1. A New Testing Framework Rgot ksss RubyKaigi2015
2. ! " ksss _ksss_
4. A New Testing Framework was born …
5. Rgot Ruby + Golang Testing ksss/rgot !
6. $ gem i rgot ksss/rgot ! ruby 2.0 ʙ
7. !? ksss/rgot !
8. Again? ksss/rgot !
9. Do We Have to Learning New Things? ksss/rgot !
10. Rgot is Translation from Golang Testing to Ruby ksss/rgot !
11. Incidentally You Can Learn Golang Testing! ksss/rgot !
12. Golang ksss/rgot ! package foo_test func TestFooBar(t *testing.T) { if 3 != (1 + 2) { t.Error("failed") } }
13. Rgot ksss/rgot ! module FooTest def test_foo(t) if 3 != (1 + 2) t.error("failed") end end end
14. Golang-ish ksss/rgot !
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. 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. Golang ksss/rgot ! package foo_test func BenchmarkQux(b *testing.B) { for i := 0; i < b.N; i++ { foo.Qux() } }
18. Rgot ksss/rgot ! module FooTest def benchmark_qux(b) i = 0 while i < b.n Foo.qux i += 1 end end end
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. 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. Golang ksss/rgot ! $ go test -bench . -cpu 2,4 PASS BenchmarkPow-2 100000000 22.3 ns/op BenchmarkPow-4 100000000 12.5 ns/op ok github.com/pow_test 3.522s GOMAXPROCS
22. Rgot ksss/rgot ! $ rgot --bench . --cpu 2,4 --thread 2,4 PASS benchmark_pow-2(2) 25600000 74 ns/op benchmark_pow-2(4) 81920000 74 ns/op benchmark_pow-4(2) 81920000 39 ns/op benchmark_pow-4(4) 40960000 40 ns/op ok PowTest 13.603s process thread
23. Golang ksss/rgot ! package foo_test func ExampleFoo { fmt.Println(foo.Say()) // Output: // foo }
24. Rgot ksss/rgot ! module FooTest def example_foo puts Foo.say # Output: # foo end end
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
26. Rgot ksss/rgot ! $ rgot -v === RUN example_foo --- FAIL: example_foo (0.00s) got: bar want: foo FAIL exit status 1 FAILRgotTest 0.001s
27. Thinking ksss/rgot !
28. Diversity ksss/rgot !
29. Testing before Benchmark ksss/rgot !
30. Testable Sample Code ksss/rgot !
31. Not Need /test or /spec Dir ksss/rgot !
32. ksss/rgot !
33. Short Class Name testing.M => Rgot::M testing.T => Rgot::T testing.B => Rgot::B ksss/rgot !
34. Zero Assert ksss/rgot !
35. t.error() ksss/rgot !
36. More Thinking ksss/rgot !
37. Assert Oriented v.s. Error log Oriented ksss/rgot !
38. Assert Oriented case ksss/rgot ! mimitest, test-unit, rspec, etc…
39. case ksss/rgot ! Error log Oriented
40. Error Report is Important ksss/rgot !
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. Words ksss/rgot !
43. Words - assert - should - expect - must minitest, test-unit, rspec, … ksss/rgot !
44. Words - want - got - failed - invalid Golang testing package ksss/rgot !
45. Words (hypothesis) minitest, test_unit, rspec,… Golang testing package Hard Soft ksss/rgot !
46. ksss/rgot !
