   A New Testing Framework was born …

5. 5.

   Rgot Ruby + Golang Testing ksss/rgot !

6. 6.

   $ gem i rgot ksss/rgot ! ruby 2.0 ʙ

7. 7.

   !? ksss/rgot !

8. 8.

   Again? ksss/rgot !

9. 9.

   Do We Have to Learning New Things? ksss/rgot !

10. 10.

    Rgot is Translation from Golang Testing to Ruby ksss/rgot !

11. 11.

    Incidentally You Can Learn Golang Testing! ksss/rgot !

12. 12.

    Golang ksss/rgot ! package foo_test func TestFooBar(t *testing.T) { if

    3 != (1 + 2) { t.Error("failed") } }
13. 13.

    Rgot ksss/rgot ! module FooTest def test_foo(t) if 3 !=

    (1 + 2) t.error("failed") end end end
14. 14.

    Golang-ish ksss/rgot !

15. 15.

    Golang ksss/rgot ! $ go test -v === RUN TestFoo

    --- PASS: TestFoo (1.01s) === RUN TestBar --- PASS: TestBar (1.00s) === RUN TestBaz --- PASS: TestBaz (1.01s) PASS ok ksss/gotest 3.017s
16. 16.

    Rgot ksss/rgot ! $ rgot -v === RUN test_foo ---

    PASS: test_foo (1.01s) === RUN test_bar --- PASS: test_bar (1.00s) === RUN test_baz --- PASS: test_baz (1.01s) PASS ok RgotTest 3.042s
17. 17.

    Golang ksss/rgot ! package foo_test func BenchmarkQux(b *testing.B) { for

    i := 0; i < b.N; i++ { foo.Qux() } }
18. 18.

    Rgot ksss/rgot ! module FooTest def benchmark_qux(b) i = 0

    while i < b.n Foo.qux i += 1 end end end
19. 19.

    Golang ksss/rgot ! package pow_test func BenchmarkPow(b *testing.B) { b.RunParallel(func(pb

    *testing.PB) { for pb.Next() { math.Pow(1000.0, 1000.0) } }) }
20. 20.

    Rgot ksss/rgot ! module PowTest def benchmark_pow(b) b.run_parallel do |pb|

    while pb.next 1000.0 ** 1000.0 end end end end
21. 21.

    Golang ksss/rgot ! $ go test -bench . -cpu 2,4

    Golang ksss/rgot ! package foo_test func ExampleFoo { fmt.Println(foo.Say()) //

    Output: // foo }
24. 24.

    Rgot ksss/rgot ! module FooTest def example_foo puts Foo.say #

    Output: # foo end end
25. 25.

    Golang ksss/rgot ! $ go test -v === RUN ExampleFoo

    --- FAIL: ExampleFoo (0.00s) got: bar want: foo FAIL exit status 1 FAILgithub.com/ksss/gotest 0.005s

    Thinking ksss/rgot !

    Diversity ksss/rgot !

29. 29.

    Testing before Benchmark ksss/rgot !

30. 30.

    Testable Sample Code ksss/rgot !

31. 31.

    Not Need /test or /spec Dir ksss/rgot !

    Short Class Name testing.M => Rgot::M testing.T => Rgot::T testing.B

    => Rgot::B ksss/rgot !
34. 34.

    Zero Assert ksss/rgot !

35. 35.

    t.error() ksss/rgot !

36. 36.

    More Thinking ksss/rgot !

37. 37.

    Assert Oriented v.s. Error log Oriented ksss/rgot !

38. 38.

    Assert Oriented case ksss/rgot ! mimitest, test-unit, rspec, etc…

39. 39.

    case ksss/rgot ! Error log Oriented

40. 40.

    Error Report is Important ksss/rgot !

41. 41.

    Precise errors are particularly important when the programmer seeing the

    errors is not familiar with the code. #https://golang.org/doc/faq#assertions ksss/rgot !
42. 42.

    Words ksss/rgot !

43. 43.

    Words - assert - should - expect - must minitest,

    test-unit, rspec, … ksss/rgot !
44. 44.

    Words - want - got - failed - invalid Golang

    testing package ksss/rgot !
45. 45.

    Words (hypothesis) minitest, test_unit, rspec,… Golang testing package Hard Soft
