如何在 Ballerina 中对 HTTP 服务进行单元测试？

假设我有一个用 Ballerina 编写的 echo HTTP 服务，如下所示：

import ballerina/http;

service / on new http:Listener(9090) {

    resource function post echo(@http:Payload json payload) returns json {
        return payload;
    }
}

如何编写 echo 资源方法的行为单元测试？

Suppose I have an echo HTTP service written in Ballerina as follows:

import ballerina/http;

service / on new http:Listener(9090) {

    resource function post echo(@http:Payload json payload) returns json {
        return payload;
    }
}

How can I write unit test the behavior of the echo resource method?

您可以使用 Ballerina HTTP 客户端为 HTTP 服务编写单元测试。

将测试放在 Ballerina 项目的 tests 目录中。

以下是一个测试示例：

import ballerina/http;
import ballerina/test;

@test:Config {}
function testService() returns error? {
    http:Client httpClient = check new("http://localhost:9090");
    json requestPayload = {message: "hello"};
    http:Request request = new;
    request.setPayload(requestPayload);
    json responsePayload = check httpClient->post("/echo", request);
    test:assertEquals(responsePayload, requestPayload);
}

这里，我们使用 HTTP 客户端发送一个有效负载并取回它，然后检查 echo 服务是否发回相同的有效负载。

运行测试时，该服务将自动启动。您不必手动运行它们。

You can write unit tests for an HTTP service using the Ballerina HTTP client.

Place the tests inside the tests directory inside your Ballerina project.

Following is an example test:

import ballerina/http;
import ballerina/test;

@test:Config {}
function testService() returns error? {
    http:Client httpClient = check new("http://localhost:9090");
    json requestPayload = {message: "hello"};
    http:Request request = new;
    request.setPayload(requestPayload);
    json responsePayload = check httpClient->post("/echo", request);
    test:assertEquals(responsePayload, requestPayload);
}

Here, we send a payload and get it back using an HTTP client, and then check whether the echo service sends back the same payload.

When running the tests, the service will be started automatically. You don't have to run them manually.
