FIRST things first

Fast Run more oftenIsolated Can be executed in any orderRepeatable Always return the same resultSelf-Validating Know exactly their purposeTimely Run before code

Bartosz Majsak

I'm not sure if these titles are of any help

Bartosz Majsak

From where do we have explanation for this points? What would like to say here?

Bartosz Majsak

The look&feel is not final, however you can change it as you want

Alex Soto

I will start saying that before starting on persistence test 2 minutes of theory, and all tests in general and unit tests in particular should follow the FIRST rule

Frequently omitted rules

in Persistence tests

FAST

Fast

FAST

Network access

Long bootstrap

Humongous amount of data

Bartosz Majsak

Final transitions at the end of the process :)

FAST

HSQLDB

MongoDB (fongo)

Neo4J

Cassandra

Infinispan

HBase

Isolation

Bartosz Majsak

You can talk about isolation as you know better nosql areaI can mentioned about per-dev schemas and cleanup strategies as a remark

ISOLATION

public class BeerRepositoryTest {

BeerRepository beerRepository;

@Test public void should_persist_beer() { beerRepository.save(new Beer(“Mocny Full”)); }

@Test public void should_count_beers() { int beers = beerRepository.count(); assertThat(beers).isEqualTo(??); }

}

Bartosz Majsak

as with the previous one - coloring as final touch

Bartosz Majsak

it will based on the Arquillian example, but I will take care of it tomorrow

Alex Soto

I think it is enough

ISOLATION

DBUnit

Unitils

NoSQLUnit

Arquillian Persistence Extension

Bartosz Majsak

I thought maybe we break it down to problem-solution

Alex Soto

I think that this slide should go after isolation because the isolation are acquired by these tools, fast is acquired by using embedded db

Bartosz Majsak

correct! my fault

Bartosz Majsak

But then you talk about FAST and I talk about isolation

Alex Soto

Om perfect I will start talking about FIRST and Fast, then you talk about Isolation and the beer and dbunit
