In this episode we dive into the world of troubleshooting and debugging exploring different methodologies and tools that should help you take out any pesky bugs you might come across.
Segment 1 - Troubleshooting Methodologies
Process of Elimination
Slowly eliminate parts of your code that might be the culprit
Narrow down the culprit then perform the process of elimination on the section that is causing the issue
Don't be afraid to Google/research
Researching is nothing to be ashamed of, it does not mean you don't know what you're doing
As you look things up you'll be enhancing your researching skills, which is helpful when treading into new technologies
Learn the Source
Don't just bandaid the issue
Find out the who, what, where, when, why, and how
Apply an actual fix to the issue wherever possible and take measure to prevent it from happening again
Segment 2 - Debugging in the Browser
UI/UX Debugging
Using console window on Google Chrome
Inspecting elements to determine proper positioning and check if something is overlapping
Primarily use: Elements View, Styles View, and Console
Using console.log to check how a program is running
Advanced Console Debugging
JS Breakpoints to check on parts of programs
Better than console logs in some more advanced cases
Can check all local variables at a select breakpoint
Postman for DB Debugging
Segment 3 - Application/Storytime
Troubleshooting Cordova Apps on Android
Longevity testing
Wireless adb debugging
Passing console logs through from webview to Android through an interface
Crashing issues
Media playback issues
VPN Gateway Failure (some details changed for security procedure
IT support issue
Establishing a tunnel worked but routing internally didn't work
Ended up being an NDP issue
Most advanced troubleshooting Matt has possibly done (most involved - over 2 weeks of work)
Web News - Experience Doesn't Trump Research
Don't shy away from research
We typically have the documentation of a given framework or library that we are using, pulled up on a tab at all times
Impossible to commit everything to memory
Getting muscle memory, intuition, and research skills down pat makes you a proper "technician" for software engineering and IT work
