大家好,今天本人给大家带来文章《进行电子邮件的测试和更改操作》,文中内容主要涉及到,如果你对Golang方面的知识点感兴趣,那就请各位朋友继续看下去吧~希望能真正帮到你们,谢谢!

问题内容

我正在尝试运行 go 测试,这部分失败了。我正在使用 changeemail 函数进行测试。我真的不知道发生了什么。

func testchangeemail(t *testing.t) {
    ctx := context.background()
    inittestcontext(ctx)

    buf := bytes.buffer{}
    enc := json.newencoder(&buf)
    enc.encode(testprofile)
    // create the request object with jwt
    req, err := http.newrequestwithcontext(ctx, "put", "http://localhost:8080/v1/profile/", &buf)
    if err != nil {
        t.fatal(err)
    }

    //  // 1) create the initial profile

    const sqlselectall = `select * from "profiles" where email = $1 order by "profiles"."id" limit 1`
    const sqlcreate = `insert into "profiles" ("created_at","updated_at","deleted_at","display_name","email","email_verified","id") values ($1,$2,$3,$4,$5,$6,$7) returning "id"`
    expected := sqlmock.newrows([]string{"id", "display_name", "email"}).addrow(testprofile.id, testprofile.displayname, testprofile.email)
    mock.expectquery(regexp.quotemeta(sqlselectall)).withargs(testprofile.email).willreturnerror(fmt.errorf("not found"))
    mock.expectbegin()
    mock.expectquery(regexp.quotemeta(sqlcreate)).withargs(anytime{}, anytime{}, nil, testprofile.displayname, testprofile.email, testprofile.emailverified, sqlmock.anyarg()).willreturnrows(expected)
    mock.expectcommit()

    newemail := "[email protected]"
    //  // 2) change the initial profile's email
    const sqlupdate = `update "profiles" set "email"=$1 where "email"=$2`
    mock.expectbegin()
    mock.expectexec(regexp.quotemeta(sqlupdate)).withargs(newemail, testprofile.email).willreturnresult(sqlmock.newresult(0, 1))
    mock.expectcommit()

    if err := executeandvalidaterequest(req, http.statuscreated); err != nil {
        t.error(err)
    }
}

我收到的错误是 --- fail: testchangeemail (0.00s) 恐慌:运行时错误:无效的内存地址或 nil 指针取消引用 [已恢复] 恐慌:运行时错误:无效的内存地址或 nil 指针取消引用 [信号 sigsegv : 分段违规代码=0x2 addr=0x18 pc=0x102d2fc94]

这是 legec 指出的下面的堆栈跟踪。我只是想添加所有我能添加的信息

正确答案


除了此错误消息之外,您还有一个堆栈跟踪,指示代码失败的位置。

从上到下读取堆栈跟踪:

  • 在恐慌之后有几帧,因为一些代码和函数被执行来处理恐慌本身,
  • 然后你就会看到恐慌本身:
    panic({0x1050f65e0, 0x105512000})
        /usr/local/go/src/runtime/panic.go:884 +0x204
    此代码位于标准库中
  • 后面的行会告诉您哪一行触发了恐慌:
    gitlab/developers/server/profile.changeEmail({0x105199db8, 0x14000341e80}, 0x14000374600)
        /Users/example/Documents/project/server/profile/handlers.go:75 +0x44
    该行触发了零指针取消引用:server/profile/handlers.go:75
  • 您还拥有导致执行该行的函数调用序列
    例如:在堆栈的底部,您可以看到,在测试函数 testchangeemail() 中,触发错误的调用位于 handlers_test.go:282,其顶部的框架表明它是对executeandvalidaterequest()

您现在可以调试代码,看看它是否是项目中的错误,或者是测试中未初始化的内容。
