# DolphinScheduler Backend API Test
## Page Object Model
DolphinScheduler API test respects
the [Page Object Model (POM)](https://www.selenium.dev/documentation/guidelines/page_object_models/) design pattern.
Every page of DolphinScheduler's api is abstracted into a class for better maintainability.
### Example
The login page's api is abstracted
as [`LoginPage`](dolphinscheduler-api-test-case/src/test/java/org/apache/dolphinscheduler/api.test/pages/LoginPage.java), with the
following fields,
```java
public HttpResponse login(String username, String password) {
Map<String, Object> params = new HashMap<>();
params.put("userName", username);
params.put("userPassword", password);
RequestClient requestClient = new RequestClient();
return requestClient.post("/login", null, params);
}
```
where `userName`, `userPassword` are the main elements on UI that we are interested in.
## Test Environment Setup
DolphinScheduler API test uses [testcontainers](https://www.testcontainers.org) to set up the testing
environment, with docker compose.
Typically, every test case needs one or more `docker-compose.yaml` files to set up all needed components, and expose the
DolphinScheduler UI port for testing. You can use `@DolphinScheduler(composeFiles = "")` and pass
the `docker-compose.yaml` files to automatically set up the environment in the test class.
```java
@DolphinScheduler(composeFiles = "docker/tenant/docker-compose.yaml")
class TenantAPITest {
}
```
