Did you mean deterministic?

[@Anon-jz7iw]

I think so, google is saying deterministic is the correct wording.

[@mattcummings737]

Great videos! Quick nerd note, I believe that the logic is inverted on the way you described non-deterministic. The way you described how we want unit test to have stable and reproducible output is deterministic.

[@alma89732]

Man your explanation was so good and helped me to understand perfectly what I had to do. Really really thank you, I had been struggling with this for a while and you saved me!

[@piotrjaga6929]

Did you mean non-random? because you said non-deterministic is when you always get the same result for the same input, but this is fully deterministic then

[@lenigaussgauss2428]

You well explained the principal of Mockito but didn't explained how each of them works. When do we need to use Mockito.any(...), mockito.mock(...), when()... And what does all these methods do ?

[@luishenriquedossantos8183]

This is gold man, thank you so much

[@jonastimo6582]

great video, thank you! That was very helpful. One question though: You have been injecting the implementation of pokemonService. Does it have to be the class? Could we possibly use the interface instead and have mockito decide which class to use (maybe with some attribute added for specification, in case there is more than one implementation around)? e. g. Spring Autowiring would allow doing so

[@Vedant-ts2gf]

In test environment springboot don't provide the functionality of dependency injection. so for that you will need to add annotations over class. (i.e @SpringBootTest & @RunWith(SpringRunner.class)).

This is top notch content. Thanks. Can you please cover all this in more detail? I would appreciate if you can cover Integration testing as well. Please take some common examples like Students or Employee.

[@TeddySmithDev]

Yes, I’m in C# right now but once done will be back in Java. Thanks for commenting!

[@martinmatovcik7918]

Really good explanation! thanks😉

[@daoudasylla91]

Thx you man. What application do you use for your note ? I like the hand writer

[@tharlinhtet97]

when(pokemonRepository.save(Mockito.any(Pokemon.class))).thenReturn(pokemon) how come this test case can be passed? pokemon object is built using builder pattern.

Thx dude , really appreciate it
