What You Will Learn
- How to debug your applications and the work of others
- How to add instrumentation to your code to assist debugging by you and others
- How to use and leverage the built in instrumentation of APEX
- Techniques for efficiently discovering the source of defects
- Techniques for creating repeatable processes to speed the time of discovery, test, and retest
- How to create remote debugging capabilities to gather information from production
Requirements
Working knowledge of Oracle APEX, equivalent to the knowledge gained in our Introduction to APEX class plus 3 to 6 months of actual APEX application development experience.
Description
Master Debugging in APEX: A Course for Experienced Developers
Dive deep into the world of debugging with this expert-level course designed for seasoned APEX professionals. Learn the essence of debugging in software development, and distinguish between server-side and client-side challenges. Gain proficiency in APEX developer tools, understand the Developer toolbar, use the APEX Debug API, and enhance your skills in adding custom data to logs.
Develop robust strategies for defining bugs, hypothesis-driven problem-solving, and creating testable scenarios. Hone your practical skills in code instrumentation, naming conventions, and variable usage. Explore advanced techniques in remote debugging and efficient defect discovery. Cap off your learning journey with Javascript debugging skills, equipping you with comprehensive expertise to tackle any debugging challenge in APEX.
This course focuses on finding “Programmer Errors”, not “Performance Problems”. Some of the tools we will use can help with Performance but that is not the focus on the class.
Technical Requirements
Nothing is required for labs (workshops). SkillBuilders will provide everything you need for all hands-on labs. Modest PC or Mac specs are required to connect to the online class. Detailed specs can be found here.
Also, we strongly recommend using two monitors for this class. This will allow to you to view the instructors display on one monitor and your code on the second.
