# 代码静态检查发现可能的bug或者可疑的构造
go vet .

# 竞态检测
go build -race -v .

# 开启本地官网

# 运行所有单元测试
# 在当前目录运行所有测试，并且每个测试函数都会执行一次，同时输出详细的测试信息。这对于调试和查看测试详细输出很有用。
go test -count=1 -v . 

# 运行所有单元测试，并查看测试覆盖率
go test -count=1 -v -cover .

# 运行所有单元测试，并查看测试覆盖率，竞态检测
go test -count=1 -v -cover -race .

# 并发测试正确
go test -count=1 -v -race -run=TestConcurrent_DbInsertOk . 
# 并发测试错误
go test -count=1 -v -race -run=TestConcurrent_DbSelectErr . 

单元测试 sql

# mysql
CREATE TABLE `test` (
  `id` int unsigned NOT NULL AUTO_INCREMENT,
  `nickname` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
  
# sqlite3
CREATE TABLE "test" (
  "id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
  "nickname" text NOT NULL DEFAULT ''
);
