gene Kranz at his console on May 30, 1965, in the Mission Operations Control Room, Mission Control Center, Houston. We can use Kranz’s simple, yet important, strategy when we approach debugging a Ruby application.
Let’s not make things worse by guessing.” Gene Kranz, director of the mission control team that saved Apollo 13, sums up their approach to problem-solving when he said, “Let’s work the problem, people. An example of a high-performance team that often needs to find the root cause of a serious issue under pressure is the mission control team at NASA.
