Overview

::Minitest Assertions. All assertion methods accept a msg which is printed if the assertion fails.

Protocol: Nearly everything here boils up to #assert, which expects to be able to increment an instance accessor named assertions. This is not provided by Assertions and must be provided by the thing including Assertions. See Runnable for an example.

Instance Method Details



  

    #_synchronize  
  

  

    This method is for internal use only.

# File 'lib/minitest/assertions.rb', line 144



def _synchronize # :nodoc:
  yield
end


  








  

    #assert(test, msg = nil)  
  



  

    

Fails unless test is truthy.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 134



def assert test, msg = nil
  self.assertions += 1
  unless test then
    msg ||= "Expected #{mu_pp test} to be truthy."
    msg = msg.call if Proc === msg
    raise Minitest::Assertion, msg
  end

end


  








  

    #assert_empty(obj, msg = nil)  
  



  

    

Fails unless obj is empty.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 151



def assert_empty obj, msg = nil
  msg = message(msg) { "Expected #{mu_pp(obj)} to be empty" }
  assert_respond_to obj, :empty?
  assert obj.empty?, msg
end


  








  

    #assert_equal(exp, act, msg = nil)  
  



  

    

Fails unless exp == act printing the difference between the two, if possible.



If there is no visible difference but the assertion fails, you should suspect that your #== is buggy, or your inspect output is missing crucial details.  For nicer structural diffing, set Test.make_my_diffs_pretty!



For floats use assert_in_delta.

    #assert_in_delta(exp, act, delta = 0.001, msg = nil)  
  



  

    

For comparing Floats.  Fails unless exp and act are within delta of each other.



assert_in_delta Math::PI, (22.0 / 7.0), 0.01


  



  [ GitHub ]

    #assert_mock(mock)  
  



  

    

Assert that the mock verifies correctly.


  



  [ GitHub ]

  assert obj.nil?, msg
end


  








  

    #assert_operator(o1, op, o2 = UNDEFINED, msg = nil)  
  



  

    

For testing with binary operators. Eg:



assert_operator 5, :<=, 4


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 267



def assert_operator o1, op, o2 = UNDEFINED, msg = nil
  return assert_predicate o1, op, msg if UNDEFINED == o2

  assert o1.__send__(op, o2), msg
end


  








  

    #assert_output(stdout = nil, stderr = nil)  
  



  

    

Fails if stdout or stderr do not output the expected results. Pass in nil if you don't care about that streams output. Pass in “” if you require it to be silent. Pass in a regexp if you want to pattern match.



assert_output(/hey/) { method_with_output }



NOTE: this uses #capture_io, not #capture_subprocess_io.



See also: #assert_silent


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 285



def assert_output stdout = nil, stderr = nil
  out, err = capture_io do
    yield
  end

  err_msg = Regexp === stderr ? :assert_match : :assert_equal if stderr
  out_msg = Regexp === stdout ? :assert_match : :assert_equal if stdout

  y = send err_msg, stderr, err, "In stderr" if err_msg
  x = send out_msg, stdout, out, "In stdout" if out_msg

  (!stdout || x) && (!stderr || y)
end


  








  

    #assert_predicate(o1, op, msg = nil)  
  



  

    

For testing with predicates. Eg:



assert_predicate str, :empty?



This is really meant for specs and is front-ended by assert_operator:



str.must_be :empty?


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 308



def assert_predicate o1, op, msg = nil
  msg = message(msg) { "Expected #{mu_pp(o1)} to be #{op}" }
  assert o1.__send__(op), msg
end


  








  

    #assert_raises(*exp)  
  



  

    

Fails unless the block raises one of exp. Returns the exception matched so you can check the message, attributes, etc.



exp takes an optional message on the end to help explain failures and defaults to StandardError if no exception class is passed.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 321



def assert_raises *exp
  msg = "#{exp.pop}.\n" if String === exp.last
  exp << StandardError if exp.empty?

  begin
    yield
  rescue *exp => e
    pass # count assertion
    return e
  rescue Minitest::Skip, Minitest::Assertion
    # don't count assertion
    raise
  rescue SignalException, SystemExit
    raise
  rescue Exception => e
    flunk proc {
      exception_details(e, "#{msg}#{mu_pp(exp)} exception expected, not")
    }
  end

  exp = exp.first if exp.size == 1

  flunk "#{msg}#{mu_pp(exp)} expected but nothing was raised."
end


  








  

    #assert_respond_to(obj, meth, msg = nil)  
  



  

    

Fails unless obj responds to meth.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 349



def assert_respond_to obj, meth, msg = nil
  msg = message(msg) {
    "Expected #{mu_pp(obj)} (#{obj.class}) to respond to ##{meth}"
  }
  assert obj.respond_to?(meth), msg
end


  








  

    #assert_same(exp, act, msg = nil)  
  



  

    

Fails unless exp and act are #equal?


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 359



def assert_same exp, act, msg = nil
  msg = message(msg) {
    data = [mu_pp(act), act.object_id, mu_pp(exp), exp.object_id]
    "Expected %s (oid=%d) to be the same as %s (oid=%d)" % data
  }
  assert exp.equal?(act), msg
end


  








  

    #assert_send(send_ary, m = nil)  
  



  

    

send_ary is a receiver, message and arguments.



Fails unless the call returns a true value


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 372



def assert_send send_ary, m = nil
  where = Minitest.filter_backtrace(caller).first
  where = where.split(/:in /, 2).first # clean up noise
  warn "DEPRECATED: assert_send. From #{where}"

  recv, msg, *args = send_ary
  m = message(m) {
    "Expected #{mu_pp(recv)}.#{msg}(*#{mu_pp(args)}) to return true" }
  assert recv.__send__(msg, *args), m
end


  








  

    #assert_silent  
  



  

    

Fails if the block outputs anything to stderr or stdout.



See also: #assert_output


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 388



def assert_silent
  assert_output "", "" do
    yield
  end
end


  








  

    #assert_throws(sym, msg = nil)  
  



  

    

Fails unless the block throws sym


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 397



def assert_throws sym, msg = nil
  default = "Expected #{mu_pp(sym)} to have been thrown"
  caught = true
  catch(sym) do
    begin
      yield
    rescue ThreadError => e       # wtf?!? 1.8 + threads == suck
      default += ", not \:#{e.message[/uncaught throw \`(\w+?)\'/, 1]}"
    rescue ArgumentError => e     # 1.9 exception
      raise e unless e.message.include?("uncaught throw")
      default += ", not #{e.message.split(/ /).last}"
    rescue NameError => e         # 1.8 exception
      raise e unless e.name == sym
      default += ", not #{e.name.inspect}"
    end
    caught = false
  end

  assert caught, message(msg) { default }
end


  








  

    #capture_io  
  



  

    

Captures $stdout and $stderr into strings:



out, err = capture_io do
  puts "Some info"
  warn "You did a bad thing"
end

assert_match %r%info%, out
assert_match %r%bad%, err



NOTE: For efficiency, this method uses StringIO and does not capture IO for subprocesses. Use #capture_subprocess_io for that.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 433



def capture_io
  _synchronize do
    begin
      captured_stdout, captured_stderr = StringIO.new, StringIO.new

      orig_stdout, orig_stderr = $stdout, $stderr
      $stdout, $stderr         = captured_stdout, captured_stderr

      yield

      return captured_stdout.string, captured_stderr.string
    ensure
      $stdout = orig_stdout
      $stderr = orig_stderr
    end
  end
end


  








  

    #capture_subprocess_io  
  



  

    

Captures $stdout and $stderr into strings, using Tempfile to ensure that subprocess IO is captured as well.



out, err = capture_subprocess_io do
  system "echo Some info"
  system "echo You did a bad thing 1>&2"
end

assert_match %r%info%, out
assert_match %r%bad%, err



NOTE: This method is approximately 10x slower than #capture_io so only use it when you need to test the output of a subprocess.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 466



def capture_subprocess_io
  _synchronize do
    begin
      require "tempfile"

      captured_stdout, captured_stderr = Tempfile.new("out"), Tempfile.new("err")

      orig_stdout, orig_stderr = $stdout.dup, $stderr.dup
      $stdout.reopen captured_stdout
      $stderr.reopen captured_stderr

      yield

      $stdout.rewind
      $stderr.rewind

      return captured_stdout.read, captured_stderr.read
    ensure
      captured_stdout.unlink
      captured_stderr.unlink
      $stdout.reopen orig_stdout
      $stderr.reopen orig_stderr
    end
  end
end


  








  

    #diff(exp, act)  
  



  

    

Returns a diff between exp and act. If there is no known diff command or if it doesn't make sense to diff the output (single line, short output), then it simply returns a basic comparison between the two.

def flunk msg = nil
  msg ||= "Epic Fail!"
  assert false, msg

    #message(msg = nil, ending = nil, &default)  
  



  

    

Returns a proc that will output msg along with the default message.

    "#{custom_message}#{default.call}#{ending || "."}"
  }
end


  








  

    #mu_pp(obj)  
  



  

    

This returns a human-readable version of obj. By default #inspect is called. You can override this to use #pretty_print if you want.


  



  [ GitHub ]


  

  


# File 'lib/minitest/assertions.rb', line 107



def mu_pp obj
  s = obj.inspect

  if defined? Encoding then
    s = s.encode Encoding.default_external

    if String === obj && obj.encoding != Encoding.default_external then
      s = "# encoding: #{obj.encoding}\n#{s}"
    end
  end

  s
end


  








  

    #mu_pp_for_diff(obj)  
  



  

    

This returns a diff-able human-readable version of obj. This differs from the regular mu_pp because it expands escaped newlines and makes hex-values generic (like object_ids). This uses mu_pp to do the first pass and then cleans it up.
