1. Create database user
```shell
createuser -P test_user
```
```shell
createuser -P test_user
```
Enter a password of your choice. The following instructions assume you
used `testing` as password.
Enter a password of your choice. The following instructions assume you used `testing` as password.
This step is **optional** and you can also use an existing database user
for that. Just make sure to replace `test_user` by the database user
of your choice in the following steps and change the `.env` file
containing the configuration accordingly.

2. Create database
```shell
createdb -O test_user testing_db
```
```shell
createdb -O test_user testing_db
```
3. Initialize database
```shell
psql -f sql/schema.sql testing_db
```
```shell
psql -f sql/schema.sql testing_db
```
This step can be repeated and clears the database as it drops and
recreates the schema `testing` which is used within the database.

4. Create `.env` file:
```ini
SERVER_ADDR=127.0.0.1:8080
PG.USER=test_user
PG.PASSWORD=testing
PG.HOST=127.0.0.1
PG.PORT=5432
PG.DBNAME=testing_db
PG.POOL.MAX_SIZE=16
```
```ini
SERVER_ADDR=127.0.0.1:8080
PG.USER=test_user
PG.PASSWORD=testing
PG.HOST=127.0.0.1
PG.PORT=5432
PG.DBNAME=testing_db
PG.POOL.MAX_SIZE=16
```
5. Run the server:
```shell
cargo run
```
```shell
cargo run
```
6. Using a different terminal send an HTTP POST request to the running server:
```shell
echo '{"email": "ferris@thecrab.com", "first_name": "ferris", "last_name": "crab", "username": "ferreal"}' | http -f --json --print h POST http://127.0.0.1:8080/users
```
```shell
echo '{"email": "ferris@thecrab.com", "first_name": "ferris", "last_name": "crab", "username": "ferreal"}' | http -f --json --print h POST http://127.0.0.1:8080/users
```
**...or using curl...**
**...or using curl...**
```shell
curl -d '{"email": "ferris@thecrab.com", "first_name": "ferris", "last_name": "crab", "username": "ferreal"}' -H 'Content-Type: application/json' http://127.0.0.1:8080/users
```
```shell

```
A unique constraint exists for username, so sending this request twice
will return an internal server error (HTTP 500).
