如何在空手道中添加条件等待响应？

Question

我们的一个 DELETE 请求花费的时间超过 30 秒。如果花费超过 30 秒，有时测试会失败。我需要添加等待响应，直到某些 GET 调用通过。我试过下面的代码。但是我想检查 GET 调用中的某些条件，然后我想断言 DELETE 调用。

 Feature:       

Background:
* def waitUntil = 
"""
function(x) {
  while (true) {

    var result = karate.call('classpath:ic/feature/soap/Common/getApplicationsList.feature');
    var res = result.response;
    karate.log('poll response in side java script', res.integration.serviceData.applicationsList.WmSOAPProvider['MyKarateSoap']);

    karate.log('Actual responseis in jacva script ---> ', res.integration.serviceData.applicationsList.WmSOAPProvider)
    var local = res.integration.serviceData.applicationsList.WmSOAPProvider['MyKarateSoap'];
    karate.log('local value is--->' +local)

    karate.log('res is ----->' +res)
    if (res.integration.serviceData.applicationsList.WmSOAPProvider['MyKarateSoap'] == null) {
      karate.log('condition satisfied, exiting');
      return;
    }
    karate.log('sleeping in else block');
    // uncomment / modify the sleep time as per your wish
    java.lang.Thread.sleep(3000);
  }
}
"""

Scenario: delete soap application

Given url appServer
And path '/integration/rest/application/WmSOAPProvider/' +'MyKarateSoap'

And header Accept = 'application/json'
And header Content-Type = 'application/json'
And header X-CSRF-TOKEN = lresult.response.csrfToken
* cookie JSESSIONID = lresult.responseCookies.JSESSIONID.value
* cookie route = lresult.responseCookies.route.value

When method delete

* call waitUntil 200

在上面的代码中 'waitUntil' 仅在 'delete' 调用通过时被调用。

但我只想在 DELETE 调用响应 failed/took 超过 30 秒时调用 'waituntil'

我关注了

但帮助不大

Answer 1

根据你的问题，我认为你正在尝试进行 DELETE 调用（用于删除某些记录），然后进行 GET 调用（用于验证记录是否已删除）。

从你的例子来看：删除 'MyKarateSoap' 记录并验证 'MyKarateSoap' == null

答案一： 如果您的删除服务需要更多时间来响应，您可以通过将此添加到您的删除调用来本地调整连接和读取超时，

* configure connectTimeout = 30000    
* configure readTimeout = 30000

此配置会让空手道等待 30 秒，然后再抛出任何故障。（仅当您提到的失败是由请求的连接或响应超时引起的）

通过反复试验选择最佳超时（或从 POSTMAN 或您的浏览器中执行相同的操作并获取平均响应时间）

答案2：

您的删除服务可能会按预期响应，但有时系统中可能会出现延迟以反映您的删除，这可能会导致您的 GET 调用失败，如果是这种情况，您可以使用类似下面的逻辑进行池化

* def waitUntil =
"""
function(waitTime) {
    var poolTime = 5;
    var counter = 1;
    // should pool for every 5 seconds until it exceeds your input wait time
    while (true) {
        if( (counter*poolTime) > waitTime){
            karate.log('condition not satisfied for a long time, exiting');
            return false;
        }
        var result = karate.call('getApplicationsList.feature');
        var WmSOAPProvider = result.response.integration.serviceData.applicationsList.WmSOAPProvider
        if (WmSOAPProvider['MyKarateSoap']) {
            karate.log('condition satisfied, exiting');
            return true;
        }
        // pool every 5 seconds
        java.lang.Thread.sleep(poolTime*1000);
        counter++;
    }
};
"""
* def result = waitUntil(30)
* def assert result == true

这应该每 5 秒汇集一次获取服务，直到超过您输入的时间。
