The MiniTest Assertions Cheat Sheet was released by CITguy on Cheatography. Here's how they described it: Download the PDF version here View Entire Discussion (1 Comments). Require 'minitest/autorun' # 注意有些资料中，测试类不是继承自MiniTest::Test， # 那是MiniTest 5之前的做法，MiniTest会通知你改正 class TestMyLife MiniTest:: Test # 这个方法会在各个测试之前被调用 def setup @me = People.

Minitest Cheat Sheet Excel

Ruby’s standard testing suite, MiniTest, is in dire need of a quick-and-handy reference for its syntax. I’ve put one together comparing the unit syntax (assert/refute) and the spec syntax (must/wont). You can see it below or download the Google Spreadsheet I made and roll your own sheet (HTML, XLS)

Test syntax

Unit	Spec	Arguments	Examples
assert_empty refute_empty	must_be_empty wont_be_empty	obj, msg=nil	assert_empty [] refute_empty [1,2,3] [].must_be_empty [1,2,3].wont_be_empty
assert_equal refute_equal	must_equal wont_equal	exp, act, msg=nil	assert_equal 2, 2 refute_equal 2,1 2.must_equal 2 2.wont_equal 1
assert_in_delta refute_in_delta	must_be_within_delta wont_be_within_delta	exp, act, dlt=0.001, msg=nil	assert_in_delta 2012, 2010, 2 refute_in_delta 2012, 3012, 2 2012.must_be_within_delta 2010, 2 2012.wont_be_within_delta 3012, 2
must_be_close_to wont_be_close_to	act, dlt=0.001, msg=nil	2012.must_be_close_to 2010, 2 2012.wont_be_close_to 3012, 2
assert_in_epsilon refute_in_epsilon	must_be_within_epsilon wont_be_within_epsilon	a, b, eps=0.001, msg=nil	assert_in_epsilon 1.0, 1.02, 0.05 refute_in_epsilon 1.0, 1.06, 0.05 1.0.must_be_within_epsilon 1.02, 0.05 1.0.wont_be_within_epsilon 1.06, 0.05
assert_includes refute_includes	must_include wont_include	collection, obj, msg=nil	assert_includes [1, 2], 2 refute_includes [1, 2], 3 [1, 2].must_include 2 [1, 2].wont_include 3
assert_instance_of refute_instance_of	must_be_instance_of wont_be_instance_of	klass, obj, msg=nil	assert_instance_of String, 'bar' refute_instance_of String, 100 'bar'.must_be_instance_of String 100.wont_be_instance_of String
assert_kind_of refute_kind_of	must_be_kind_of wont_be_kind_of	klass, obj, msg=nil	assert_kind_of Numeric, 100 refute_kind_of Numeric, 'bar' 100.must_be_kind_of Numeric 'bar'.wont_be_kind_of Numeric
assert_match refute_match	must_match wont_match	exp, act, msg=nil	assert_match /d/, '42' refute_match /d/, 'foo' '42'.must_match /d/ 'foo'.wont_match /d/
assert_nil refute_nil	must_be_nil wont_be_nil	obj, msg=nil	assert_nil [].first refute_nil [1].first [].first.must_be_nil [1].first.wont_be_nil
assert_operator refute_operator	must_be wont_be	o1, op, o2, msg=nil	assert_operator 1, :<, 2 refute_operator 1, :>, 2 1.must_be :<, 2 1.wont_be :>, 2
assert_output	must_output	stdout = nil, stderr = nil	assert_output('hin'){ puts 'hi' } Proc.new{puts 'hi'}.must_output 'hin'
assert_raises	must_raise	*exp	assert_raises(NoMethodError){ nil! } Proc.new{nil!}.must_raise NoMethodError
assert_respond_to refute_respond_to	must_respond_to wont_respond_to	obj, meth, msg=nil	assert_respond_to 'foo',:empty? refute_respond_to 100, :empty? 'foo'.must_respond_to :empty? 100.wont_respond_to :empty?
assert_same refute_same	must_be_same_as wont_be_same_as	exp, act, msg=nil	assert_same :foo, :foo refute_same ['foo'], ['foo'] :foo.must_be_same_as :foo ['foo'].wont_be_same_as ['foo']
assert_silent	must_be_silent	-	assert_silent{ 1 + 1 } Proc.new{ 1 + 1}.must_be_silent
assert_throws	must_throw	sym, msg=nil	assert_throws(:up){ throw :up} Proc.new{throw :up}.must_throw :up

Test Setup

Unit	Spec
setup()	before(type = nil, &block)
teardown()	after(type = nil, &block)

Mocks

Minitest Cheat Sheet Pdf

via MiniTest::Mock

Minitest Cheat Sheet Printable

• expect(name, retval, args=[]) – Expect that method name is called, optionally with args or a blk, and returns retval.

  Example:

• verify – Verify that all methods were called as expected. Raises MockExpectationError if the mock object was not called as expected.

Other syntax

• def flunk(msg=nil)
• def pass(msg=nil)
• def skip(msg=nil, bt=caller)
• def it (desc='anonymous', &block)
• i_suck_and_my_tests_are_order_dependent!() – Call this at the top of your tests when you absolutely positively need to have ordered tests. In doing so, you’re admitting that you suck and your tests are weak. (TestCase public class method)
• parallelize_me!() – Call this at the top of your tests when you want to run your tests in parallel. In doing so, you’re admitting that you rule and your tests are awesome.
• make_my_diffs_pretty!() – Make diffs for this TestCase use pretty_inspect so that diff in assert_equal can be more details. NOTE: this is much slower than the regular inspect but much more usable for complex objects.
