make full code for real world testing

Certainly! However, to provide you with a complete code that is suitable for real-world testing, I'd need a bit more information about your specific needs. Here are a few clarifications that would help:

**Programming Language:** Which programming language are you working with? (e.g., Python, Java, JavaScript, etc.)
**Type of Application:** What kind of project or application do you have in mind? (e.g., web app, machine learning model, mobile app, etc.)
**Testing Framework:** Are you seeking to implement unit tests, integration tests, or system tests? If you have a specific testing framework in mind (like PyTest for Python, JUnit for Java, etc.), please specify.
**Dependencies:** Are there any specific libraries or frameworks that you're using that should be included in the testing code?
**Specific Functionality:** What specific components or functions do you want to test?

Once you provide these details, I'll be able to assist you with a relevant and complete code example for your real-world testing needs!
