How to bypass SSL handshake for SSLContext?

I am modifying a test which previously used a HTTP call to an external api. There is a new endpoint which now uses HTTPS and so I am trying to modify the test to be able to work with this.

The issue im facing is that I'm getting a handshake error when trying to run the test.

the base boilerplate is:

@Testpublic void testApi() throws Exception {  MockWebServer mockWebServer = new MockWebServer();    // Begin new code    SSLContext sslContext = SSLContext.getInstance("TLS");    sslContext.init(null, null, null);    SSLSocketFactory socketFactory = sslContext.getSocketFactory();    mockWebServer.useHttps(socketFactory, false);    // End new code    mockWebServer.enqueue(new MockResponse().setBody("{}").setHeader("Content-Type", "application/json"));    mockWebServer.play();    FooCaller fooCaller = new FooCaller();    fooCaller.postRequest("jsonString");    RecordedRequest request = mockWebServer.takeRequest();//Assertions on request...}

Unfortunately I don't have access to create a local certificate or key/truststore so I can't initialise the SSL context's KeyStoreManager and TrustStoreManager with anything other than null. Is there a way to bypass this handshake or to bypass the authentication?

(notes:

1. I'm using com.google.mockwebserver not the newer okhttp version
2. the code that inside the // Begin new code - End new code comments is the only new code and the test was working with the http call before switching to https)
