JEST test generator for NEST JS Apps-AI-generated JEST test plans.

Example

After analyzing a NESTJS class like `UsersService`, the generator will identify all public methods such as `findAll`, `createUser`, or `deleteUser`. It will then propose a test plan that outlines specific scenarios, including successful and failure cases.

Scenario

In a real-world scenario, a NESTJS service that interacts with an external API to fetch user data would have its test cases automatically generated. The tool ensures that edge cases like empty responses, invalid data, or network failures are considered in the generated tests.

Example

For a NESTJS service using an external database like MongoDB or an external library like Axios, the JEST test generator will mock these dependencies. This allows the tests to run in isolation, focusing on the business logic rather than the external dependencies.

Scenario

Imagine a NESTJS `ProductService` that fetches product data from a remote API. The generator would mock the API calls, ensuring that the tests validate the business logic without requiring the actual API to be up and running, enabling rapid testing.

Example

For a method that processes user input, like `updateUserProfile`, the test generator will create test cases covering valid input, invalid input (e.g., empty fields or incorrect formats), and exceptions thrown during the update operation.

Scenario

In a scenario where a NESTJS service allows users to update their profile, the test generator will create cases that handle both normal updates and scenarios like missing required fields, ensuring that each edge case is thoroughly tested.
