junit - 作为 IntelliJ IDEA JUnit 运行配置运行 playframework 测试

Question

我一直在尝试直接从内置测试运行器中运行 IntelliJ Play 应用程序中的单元测试。 (要获得漂亮的用户界面，请点击等)

这适用于非常基本的 FunctionalTest 测试，当它启动时，它会提供以下日志记录:

16:18:08,353 INFO  ~ Starting /home/sindrit/projects/testapp/.
16:18:08,370 INFO  ~ Module crud is available (/home/sindrit/play-1.2.3/modules/crud)
16:18:08,949 WARN  ~ You're running Play! in DEV mode
16:18:10,242 INFO  ~ Connected to jdbc:h2:mem:play;MODE=MYSQL;LOCK_MODE=0
16:18:11,033 INFO  ~ Application 'testapp' is now started !

表示游戏开始了。

然而，使用数据库访问的更复杂的测试会失败，并出现如下异常:

我预计这是因为仪器无法像运行游戏时那样工作。相同的测试在 play auto-test 中运行良好。

通过一些谷歌搜索，我发现我至少需要以下参数:

• -javaagent:/home/sindrit/play-1.2.3/framework/play-1.2.3.jar
• -Dfile.encoding=utf-8
• -Dplay.debug=yes
• -Dplay.id=test
• -Dapplication.path=/home/sindrit/projects/testapp

这里有人让这个工作吗？

我需要哪些 JVM 参数或类路径或其他东西才能使 IntelliJ 测试运行器模拟游戏运行时环境？

如果我将 play-testrunner.jar 添加到依赖项中，我会收到以下错误:

我可能过度简化了这一点，但您似乎忘记了数据库模型上的实体注释。

您的模型应如下所示。

@Entity
@Table( name = "pkg_load" )
public class PkgLoad extends Model {

}

或者，如果您不想在模型中使用内置 ID。

    @Entity
@Table( name = "pkg_load" )
public class PkgLoad extends GenericModel {

    @Id
    @GeneratedValue( strategy = GenerationType.IDENTITY )
    @Basic( optional = false )
    @Column( name = "pkg_load_id" )
    public Long pkgLoadId;
}

http://www.playframework.org/documentation/1.2.3/jpa

实体注释位于 javax.persistence 库中。
