Jest Guru - Jest testing code generator.

Example

A function that adds two numbers.

Scenario

When a developer needs to ensure that their 'add' function works correctly for typical inputs, Jest Guru can generate a test case where the function is given positive integers and returns the correct sum.

Example

A function that divides two numbers.

Scenario

If a developer wants to test how their 'divide' function handles division by zero, Jest Guru will generate the appropriate test cases to check for errors or unexpected behavior.

Example

A function that fetches data from an API.

Scenario

When testing asynchronous code, such as API calls, Jest Guru can produce test cases using 'async/await' or Jest's 'done' callback to handle promises and ensure the function behaves as expected under various conditions.

Example

A function that relies on an external API.

Scenario

To isolate the unit under test, Jest Guru can generate test cases that mock external dependencies, allowing developers to focus on the function's logic without making actual network calls.

Example

A function that calculates discounts based on customer type.

Scenario

Jest Guru can create parameterized tests to cover multiple input scenarios in a single test, such as applying different discounts for various customer types and ensuring the function returns the correct output for each case.
