如何在空手道中添加条件等待响应？

提问于

对于我们的DELETE请求之一，请求时间超过30秒 . 如果超过30秒，测试有时会失败 . 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 . 但我想在GET调用中检查一些条件，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，只有在传递'delete'调用时才会调用'waitUntil' .

但我只想在DELETE呼叫响应失败/超过30秒时调用'waituntil'

我跟着How to retry a request until i get a valid dynamically generated value in response using karate dsl

但没有多大帮助

    根据您的问题，我相信您正在尝试进行DELETE调用（用于删除某些记录），然后进行GET调用（以验证该记录是否已删除） .

    从您的示例：删除“MyKarateSoap”记录并验证“MyKarateSoap”== null

    Answer 1: 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删除调用来本地调整连接和读取超时，

    * configure connectTimeout = 30000    
* configure readTimeout = 30000

    这种配置会让空手道等待30秒然后再输出任何失败 . （仅当您提到的故障是由请求的连接或响应超时引起时）

    通过反复试验选择最佳超时（或者从POSTMAN或浏览器中执行相同操作并获取平均响应时间）

    Answer 2:

    您的删除服务可能会按预期响应，但有时系统中可能存在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

    这应该每隔5秒汇集一次获取服务，直到它超过您的输入时间 .
