为了实现这个班级管理系统的测试用例，我们可以在 Java 中使用 JUnit 测试框架，以及 HttpClient 库来模拟客户端与服务器的交互。
- 定义客户端类
首先，我们需要定义一个 Client 类，用于封装 HTTP 请求操作：
public class Client {
private String url;
public Client(String url) {
this.url = url;
}
public HttpResponse post(String path, Map<String, Object> params) throws IOException {
HttpPost request = new HttpPost(url + path);
return execute(request, params);
}
public HttpResponse get(String path) throws IOException {
HttpGet request = new HttpGet(url + path);
return execute(request, null);
}
public HttpResponse put(String path, Map<String, Object> params) throws IOException {
HttpPut request = new HttpPut(url + path);
return execute(request, params);
}
public HttpResponse delete(String path) throws IOException {
HttpDelete request = new HttpDelete(url + path);
return execute(request, null);
}
private HttpResponse execute(HttpRequestBase request, Map<String, Object> params) throws IOException {
HttpClient client = HttpClientBuilder.create().build();
if (params != null) {
List<NameValuePair> pairs = new ArrayList<>();
for (Map.Entry<String, Object> entry : params.entrySet()) {
pairs.add(new BasicNameValuePair(entry.getKey(), String.valueOf(entry.getValue())));
}
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs, StandardCharsets.UTF_8);
request.setEntity(entity);
}
HttpResponse response = client.execute(request);
return response;
}
}
- 编写测试用例
接着，我们可以编写测试用例：
- 创建新班级：
```scss
@Test
public void testCreateClassroom(Client client) throws IOException {
Map data = new HashMap<>();
data.put("name", "class1");
HttpResponse response = client.post("/classroom", data);
assertEquals(response.getStatusLine().getStatusCode(), 200);
assertEquals(response.getEntity().getContent(), "class1".getBytes());
}
