== Requirements
* Java 11
* Maven
* Docker compose
== Building
1 - Start Postgres:
```
docker-compose up
```
2 - Build it, running both unit and integration tests:
```
mvn clean install
```
== Running
1 - Start Postgres if no already started:
```
docker-compose up
```
2 - Run it:
```
mvn compile exec:java
```
=== Transfer test
Open an account 1 with 110.00 and 2 with 0.00 then make a 100.00 transfer from account 1 to 2:
```
docker run --network host -i loadimpact/k6 run - <./k6/transfer.js
```
=== Stress test
Opening many accounts with 1000 virtual users during 60 seconds:
```
docker run --network host -i loadimpact/k6 run --vus 1000 --duration 60s - <./k6/open-many-accounts.js
```
And you will see something like:
