Note for image comparison based on JS lang

Note for me. Image/Visual comparison tools. Just for comparison. I like kobold, blink-diff, than reg-suit since kobold can manage comparison area. But reg-suit can add features easy with plugins. — KazuCocoa (@Kazu_cocoa) March 6, 2018 The reg-suit is https://github.com/reg-viz/reg-suit . https://github.com/KazuCocoa/ex-reg-suit The kobold is https://github.com/yahoo/kobold .

Read “Mastering Blockchain”

[Flutter]Flutter app with Appium

I touch [Flutter]some thoughts for the Flutter (v0.1.0) before. And this time, I tried to run the app with Appium. We can run UI test with Appium as well as native apps. But Flutter apps have no accessibility identifier and customised resource id. So, it’s quite difficult to implement robust test automation scenario so far.…More

Taste mabl which provides ML-driven test automation service

Lately, ML related technologies step into industry section and many engineers challenge to integrate them into their services. The movement also comes into test/quality industry. I also have some ideas to use them though. A few weeks ago, I found a service which named mabl which provides ML-driven test automation service. The service run tests…More

[Elixir]property based testing with stream_data

Elixir will bundle property-based testing in the core. http://elixir-lang.github.io/blog/2017/10/31/stream-data-property-based-testing-and-data-generation-for-elixir/ We can see the prototype for the library from https://github.com/whatyouhide/stream_data . The following lines are the example I applied the library before. https://github.com/KazuCocoa/http_proxy/pull/47/commits/11bf6ff5a763c97c3ec6c7bc4a1811de53a6d0c2 We can see more details from https://hexdocs.pm/stream_data/StreamData.html and you can see how flexible the methods. link [Erlang][Software Test]Property-based testing/QuickCheck Testing https://www.cs.tufts.edu/~nr/cs257/archive/john-hughes/quick.pdfMore

Touch Spinnaker

https://www.spinnaker.io I’ve tried to conduct the Spinnaker to understand the behaviour and its architecture. Walk through the setup tutorial, https://www.spinnaker.io/setup/ , and read architectural things. I could image what is relevant and what kind of tools are integrated in the Spinnaker. https://www.spinnaker.io/reference/architecture/#spinnaker-microservices As persistent storage, I see https://www.spinnaker.io/setup/install/storage/minio/ as the S3 clone. I didn’t know…More

“ジョブ理論”を読んだ。原書タイトルの方がしっくりくる内容だった。

ジョブ理論を読んだ。確か、昨年の間に買っていたのだが、Kindleの整理で見つけたという感じ… 中身に関しては、問題発見自体の難しさ、捉えにくさに対して「ジョブ」という表現を持ち込んだ、という感じのもの。それを様々な実例から実証している。大学時代に学んだ教授のもとで耳にタコができるくらい？よく言われたことを想起した。つまるところ、一番難しい、問題を発見し、定義する。それを行う1つの手法という感じですね。 “理論”といっているのでどれだけ確立されたものかと見てみると、実証的なものが多く、”jobs theory”と強くいうにはまだのよう（ここは著者も言及してはしますね）。原書のタイトルを見てみると Competing Against Luck: The Story of Innovation and Customer Choice とあるので、個人的にはこちらの方がスッと中身も、読んだ後も馴染む感じがしますね。 視点を利用ユーザ、顧客に合わせ、彼ら/彼女らが何か進むために “何か” を雇用する。そういう考え方で物事を捉え、実装に落とし込んでいくという流れ。 A person hire a job to evolve themselves with it. The job is hired by the person to proceed the evolution. The job includes particular situations. The job isn't needs though. — KazuCocoa (@Kazu_cocoa) February 17, 2018…More
