It would be really nice to have ability to somehow swap defaultHttpClient: okhttp3.Call.Factory with Mock Entity in tests. For now current implementation of functions like httpGet {} can be only tested by using MockWebServer from okhttp or you have to inject okhttp3.Call.Factory manually.

Ideally i would like to have integration with mockk, because it's designated mocking framework for kotlin.

Example:

@EnableOkHttpMock
class MyTest {
    
    private val sut = MyBestService()
    
    fun `test foo is bar`() {
        //given
        every { httpGet(any()) } returns "foo" to "bar"
        
        //when
        val res = sut.getBar()
        
        //then
        assert("bar", res)
    }
}
