### Windows support improved

- [Performance dashboards](http://perf-dash.k8s.io/#/?jobname=soak-tests-capz-windows-2019) added support for Windows
- [Unit tests](https://github.com/kubernetes/kubernetes/issues/51540) added support for Windows
- [Conformance tests](https://github.com/kubernetes/kubernetes/pull/108592) added support for Windows

- Service session affinity timeout tests are no longer required for Kubernetes network plugin conformance due to variations in existing implementations. New conformance tests will be developed to better express conformance in future releases.

 *  New: `Cache.initialize()`. Call this on a background thread to eagerly
    initialize the response cache.
 *  New: Fold `MockWebServerRule` into `MockWebServer`. This makes it easier to
    write JUnit tests with `MockWebServer`. The `MockWebServer` library now
    depends on JUnit, though it continues to work with all testing frameworks.
 *  Fix: `FormEncodingBuilder` is now consistent with browsers in which

ですので、実際にコードを読み、実行して確認し、それをコメントで知らせてもらえることが本当に重要です。🤓

### テスト { #tests }

* PRに**テスト**があるか確認を手伝ってください。

* PR前はテストが**失敗**することを確認します。🚨

* そしてPR後にテストが**成功**することを確認します。✅

* 多くのPRにはテストがありません。テストの追加を**リマインド**したり、テストを**提案**したりできます。これは最も時間を消費する部分の一つで、大いに助けになります。

   * All of the infrastructure of split and splitToString is identical, so we do one test of
   * splitToString. All other cases should be covered by testing of split.
   *
   * <p>TODO(user): It would be good to make all the relevant tests run on both split and
   * splitToString automatically.
