Testing Plugins or Mods

注釈

The changes made by your PR determines whether you need to provide a testing plugin or a testing mod. Any changes to the API require a testing plugin, and any changes to implementation need a testing mod. Test plugin will refer to both for the remainder of this article.

Testing is an integral part of any software development project. Supplying a test plugin accomplishes two goals:

1. Testing

   A test plugin demonstrates you have tested your changes, but it also provides others with the ability to check the current changes as well as future changes.

2. 資料

   A well-commented test plugin provides details not necessarily required in PR documentation. Furthermore, comments in a PR generally last until the PR is merged. Comments in a program last as long as the code remains. They should not provide all of the documentation. Instead, well-commented code supports and completes the documentation.

ちなみに

A good understanding of プラグインの作成 provides a solid foundation for writing test plugins. Plugin requirements apply to test plugins, such as プラグイン ID and ロギングとデバッグ.

You should provide a test plugin when you are contributing new or modified feature(s) to the API or implementation. The plugin is simply a class added to the package org.spongepowered.test, which is found in the SpongeCommon/testplugins/src/main/java/org/spongepowered/test/ directory. The PR for the contributions should include the test plugin.

It is essential that test plugins do not change the game when not intended. As a result, a command should toggle the plugin functionality. Be sure not to confuse this with excluding the test plugins in the build process. A setting in SpongeCommon/gradle/implementation.gradle can exclude test plugins from the resulting jar file. However, a command must toggle the functionality of the test plugin whether or not test plugins get included in a jar file or not.

@Plugin will automatically register your plugin with Sponge, but it will not allow it to be toggled.

The following code demonstrates registering your plugin and allowing it to be toggled:

private boolean registered = false;

@Listener
public void onInit(GameInitializationEvent event) {
    Sponge.getCommandManager().register(this,
        CommandSpec.builder().executor((source, context) -> {
            if (this.registered) {
                this.registered = false;
                Sponge.getEventManager().unregisterListeners(this.listener);
            } else {
                this.registered = true;
                Sponge.getEventManager().registerListeners(this, this.listener);
            }
            return CommandResult.success();
        }).build(), "flowerPotTest");
}

JUnit is used on a limited basis and primarily for internal purposes. Generally speaking, JUnit is useful for testing without a player. However, the best practice is not to use JUnit unless you have agreement from a Sponge staff member.
