空手道：[main] INFO com.intuit.karate - karate.env系统属性是: null

Question

当尝试使用生成的令牌获取错误执行下一个场景时，令牌身份验证流：

main INFO com.intuit.karate - karate system属性为: null

我使用了以下代码：

特性文件：

Feature: Login Token Authentication http://symex.dyndns.org:6586/
Background: url 'http://symex.dyndns.org:6586/'
Scenario: Token Authentication flow

* path 'token'
* form field grant_type = 'password'
* form field client_id = 'demoapp'
* form field client_secret = 'demopass'
* form field username = 'xxxx
* form field password = 'xxxx'
* method post
* status 200

* def accessToken = response.access_token

Scenario: ForeignCurrencyStockBalance

* path 'api/v1/ForeignCurrencyStockBalance'
* header Authorization = 'Bearer ' + accessToken
# * param access_token = accessToken
* method GET
* status 200

runner类：

package Runner;

import com.intuit.karate.junit4.Karate;
import com.intuit.karate.KarateOptions;

import org.junit.runner.RunWith;

@RunWith(Karate.class)
@KarateOptions(features = "classpath:Runner/login.feature")
public class LoginRunner{}

Karate-config.js

function() {
  var env = karate.env; // get system property 'karate.env'
  karate.log('karate.env system property was:', env);
  karate.configure("ssl", true)
  if (!env) {
    env = 'qa';
  }
  var config = {
    env: env,

  }
  if (env == 'dev') {
    // customize
    // e.g. config.foo = 'bar';
  } else if (env == 'e2e') {
    // customize
  }
  return config;
}

备注：成功执行令牌身份验证流

预期的：应该将令牌存储在变量中并执行下一个场景

实际：获取错误信息com.intuit.karate -空手道系统属性是: null

Answer 1

INFO com.intuit.karate - karate.env系统属性为: null

是由于Karate-config.js中的代码而收到的消息。

karate.log('karate.env system property was:', env);

如果您将maven命令作为

mvn test -Dkarate.env=e2e

你会得到这样的

INFO com.intuit.karate - karate.env system property was: e2e。

，但这不能解决accessToken的问题。正如here by Peter Thomas所解释的那样，这些场景应该独立运行。

每个场景都应该能够独立运行。

您可以在分离的特性中定义身份验证，并在需要时调用它，如

Scenario: ForeignCurrencyStockBalance
* path 'api/v1/ForeignCurrencyStockBalance'
* def authentication = read('classpath:authentication.feature')
* def userLogin = call authentication
* header Authorization = 'Bearer ' + userLogin.access_token
* method GET
* status 200
