如何在Play框架单元测试中加载不同的插件？ [英] How to load different plugins in Play framework unit tests?

问题描述

我有不同的插件实现了插件界面。现在我把它们硬编码在play.plugins中这样：

I have different plugins implemented the Plugin interface. Now I have them hard-coded in play.plugins like this:

100:test.A
200:test.B

但在我的单元测试中，我不希望一次加载它们。换句话说，在测试A中我只想加载插件A而在测试B中只加载B.而不是手动更改配置文件，有没有办法以编程方式更改它？我想当调用 fakeApplication（）时，默认情况下会加载所有插件。

However in my unit tests I don't want both of them to be loaded at one time. In other words, in test A I want to load only plugin A and in test B load B only. Instead of changing the configuration file manually, is there a way to change it programmatically? I guess when fakeApplication() is invoked all plugins are loaded by default.

推荐答案

您可以使用添加或排除的插件启动 FakeApplication 使用自定义配置。

You can start a FakeApplication with added or excluded plugins and also with custom configuration.

这是scala中的一个例子（我相信Java API有一个等效的机制）：

Here is an example in scala (I believe the Java API has an equivalent mechanism) :

val app = FakeApplication(  
  withoutPlugins = List("test.A", "test.B"),  
  additionalPlugins = List("test.C"),  
  additionalConfiguration = Map("customConfigKey" -> "customConfigValue")  
)

在Java中，您可以使用 play.test.Helpers 类中提供的 fakeApplication 静态方法之一。这是scala示例的等价物：

In Java, you can use one of the fakeApplication static methods available in the play.test.Helpers class. Here is the equivalent of the scala example :

import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
import java.util.List;
import play.test.FakeApplication;
import static play.test.Helpers.*;

Map<String, Object> additionalConfiguration = new HashMap<String, Object>();
additionalConfiguration.put("customConfigKey", "customConfigValue");
List<String> withoutPlugins = Arrays.asList("test.A", "test.B");
List<String> additionalPlugins = Arrays.asList("test.C");

FakeApplication app = fakeApplication(additionalConfiguration, additionalPlugins, withoutPlugins);
