Mockito. Is it possible to lock a method call inside another method?

Question

Java

There is an endpoint:

@PostMapping("/some/endpoint")
    public void storeData(@Valid @RequestBody SomeMessageDTO data) {
        UUID id = data.getDeviceId();
        validateDeviceAccess(id);
        this.saveData(data);
    }

The called validateDeviceAccess method throws an exception if the device with the passed id is inactive. If active, then control is transferred to this.saveData(data);

Question: Is it possible to simulate throwing an exception using the validateDeviceAccess method using Mockito?

Answer 1

You can use spy .
