量角器:HTTP响应测试 [英] Protractor: HTTP Response Testing

问题描述

我正在使用 Protracotr 进行e2e测试.

I'm using Protracotr for e2e testing.

我想在量角器中测试来自HTTP的响应. 基本上:

I want to test response from HTTP in protractor. Basically:

1. 我已经运行了一些NodeJS服务器.
2. 我想向该服务器发送请求
3. 接收一些JSON数据
4. 解析这些数据
5. 检查它们是否正确

我正在使用"http" NODEJS Lib进行http调用GET + POST.

I'm using "http" NODEJS Lib to make http calls GET+POST.

var http = require('http');

describe("Some test", function() {

    function httpGet(siteUrl) {
        http.get(siteUrl, function(response) {

            response.setEncoding('utf8');
            response.on("data", function(chunk) {
                bodyString += chunk;
            });

            response.on('end', function() {
                defer.fulfill({
                    bodyString: bodyString
                });
            });

        }).on('error', function(e) {
            defer.reject("Got http.get error: " + e.message);
        });

        return defer.promise;
    }

    it('Test case', function(){
        httpGet("http://localhost:3333/path/1/10").then(function(result) {
            var json_data = JSON.parse(result.bodyString);

            for (var i = 0; i < json_data.length; ++i) {
                console.log("label: " + json_data[i].label);
                expect(json_data[i].label).toEqual('abc');
            }
        });
    });
});

我可以在console.log中看到响应消息很好地解析，但是我无法测试任何东西，我的测试结果是:

I can see response message nice parsed in console.log, but I'm not able to test anything, my test results are:

Finished in 0.019 seconds
1 test, 0 assertions, 0 failures

label: Text1
label: Text2

[launcher] 0 instance(s) of WebDriver still running
[launcher] chrome #1 passed

Process finished with exit code 0

测试完成后，控制台日志将被记录下来，并且没有断言.

请提供帮助，如何在Protractor中测试来自服务器的响应(JSON格式)?

Any help please, how to test those responses (in JSON format) from server in Protractor?

推荐答案

对于异步测试，您需要将完成的回调传递给函数.然后，成功调用done()或失败调用done.fail().参见 Jasmine的异步支持文档.

For async tests, you'll need to pass the done callback to your function. Then call done() on success or done.fail() on failure. See Jasmine's Asynchronous support documentation.

it('Test case', function(done){
    httpGet("http://localhost:3333/path/1/10").then((result) => {
        var json_data = JSON.parse(result.bodyString);

        for (var i = 0; i < json_data.length; ++i) {
            console.log("label: " + json_data[i].label);
        }
        done();
    }).catch(err => {
        done.fail();
    });
});
