无法让测试适用于 INSERT 语句

小伙伴们对Golang编程感兴趣吗？是否正在学习相关知识点？如果是，那么本文《无法让测试适用于 INSERT 语句》，就很适合你，本篇文章讲解的知识点主要包括。在之后的文章中也会多多分享相关知识点，希望对大家的知识积累有所帮助！

我们花了两周令人沮丧的时间尝试使用 sqlmock 的函数和方法的每一种可能的排列，但无法对 insert 语句进行测试。这是非常基本的妈妈和流行 sql。只是使用 gorm 进行简单的插入。

要发布的代码太多，而且这里列出了许多错误和方法的排列，但我将发布最新的。

type anytime struct{}

func (a anytime) match(v driver.value) bool {
    _, ok := v.(time.time)
    return ok
}

func testinsertstoragepool(t *testing.t) {

    cases := []struct {
        givenpool    storagepool
        wantederror  error
    }{
        {
            givenpool: storagepool{
                name:   "pool1",
                poolid: "1",
                type:   "networkfilesystem",
                volumes: []volume{
                    {
                        name:      "vol01",
                        storageid: "1",
                        type:      "root",
                        volumeid:  "1",
                    },
                },
            },
            wantederror: nil,
        },
    }

    for _, c := range cases {

        db, mock, err := sqlmock.new()
        if err != nil {
            t.fatal(err)
        }

        // every attempt we make we try "postgres", "mysql" and "sqlite3" here
        db, err := gorm.open("sqlite3", db)
        if err != nil {
            t.fatal(err)
        }
        db.logmode(true)

        mock.expectbegin()
        mock.expectexec(`insert into "storage_pools"`).withargs(
            anytime{},
            anytime{},
            nil,
            0,
            0,
            "",
            "",
            "",
            0,
            0,
            0,
            "",
            c.givenpool.name,
            "",
            0,
            "",
            "",
            c.givenpool.poolid,
            "",
            "",
            "",
            c.givenpool.type,
            "",
            "").willreturnresult(sqlmock.newresult(1, 1))

        mock.expectcommit()

        err = insertstoragepool(db, &c.givenpool)
        if err != nil {
            fmt.fprintf(os.stderr, "error: %s\n", err)
        }

        if !reflect.deepequal(err, c.wantederror) {
            t.errorf("expecting errror %q, got %q", c.wantederror, err)
        }

    }

}

此尝试的错误：

解决方案

错误消息告诉您在您期望的插入之后正在执行附加插入：

在您的代码中，我们可以看到您的 StoragePool 结构在切片中也有一些 volumes 。

因此，当您调用 InsertStoragePool 时，可能首先将一行插入到 storage_pools 中，然后插入 volumes 。

在添加提交的期望之前，您应该为该插入添加新的期望。
