Mock new object creation Mockito without PowerMock

Question

I have a say SomeResolver whose method resolve I need to test. The method is creating a new object which I am trying to mock. Something like below

public class SomeResolver {
  public String resolve() {
    // need to mock this
    OkHttpClient client = new OkHttpClient().newBuilder().build();
   // so that this
   Response response = client.newCall(someRequest).execute();
   // returns a response I want.
   ...
  }
}

My Test Class SomeResolverTest can mock final classes and uses Mockito v3.9.0 but I cannot add the Powermock dependency

Is there a way I can mock the value returned by new?

Answer 1

The answer by @Vitor Cavalcanti is good one but for this specific use case, I am better off using the mockwebserver library provided by OkHttp

<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>mockwebserver</artifactId>
    <version>${okhttp.version}</version>
    <scope>test</scope>
</dependency>

Because once I keep adding tests I will need to mock a lot of classes related to the web server and this dependency does that for me.
