篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了gotests自动生成测试用例相关的知识，希望对你有一定的参考价值。
发现一个自动生成测试用例的工具gotests。
gotests
https://github.com/cweill/gotests
下载
go get -u github.com/cweill/gotests/...
举个栗子：
add.go
package main
func Add(a int, b int) int
return a + b
同目录下执行
gotests -all -w ./add.go
同目录自动生成 add_test.go文件
package main
import "testing"
func TestAdd(t *testing.T)
type args struct
a int
b int
tests := []struct
name string
args args
want int
// TODO: Add test cases.
for _, tt := range tests
t.Run(tt.name, func(t *testing.T)
if got := Add(tt.args.a, tt.args.b); got != tt.want
t.Errorf("Add() = %v, want %v", got, tt.want)
)
填充用例数据：
package main
import "testing"
func TestAdd(t *testing.T)
type args struct
a int
b int
tests := []struct
name string
args args
want int
// TODO: Add test cases.
"a=3,b=1",
args3, 1,
4,
,
"a=3,b=-1",
args3, -1,
4,
,
for _, tt := range tests
t.Run(tt.name, func(t *testing.T)
if got := Add(tt.args.a, tt.args.b); got != tt.want
t.Errorf("Add() = %v, want %v", got, tt.want)
)
完成。接下来执行go test .就可以跑用例啦
其他参数说明：
$ gotests [options] PATH …
-all generate tests for all functions and methods-excl regexp. generate tests for functions and methods that don’t match. Takes precedence over -only, -exported, and -all
-exported generate tests for exported functions and methods. Takes precedence over -only and -all
-i print test inputs in error messages
-only regexp. generate tests for functions and methods that match only.Takes precedence over -all
-nosubtests disable subtest generation when >= Go 1.7
-parallel enable parallel subtest generation when >= Go 1.7.
-w write output to (test) files instead of stdout
-template_dir Path to a directory containing custom test
code templates. Takes precedence over -template. This can also be set via environment variable GOTESTS_TEMPLATE_DIR
-template Specify custom test code templates, e.g. testify. This can also be set via environment variable GOTESTS_TEMPLATE
-template_params_file read external parameters to template by json
with file
-template_params read external parameters to template by json
with stdin
