Implement Lifecycle Hooks

[hendriknielaender]

Description

This feature would provide users with greater control over their benchmarking process.

Proposed Hooks

• beforeAll: A hook that runs once before all tests begin. This can be used for initial setup procedures.
• afterAll: A hook that runs once after all tests have completed. This is ideal for cleanup operations.
• beforeEach: A hook that runs before each individual test. Useful for setting up test-specific conditions.
• afterEach: A hook that runs after each individual test. Helps in resetting conditions or cleaning up after each test.

Use Case

These hooks would be particularly beneficial for complex benchmarks that require specific setup and teardown operations before and after running tests. They provide flexibility and control, ensuring that each test runs under the right conditions and that resources are properly managed.

Implementation

Ideally, these hooks should be easy to use and integrate into existing tests with minimal configuration. Here's a rough idea of what the interface might look like:

const LifecycleHooks = struct {
    beforeAll: fn () void,
    afterAll: fn () void,
    beforeEach: fn () void,
    afterEach: fn () void,
};

pub const Config = struct {
    ...
    hooks: LifecycleHooks = .{},
    ...
};
