This module integrates mockwebserver3.MockWebServer with JUnit 5.

To use, first add this library as a test dependency:

testImplementation("com.squareup.okhttp3:mockwebserver3-junit5:5.3.0")

Annotate fields in test classes with @StartStop. The server will be started and shut down automatically.

class MyTest {

  @StartStop
  public final MockWebServer server = new MockWebServer();

  @Test
  void test() {
    ...
  }
}

MockWebServer's JUnit 5 integration works on Android 7.0+ (API level 24+) and Java 8+. Note that this is above OkHttp's core requirements.
