HttpPostとServletFileUploadでContentTypeを取得できない
//POSTを投げる側のコード
HttpClient httpClient = HttpClientBuilder.create().build();
HttpPost httpPost = new HttpPost("http://127.0.0.1:8080/test/post");
MultipartEntityBuilder params = MultipartEntityBuilder.create();
params.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
//ContentTypeをセットしないと文字化けします
params.addTextBody("text", "マルチバイトテキスト", ContentType.create("text/plain", MIME.UTF8_CHARSET));

Promise Queue

非同期処理を含むイベントが連続で発火されて、それを、同期に実行したい（発火された順番で必ず前の処理が終わってから実行したい）時に使えるテクニック。めちゃめちゃに実行される非同期処理を一列に整列させるイメージです。

var promises = [];
promises.push(Promise.resolve());

promises.push(
  promises.shift().then(() => {
    return new Promise(resolve => {
 setTimeout(() => {

A function in a plane object is the named function in nodejs (v6.10.2).
const obj = {
foobar: function(){}
}
obj.foobar.toString() == (function(){}).toString() //false
obj.foobar.toString() == (function foobar(){}).toString() //true
obj.foobar.toString() //function foobar() {}

How to check checkboxes by values using javascript selenium.

Both getAttribute and isSelected are asynchronous methods, so my solution has become such complicated. Does anyone know a simpler solution?
