How Bevel Works

1

Deep Dependency Analysis

Bevel automatically identifies all dependencies, both direct and indirect, within your target function.

2

Intelligent Mocking Strategy

Configure each dependency with smart defaults: use the real implementation, create a mock, or generate a fake object.

3

Prompt Engineering & Test Generation

Use our built-in AI or copy the perfectly structured prompt to your preferred agent (Copilot, Cursor, etc.).

Why Dependency Extraction is important for unit testing

Speed: Tests in Minutes, Not Hours

Drastically reduce the time and effort required to write unit tests, especially for complex functions with many dependencies.

Accuracy: Context-Rich Generation

By providing detailed context to the AI, Bevel significantly increases the quality of generated tests with proper mocks and assertions.

Complete Control: Configure Your Way

Fine-grained control over dependencies with smart defaults - decide exactly what to mock, fake, or use directly.

Complexity Handling: Even for Legacy Code

Successfully generate tests for complex code with tangled dependencies that would be nearly impossible to test manually.
