空手道 karate-config.js 不是 js 函数

Question

我正在尝试使用空手道进行 e2e 测试，并从最小设置开始。我想在karate-config.js 中创建一些配置项以用于测试，但空手道报告该文件不是 js 函数，因此尝试获取配置时测试失败：

Warning: Nashorn engine is planned to be removed from a future JDK release
12:16:35.264 [Test worker] WARN com.intuit.karate - not a js function or feature file: read('classpath:karate-config.js') - [type: NULL, value: null]

org.opentest4j.AssertionFailedError: -unknown-:4 - javascript evaluation failed: priceBaseUrl, ReferenceError: "priceBaseUrl" is not defined in <eval> at line number 1

这是我的karate-config.js：

function fn() {

    return {
        priceBaseUrl: "http://localhost:8080"
    };
}

这是我的insurer.feature 测试：

Feature: which creates insurers

Background:
  * url priceBaseUrl
  * configure logPrettyRequest = true
  * configure logPrettyResponse = true

Scenario: basic roundtrip 

# create a new insurer
Given path 'insurers'
And request { name: 'Sammy Insurance', companyCode: '99' }
When method post
Then status 201
And match response == { resourceId: '#number', version: 0, createdBy: 'anonymousUser' }

* def insurerId = response.resourceId

# get insurer by resource id
Given path 'insurers', insurerId
When method get
Then status 200
And match response == { id: '#(id)', name: 'Sammy Insurance', companyCode: '99' }

这是InsurerTest.java 测试运行器：

package karate;

import com.intuit.karate.junit5.Karate;

class InsurerTest {

    @Karate.Test
    public Karate testInsurer() {
        return new Karate().feature("classpath:karate/insurer.feature");
    }
}

Answer 1

请在 karate-config.js 中使用以下代码

function() {    
    return priceBaseUrl='http://localhost:8080';
}

Answer 2

当我看到这个时：

Warning: Nashorn engine is planned to be removed from a future JDK release

我怀疑您使用的是 Java 9 或 11？老实说，我们还没有在这些 Java 版本上完全测试空手道。您是否可以确认 Java 8（也可能是 9 / 10）是可以的。

也就是说，我们有兴趣尽快解决此问题，因此，如果您可以提交一个示例项目，我们可以复制此问题，请这样做：https://github.com/intuit/karate/wiki/How-to-Submit-an-Issue

编辑：Karate 1.0 将使用 GraalVM 而不是 Nashorn，甚至可以在 JDK 16 上运行：https://software-that-matters.com/2021/01/27/7-new-features-in-karate-test-automation-version-1_0/
