.propertiesの
junit.jupiter.execution.parallel.enabled=trueをコメントアウトすると挙動が変わる- コメントアウトするとテストの実行が直列になり4sかかる
- 並列化が有効な場合、スリープしていても1sで終わる
-
もともとあった並列化として、
surefire-pluginの機能forkCountがある- JUnit5で試すとどうもうまくいかなかった(Tests run:0 となる...)
- JUnit4で検証。

標準出力を補足できるようになった
- 12factor appのLogsの章にはログは標準出力とすべし、とある
- これを加味すると、テストで標準出力がテストできるのは心強い点となろう
