GSL_test

testing

go的测试由go test命令和testing包组成.

测试程序命名:

XXX.go # 测试文件和源码放在一个包中
XXX_test.go

测试程序结构:

import "testing"

# 单元测试
# go test 会自动执行
func TestXXX(t *testing.T) {}

# 性能测试
# go test XXX_test.go -test.bench=".*"  压力测试需要指定才能执行
func BenchmarkXXX(b *testing.B) {}

constants

variables

functions

T

管理测试状态并支持格式化测试的日志.

struct:

type T struct {}

methods:

// 将当前测试标识为失败,但继续执行该文件剩下的测试
func (c *T) Fail()

// 将当前测试标识为失败,并停止执行该测试, 继续执行下一个测试文件.
func (c *T) FailNow()

// 用于报告测试函数是否失败
func (c *T) Failed() bool

func (c *T) Log(args ...interface{})
func (c *T) Logf(format string, args ...interface{})

# 相当于Log/Logf之后调用Fail.(当前case失败)
func (c *T) Error(args ...interface{})
func (c *T) Errorf(format string, args ...interface{})

# 相当于Log/Logf之后调用FailNow.(当前测试文件失败)
func (c *T) Fatal(args ...interface{})
func (c *T) Fatalf(format string, args ...interface{})

func (c *T) Skip(args ...interface{})
func (c *T) SkipNow()
func (c *T) Skipf(format string, args ...interface{})
func (c *T) Skipped() bool

B

管理基准测试的计时行为,并指示应该迭代的运行测试多少次.

struct:

type B struct {
    N int
}

methods:

func (c *B) Fail()
func (c *B) FailNow()
func (c *B) Failed() bool

func (c *B) Error(args ...interface{})
func (c *B) Errorf(format string, args ...interface{})

func (c *B) Fatal(args ...interface{})
func (c *B) Fatalf(format string, args ...interface{})

func (c *B) Log(args ...interface{})
func (c *B) Logf(format string, args ...interface{})

func (c *B) Skip(args ...interface{})
func (c *B) SkipNow()
func (c *B) Skipf(format string, args ...interface{})
func (c *B) Skipped() bool
