gotests 
gotests makes writing Go tests easy. It's a Golang commandline tool that generates table driven tests based on its target source files' function and method signatures. Any new dependencies in the test files are automatically imported.
Demo
The following shows gotests in action using the official Sublime Text 3 plugin. Plugins also exist for Emacs, also Emacs, Vim, Atom Editor, Visual Studio Code, and IntelliJ Goland.
Installation
Minimum Go version: Go 1.6
Use go get to install and update:
$ go get -u github.com/cweill/gotests/...Usage
From the commandline, gotests can generate Go tests for specific source files or an entire directory. By default, it prints its output to stdout.
$ gotests [options] PATH ...Available options:
-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 stdinContributions
