# What it looks like
# Quick Start

Assume we have a basic JAX-RS application that can perform create, update, and delete
operations on 'Person' data objects. It may look something like this:
To get started writing a test with MicroShed Testing, add `system-test` and `junit-jupiter` as test-scoped dependencies:

```java
@Path("/people")
@ApplicationScoped
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class PersonService {

private final PersonRepo personRepo = // ...

@GET
public Collection<Person> getAllPeople() {
return personRepo.values();
}

@GET
@Path("/{personId}")
public Person getPerson(@PathParam("personId") long id) {
Person foundPerson = personRepo.get(id);
if (foundPerson == null)
throw new NotFoundException("Person with id " + id + " not found.");
return foundPerson;
}

// ...
}
```xml
<dependency>
<groupId>org.microshed</groupId>
<artifactId>microshed-testing-testcontainers</artifactId>
<version>0.9.2</version>
<scope>test</scope>
</dependency>

<!-- Any compatible version of JUnit Jupiter 5.X will work -->
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter</artifactId>
<version>5.10.1</version>
<scope>test</scope>
</dependency>
```

Using MicroShed Testing, we can write an integration test that looks something like this:
Once you have the above dependencies added, create a new test class with the following items:
1. Annotate the class with `@MicroShedTest`
1. Create a `public static ApplicationContainer` field
1. Inject one or more `public static` JAX-RS resource classes

```java
import static org.junit.jupiter.api.Assertions.*;
import javax.ws.rs.NotFoundException;
import org.junit.jupiter.api.Test;
import org.microshed.testing.jaxrs.RESTClient;
import org.microshed.testing.jupiter.MicroShedTest;
import org.microshed.testing.testcontainers.ApplicationContainer;
import org.testcontainers.junit.jupiter.Container;

@MicroShedTest
public class BasicJAXRSServiceTest {
public class MyTest {

// This will search for a Dockerfile in the repository and start up the application
// in a Docker container, and wait for it to be ready before starting the tests.
@Container
public static ApplicationContainer app = new ApplicationContainer()
.withAppContextRoot("/myservice");

// This injects a REST _Client_ proxy of the PersonService shown above
// This allows us to easily invoke HTTP requests on the running application container

@RESTClient
public static PersonService personSvc;

@Test
public void testGetPerson() {
// This invokes an HTTP POST request to the running container, which triggers
// the PersonService#createPerson endpoint and returns the generated ID
Long bobId = personSvc.createPerson("Bob", 24);

// Using the generated ID, invoke an HTTP GET request to read the record we just created
// The JSON response will be automatically converted to a 'Person' object using JSON-B
Person bob = personSvc.getPerson(bobId);

assertEquals("Bob", bob.name);
assertEquals(24, bob.age);
assertNotNull(bob.id);
}
public static MyService mySvc;

@Test
public void testGetUnknownPerson() {
// This invokes an HTTP GET request to get a person with ID -1, which does not exist
// asserts that the application container returns an HTTP 404 (not found) exception
assertThrows(NotFoundException.class, () -> personSvc.getPerson(-1L));
}

// ...
// write @Test methods as normal
}
```

If the repository containing the tests does not have a `Dockerfile` in it, there are a few other options:

* If the application's container image is produced by a different repository, a String docker image label can be
supplied instead:

```java
@Container
public static ApplicationContainer app = new ApplicationContainer("myservice:latest")
.withAppContextRoot("/myservice");
```
* If a Dockerfile or container image label is not available, it is possible to use vendor-specific adapters that will
provide the default logic for building an application container. For example, the `microshed-testing-liberty` adapter will
automatically produce a testable container image roughly equivalent to the following Dockerfile:

```
FROM openliberty/open-liberty:full-java17-openj9-ubi
COPY src/main/liberty/config /config/
ADD target/$APP_FILE /config/dropins
```
