Ruby:如何使用 assert_nothing_raised？

Question

 assert_nothing_raised do
   @board.make_move(0,0,Board::HUMAN)
 end

文档说:

Passes if block does not throw anything.

Example:

 assert_nothing_thrown do
   [1, 2].uniq
 end

我的 make_move 方法:

def make_move(x, y, player)
    return false
 end

我得到错误:

test_can_make_valid_move_in_the_first_row(BoardTest):
ArgumentError: wrong number of arguments (1 for 2)

Answer 1

以下代码适用于我。它对你有用吗？

require 'test/unit'
require 'test/unit/ui/console/testrunner'

class MyTestClass < Test::Unit::TestCase
  def test_something
    assert_nothing_raised do
      p 'hi'
    end
  end
end

Test::Unit::UI::Console::TestRunner.run(MyTestClass)

我认为您正确使用了 assert_nothing_raised。尝试替换

@board.make_move(0,0,Board::HUMAN)

用更简单的东西，比如

p 'hi'

看看是否可行。还可以尝试注释掉测试中的所有其他代码。
