JS磁带 - 等待以前的异步测试完成移动到下一个测试

Question

我是新来的与TAPE JS工作测试。我已经完成了所有设置和工作，并且它可以在常规测试中正常工作。但是我试图测试一个独特的基于REST API的产品，它依靠在下一次调用之前已经完成的某些调用而获得了成功调用所需的信息。

因此，这里是前两个电话，我试图让工作：

var SessionId; 

test('beginIqsSession', function (assert) { 
    assert.plan(1); 
    var requestData = {"ProductDataArray":{"Feid":"GIQNY","AltData":"SaneID:null","Debug":"false","PageId":"1.1"}}; 

    request({ 
    url: 'http://192.168.99.100/Iqs/api.php/beginIqsSession', 
    method: "POST", 
    json: requestData 
    }, function(error, response, json){ 

     if(json.responseDataPayload.SessionId) 
     { 
      SessionId = json.responseDataPayload.SessionId; 

      assert.equal(1,1); 
     } 
    }); 
    assert.end(); 
}); 


test('validateAddress', function (assert) { 
    assert.plan(2); 

    console.log("Retrieving validateAddress response"); 

    var requestData = {"SessionId":SessionId,"ValidateAddressDataArray":{"PropertyStreetNumber":"20671","PropertyStreetName":"mountain vista dr","PropertyCity":"anchorage","PropertyState":"AK","PropertyZipCode":"99577"}}; 

    console.log(SessionId); 

    request({ 
     url: 'http://192.168.99.100/Iqs/api.php/validateAddress', 
     method: "POST", 
     json: requestData 
    }, function (error, response, body) { 

     if (!error) { 
      console.log(body); 
     } 
     else { 
      console.log("error: " + error) 
     } 
    }); 

    assert.end(); 
}); 

所以基本上在上面的代码中，我试图测试beginIqsSession，等待它的响应，并存储一个数据从未来电话需要发送的响应。

in validateAddress您会看到我正在尝试传递其中前一个调用返回的SessionId，但因为此测试正在同时运行以前的测试中，这个变量仍然是空的。如何让第二个电话和所有将来的电话等待上一个电话的运行？

assert.plan显然不能以这种方式工作。

您可以使用Promise API

var SessionId; 
 

 
let p1 = new Promise((resolve, reject) => { 
 
    test('beginIqsSession', function (assert) { 
 
    assert.plan(1); 
 
    var requestData = {"ProductDataArray":{"Feid":"GIQNY","AltData":"SaneID:null","Debug":"false","PageId":"1.1"}}; 
 

 
    request({ 
 
    url: 'http://192.168.99.100/Iqs/api.php/beginIqsSession', 
 
    method: "POST", 
 
    json: requestData 
 
    }, function(error, response, json){ 
 

 
     if(json.responseDataPayload.SessionId) 
 
     { 
 
      SessionId = json.responseDataPayload.SessionId; 
 

 
      assert.equal(1,1); 
 
      resolve(SessionId); 
 
     } 
 
    }); 
 
    assert.end(); 
 
    }); 
 
}) 
 

 
p1.then((SessionId) => { 
 
    test('validateAddress', function (assert) { 
 
    assert.plan(2); 
 

 
    console.log("Retrieving validateAddress response"); 
 

 
    var requestData = {"SessionId":SessionId,"ValidateAddressDataArray":{"PropertyStreetNumber":"20671","PropertyStreetName":"mountain vista dr","PropertyCity":"anchorage","PropertyState":"AK","PropertyZipCode":"99577"}}; 
 

 
    console.log(SessionId); 
 

 
    request({ 
 
     url: 'http://192.168.99.100/Iqs/api.php/validateAddress', 
 
     method: "POST", 
 
     json: requestData 
 
    }, function (error, response, body) { 
 

 
     if (!error) { 
 
      console.log(body); 
 
     } 
 
     else { 
 
      console.log("error: " + error) 
 
     } 
 
    }); 
 

 
    assert.end(); 
 
    }); 
 
    
 
});
