Question

我收到以下错误...

Cannot get property 'grails' on null object
java.lang.NullPointerException: Cannot get property 'grails' on null object
    at pcc.EmailSharerController.<init>(EmailSharerController.groovy)
    at grails.test.MvcUnitTestCase.newInstance(MvcUnitTestCase.groovy:102)
    at grails.test.ControllerUnitTestCase.super$6$newInstance(ControllerUnitTestCase.groovy)
    at grails.test.ControllerUnitTestCase.newInstance(ControllerUnitTestCase.groovy:112)
    at grails.test.ControllerUnitTestCase.setUp(ControllerUnitTestCase.groovy:55)
    at pcc.EmailSharerControllerTests.super$7$setUp(EmailSharerControllerTests.groovy)
    at pcc.EmailSharerControllerTests.setUp(EmailSharerControllerTests.groovy:12)

...当我运行EmailSharerController的单元测试setUp（）时，即使它被缩减为：

protected void setUp() {
        super.setUp()  
}

我浏览过网络但一无所获。我不知道它会来自哪里。任何帮助都极大地促成了:)

问题是Grails在单元测试中不支持ConfigurationHolder对象。可以这样解决：

mockConfig("""  
        grails {
            serverURL = 'my domain name'
        }
    """)

例如，

调用Config.groovy的grails.serverURL属性。

Grails - “无法从单元测试中获取null对象上的属性'grails'”
