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 stdin
