// Example code for workrequests API
// This script provides a basic example of how to use work requests using Go SDK.
// This script will:
//
//   * Read in user OCI config
//   * Retrieve a list of all Work Requests for the compartment
//   * Get Work Request details
//   * List errors related to a Work Request
//   * List logs related to a Work Request
//
// This script takes no arguments
//
// Usage:
// 		go test -v example/example_work_request_test.go
//
