Grails 3.3.8 单元测试服务

Question

我正在尝试测试使用 src/main/webapp/folder 下的文件的服务方法，但是它不起作用，由于任何原因它似乎没有访问权限或其他什么，获取文件的代码是以下：

def file = grailsApplication.parentContext.getResource("folder/file.txt").file

错误是：

ServletContext resource [/folder/file.txt] cannot be resolved to absolute file path - web application archive not expanded?

有什么想法吗？ 这不是 grailsApplication 注入或获取资源方法，我认为该服务在被测试框架使用时无权访问该路径。

line number one
line number two
line number three

https://github.com/jeffbrown/davidpadillaservice/blob/master/grails-app/services/davidpadillaservice/SomeResourceService.groovy

package davidpadillaservice

import org.springframework.beans.factory.annotation.Value
import org.springframework.core.io.Resource

class SomeResourceService {

    @Value("classpath:folder/file.txt")
    Resource fileResource

    String getFirstLine() {
        getLine(0)
    }

    String getSecondLine() {
        getLine(1)
    }

    protected String getLine(int index) {
        fileResource.file.readLines().get(index)
    }
}

https://github.com/jeffbrown/davidpadillaservice/blob/master/src/test/groovy/davidpadillaservice/SomeResourceServiceSpec.groovy

package davidpadillaservice

import grails.testing.services.ServiceUnitTest
import spock.lang.Specification

class SomeResourceServiceSpec extends Specification implements ServiceUnitTest<SomeResourceService>{

    void "test interacting with the service"() {
        expect:
        service.firstLine == 'line number one'
        service.secondLine == 'line number two'
    }
}

希望对你有帮助。
