关于 testunit-skill

为使用 Test::Unit 编写和运行 Ruby 测试提供参考，面向 Ruby 开发者，涵盖测试结构、断言、测试夹具和测试发现。

主要功能

  1. 01Test::Unit 测试类模式
  2. 02常用断言方法
  3. 03类级启动与关闭夹具
  4. 04测试命名与顺序指南
  5. 05运行和自动发现命令

适用场景

  1. 01为 Ruby 类编写测试
  2. 02在测试类中共享初始化流程
  3. 03运行测试文件或发现测试

安装

复制下面的命令，在终端中运行。

$npx skills add https://github.com/lambdatest/agent-skills --skill testunit-skill

安装后在 Claude Code 中输入/testunit-skill确认已加载。

附带文件reference/advanced-patterns.mdreference/playbook.md

详细介绍

Test::Unit Ruby 技能

核心模式

基本测试
require 'test/unit'

class TestCalculator < Test::Unit::TestCase
  def setup
    @calc = Calculator.new
  end

  def test_addition
    assert_equal(5, @calc.add(2, 3), "2 + 3 should equal 5")
  end

  def test_subtraction
    assert_equal(1, @calc.subtract(3, 2))
  end

  def test_division_by_zero
    assert_raise(ZeroDivisionError) { @calc.divide(10, 0) }
  end

  def test_float_division
    assert_in_delta(3.33, @calc.divide(10, 3), 0.01)
  end

  def teardown
    # cleanup
  end
end
断言
assert_equal(expected, actual, message = nil)
assert_not_equal(unexpected, actual)
assert_true(value)
assert_false(value)
assert_nil(value)
assert_not_nil(value)
assert_instance_of(klass, obj)
assert_kind_of(klass, obj)
assert_respond_to(obj, :method_name)
assert_match(/pattern/, string)
assert_no_match(/pattern/, string)
assert_include(collection, item)
assert_not_include(collection, item)
assert_empty(collection)
assert_not_empty(collection)
assert_raise(ErrorClass) { block }
assert_nothing_raised { block }
assert_in_delta(expected, actual, delta)
assert_operator(value, :>, 5)
assert_send([obj, :method, arg])
assert_block("message") { condition }
测试夹具
class TestDatabase < Test::Unit::TestCase
  def self.startup
    # Once before all tests in class
    @@db = Database.connect('test')
  end

  def self.shutdown
    # Once after all tests in class
    @@db.disconnect
  end

  def setup
    # Before each test
    @@db.begin_transaction
  end

  def teardown
    # After each test
    @@db.rollback
  end
end
测试排序与命名
class TestUserService < Test::Unit::TestCase
  # Methods must start with 'test_'
  def test_create_user
    user = UserService.create('Alice', '[email protected]')
    assert_not_nil(user)
    assert_equal('Alice', user.name)
  end

  def test_find_user_by_email
    user = UserService.find_by_email('[email protected]')
    assert_instance_of(User, user)
  end
end

安装：gem install test-unit

运行：ruby test/test_calculator.rb 或 ruby -Itest -e "Dir.glob('test/**/test_*.rb').each{|f| require f}"

自动发现：testrb test/（需要 test-unit gem）
