 * AssertionBuilder.statusCode().lessThan(300)
 *
 * // JSON body assertions using JSONPath
 * AssertionBuilder.jsonBody('$.user.name').equals('John')
 * AssertionBuilder.jsonBody('$.users.length').equals(5)
 * AssertionBuilder.jsonBody('$.data[0].id').isNotNull()
 *
 * // Header assertions
 * AssertionBuilder.headers('content-type').contains('application/json')
 * AssertionBuilder.headers('x-rate-limit-remaining').greaterThan(0)
 *
 * // Text body assertions
 * AssertionBuilder.textBody().contains('Welcome to our API')
 * AssertionBuilder.textBody().notContains('error')
 *
 * // Response time assertions
 * AssertionBuilder.responseTime().lessThan(1000)
 * AssertionBuilder.responseTime().greaterThan(100)
