我正在尝试在Grails中创建我的第一个集成测试。为此，我执行了grails create-integration-test MyClass，它创建了一个空的IT。这是它的样子：
import grails.test.mixin.integration.Integration
import grails.transaction.Rollback
import spock.lang.Specification
@Integration
@Rollback
class MyClassSpec extends Specification {
def setup() {
}
def cleanup() {
}
void "test something"() {
expect: "fix me"
true == false
}
}
当我使用grails test-app -integration运行测试时，它不会抱怨true==false，但会给我这个错误：

我猜测Grails无法以某种方式连接到数据库。我是否必须在application.yml添加内容，我已存储了我的数据库连接信息？或者我错过了其他什么？
顺便说一句：我的Grails应用程序在执行IT时使用grails run-app运行，我正在使用Grails 3.0.9。

更新2：
我似乎可以手动运行IT（使用IntelliJ Idea），但不能运行grails test-app。
答案 0 :(得分：4)
您application.yml文件在url环境的dataSource配置中不包含test，导致在配置数据库连接设置时hibernate失败。
如果您计划在那里运行应用程序，则需要为测试或生产等其他环境添加配置详细信息。
