Master the art of writing effective prompts for debugging, testing, code generation, and more—boosting developer productivity and AI collaboration across the coding workflow.
Overview
Prompt Engineering for Code and Testing is a practical, skill-building course designed for developers, testers, and technical professionals who want to use AI effectively in software workflows. As AI tools like ChatGPT, Copilot, and Gemini become integral to modern development, knowing how to write effective prompts has become a crucial skill. This course guides you through the core principles of prompt design—covering clarity, accuracy, specificity, and structure—to help you generate clean code, explain complex logic, and even create test cases with ease.
The course moves beyond basic prompt writing. You'll explore how to debug and rewrite ineffective prompts, assess their output using scoring rubrics and feedback loops, and optimize them for different audiences and formats. Real-world coding examples are used throughout the course to demonstrate how prompts can be tuned for test generation, bug fixing, and code documentation. You’ll also learn how to catch hallucinations, manage bias, and verify the reliability of AI-generated outputs.
By the end of the course, you’ll know how to build your own prompt libraries, version prompts effectively, and perform A/B testing to compare prompt variants. Whether you're using AI to accelerate development or streamline testing, this course offers a structured framework and toolkit for becoming a confident, capable prompt engineer in the software domain.
