#### 简介
Ginkgo是一个成熟的Go测试框架，旨在帮助您编写富有表现力的规范。Ginkgo建立在Go的基础之上，并由Gomega匹配器库补充。Ginkgo和Gomega一起让您清楚地表达规格背后的意图：testing

```go
import (
    . "github.com/onsi/ginkgo/v2"
    . "github.com/onsi/gomega"
    ...
)

Describe("Checking books out of the library", Label("library"), func() {
    var library *libraries.Library
    var book *books.Book
    var valjean *users.User
    BeforeEach(func() {
        library = libraries.NewClient()
        book = &books.Book{
            Title: "Les Miserables",
            Author: "Victor Hugo",
        }
        valjean = users.NewUser("Jean Valjean")
    })

When("the library has the book in question", func() {
        BeforeEach(func(ctx SpecContext) {
            Expect(library.Store(ctx, book)).To(Succeed())
        })

Context("and the book is available", func() {
            It("lends it to the reader", func(ctx SpecContext) {

                Expect(valjean.Books()).To(ContainElement(book))
                Expect(library.UserWithBook(ctx, book)).To(Equal(valjean))
            }, SpecTimeout(time.Second * 5))

It("tells the user", func(ctx SpecContext) {

                Expect(valjean.Holds(ctx)).To(ContainElement(book))

By("when Javert returns the book")
                Expect(javert.Return(ctx, library, book)).To(Succeed())

By("it eventually informs Valjean")
                notification := "Les Miserables is ready for pick up"
                Eventually(ctx, valjean.Notifications).Should(ContainElement(notification))

Expect(valjean.Checkout(ctx, library, "Les Miserables")).To(Succeed())
                Expect(valjean.Books(ctx)).To(ContainElement(book))
                Expect(valjean.Holds(ctx)).To(BeEmpty())
            }, SpecTimeout(time.Second * 10))
        })  
    })

When("the library does not have the book in question", func() {
        It("tells the reader the book is unavailable", func(ctx SpecContext) {
            err := valjean.Checkout(ctx, library, "Les Miserables")
            Expect(error).To(MatchError("Les Miserables is not in the library catalog"))
        }, SpecTimeout(time.Second * 5))
    })
})
