ginkgo在windows下的安装使用

ginkgo在windows下的安装使用

ginkgo是GOLANG的一个测试框架

https://github.com/onsi/ginkgo

安装

建一个自己的文件夹，如D:\workspace\go-test-go
在计算机->环境变量中设置GOPATH
打开git bash
执行

go get github.com/onsi/ginkgo/ginkgogo get github.com/onsi/gomega

在git bash中cd到该目录

然后运行下ginkgo help，看下参数列表

用法摘要


ginko的测试代码由一些代码块组成：Describe 代码块描述了被测代码的行为，Context代码块则表示在不同环境下运用这些行为


    

  • 通常情况下，container块(Describe、Context块)内应该是个It块、BeforeEach、AfterEach或变量声明，而不应该放置断言。在container块中初始化了变量，如果其中一个It改变了它的值，后续的It取到的就是改变了的值，此时初始化变量总是应该在BeforeEach块中
    

    var _ = Describe("Node", func() {

    //  Context("Context test",func() {
    ret := node.GetNode("123")
    result := comm.GetHttp("456")
    //fmt.Print(ret);
    BeforeEach(func() {
        ret = 666
        fmt.Print(ret);
    })
    It("just test suc", func() {
        ret=200
        fmt.Print(ret);
        Expect(ret).Should(Equal(200))
        Expect(result).Should(Equal("456"))
    })

    It("just test fail", func() {
        fmt.Print(ret);
        Expect(ret).Should(Equal("123"))
        Expect(result).Should(Equal("4566"))
    })
    //  })
})
$ ginkgo

    • 

  • JustBeforeEach在所有BeforeEach块运行完之后并在It块运行之前运行

    var _ = Describe("Node", func() {

    //  Context("Context test",func() {
    ret := node.GetNode("123")
    result := comm.GetHttp("456")
    //fmt.Print(ret);
    BeforeEach(func() {
        ret = 666
        fmt.Print(ret);
    })
    JustBeforeEach(func(){
        ret=777
    })
    It("just test suc", func() {
        ret=200
        fmt.Print(ret);
        Expect(ret).Should(Equal(200))
        Expect(result).Should(Equal("456"))
    })

    It("just test fail", func() {
        fmt.Print(ret);
        Expect(ret).Should(Equal("123"))
        Expect(result).Should(Equal("4566"))
    })
    //  })

    • 

  • By用于梳理和标记复杂的流程和步骤，成功了不会显示，失败则将步骤打印出来，通过在Describe、Context、It等加上P或X来标记其为pending

    var _ = Describe("Node", func() {

//  Context("Context test",func() {
        ret :=  node.GetNode("123");
        result := comm.GetHttp("456");
        It("just test suc", func() {
            Expect(ret).Should(Equal(200));
            Expect(result).Should(Equal("456"));
        })

        PIt("just test fail", func() {
            Expect(ret).Should(Equal("123"));
            Expect(result).Should(Equal("4566"));
        })
//  })
})

    • 

  • 同步方式的使用：SynchronizedBeforeSuite()传入两个func，第一个必须返回[]byte，第二个必须接受这个[]byte，如一个func是在一个节点起一个server返回endpoint，第二个函数是所有节点client接受endpoint并进行连接，并发时clinet需要等待sever启动再进行连接

    同理SynchronizedAfterSuite()传入两个func，第一个func需要全部节点都执行完成，再执行由第一个节点执行第二个func。如在上述的基础上第一个func关闭所有的client，第二个func停止server
    

    ginko对并发异步也能很好的支持测试，在非container块(its，BeforeEach)等增加了一个可选的参数func(done Done)，ginkgo检查到done Done参数，遍用goroutine的方式运行body函数，需要通过关闭done channel或发送消息到channel来告诉ginkgo运行完成。如果超时了运行还未结束，ginkgo将把它标记为fail。运行下一个。
    • 

  • ginkgo常用命令：

--nodes=Node_total 指定并发节点数

控制
-r 遍历目录
-skipPackage skip目录

输出
--noColor 无颜色
--succinct 精简打印一行
--v 详细打印用例的文本和位置
--noisyPending 对pending的specs也给出信息
--trace 失败打印堆栈信息
--progress 将进入和运行每个部分的日志都打印出来 

随机
--seed=SEED

focus和skip
--skipMeasurements
--focus=REGEXP
--skip=REGXP

coverage
-race
-cover

失败动作
--failOnPending 有pending的specs就认为是fail
--failFast 失败就停止suite的运行

其他
-dryRun 只是遍历，非真实运行
-keepGoing 多个suite有一个失败了仍能继续
-untilItFails 一直运行知道失败
--slowSpecThreshold=TIME_IN_SECONDS 标记运行缓慢的spec
