Installation

go get github.com/zhulongcheng/testsql

Usage

Create a folder for the table-schema file and sql files:

testsql
├── fixtures
│   └── users.sql
└── schema.sql

The table-schema file include all tables schema, it would be like this:

CREATE TABLE `users` (
    `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
    `name` varchar(32) CHARACTER SET utf8mb4 NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

The sql file would be like this:

INSERT INTO `users` (`id`, `name`)
VALUES
    (1, 'foo');

Your tests would be like this:

var TS *testsql.TestSQL

func newTS() *testsql.TestSQL {
    dsn := "user:password@tcp(host:port)/test_db_name"
    tableSchemaPath := "testsql/schema.sql"
    dirPath := "testsql/fixtures"
    ts := testsql.New(dsn, tableSchemaPath, dirPath)
    return ts
}

func initTestDB() {
    TS = newTS()
    
    // set sql-driver/orm to read/write data from TS's DSN
    // Driver = sql.Open(TS.Config.DSN)
    // ORM = ORM.New(TS.Config.DSN)
}

func TestMain(m *testing.M) {
    initTestDB()
    r := m.Run()
    TS.DropTestDB()
    os.Exit(r)
}

func TestUser(t *testing.T) {
    TS.Use("users.sql")
    defer TS.Clear()
    
    // user := GetUserByID(1)
    // if user.name != "foo" {
    //    t.Errorf("not equal, expected: %s, actual: %s", "foo", user.name) 
    // }
}

API Reference

TestSQL.Exec generates test data from sql string.

TestSQL.Use generates test data from sql files.

TestSQL.Clear deletes data of all tables

TestSQL.DropTestDB drops the database created by TestSQL.

FQA

Set sql-driver/orm to read/write data from TestSQL's DSN

    db := yourSQLDriver.Open(TS.Config.DSN)
    // or db := yourORM.Open(TS.Config.DSN)

    yourModel.SetDB(db)  // reset db
