HandshakeCertificates serverCertificates = new HandshakeCertificates.Builder()
    .heldCertificate(localhostCertificate)

MockWebServer server = new MockWebServer();
server.useHttps(serverCertificates.sslSocketFactory(), false);
```

`HandshakeCertificates` also works for clients where its job is to define which root certificates

MockWebServer is used for firstly for internal testing, and for basic testing of apps using OkHttp client.
It is not a full featured HTTP testing library that is developed standalone. It is not being actively developed
