Use case: Generate test cases

You can use Gemini Enterprise to generate test cases.

Example prompt

In the chat box, enter a prompt such as the following:

Can you generate a comprehensive set of unit tests for this function, covering
both edge cases and normal scenarios? Also, can you help me create a mock
object for this external dependency?

Example output

In response to this prompt, Gemini Enterprise produces output similar to the following:

Of course! I can help with that. Unit testing is crucial for ensuring your code is reliable, and mocking external dependencies is a key part of that process.

Below is a comprehensive set of unit tests for your is_user_eligible_for_promo function. I've used Python's built-in unittest library to create the test suite and unittest.mock to create a mock object for the UserDatabase.

Mocking the External Dependency

First, let's talk about the mock object. We need to isolate the function we are testing (is_user_eligible_for_promo) from its external dependency (UserDatabase). By creating a mock, we can simulate the behavior of the database in a controlled way, allowing us to test how our function reacts to different scenarios without making actual database calls.

The Unit Test Suite

Here is the complete file, including the original code, the mock implementation, and a comprehensive set of unit tests covering normal and edge cases.
