Help us understand the problem. What are the problem?

More than 5 years have passed since last update.

mochaで各テストごとにテストデータを設定してbeforeEachで使う

微妙に違う処理をbeforeEachでまとめたいんだけど、テストごとにデータ設定してもどうやって参照すればいいの・・・
なときに使えるスニペット。
テストのオブジェクトにプロパティ追加してるのが少し気になるけど、現状これ以上にスマートなやり方を思いつけない。

test.js
var message;

function setMessage(str) {
  message = "Hello " + str + "!";
}

describe('メッセージのセット', function() {
  beforeEach(function() {
    setMessage(this.currentTest.testData);
  });

  it('hoge', function() {
    expect(message).to.equal('Hello hoge!');
  }).testData = 'hoge';

  it('fuga', function() {
    expect(message).to.equal('Hello fuga!');
  }).testData = 'fuga';
});
