feat: request match by body (#12)

[diego-aquino]

Features

• [#zimic] Added support to restrict request trackers by body.

const creationTracker = authInterceptor
  .post('/users')
  .with({
    body: creationPayload,
  })
  .respond((request) => {
    const user: User = {
      id: crypto.randomUUID(),
      name: request.body.name,
      email: request.body.email,
    };

    return {
      status: 201,
      body: user,
    };
  });

const response = await createUser(creationPayload);
expect(response.status).toBe(201);

Refactoring

• [#zimic] Simplified request and response body schemas.
  • Unified HttpInterceptorSchema.RequestBody and HttpInterceptorSchema.ResponseBody into HttpInterceptorSchema.Body, as the previous RequestBody and ResponseBody had the same semantics.
• [#zimic] Improved HTTP interceptor test scenarios, following real-world cases more closely for each method.
  Closes HTTP interceptor request match by body #12.
