Annotation Processor のテスト書きたいなと思って書いてた。
[java] モダンな Annocation Processor の開発手順まとめ - tokuhirom's blog
package com.github.hisaichi5518.konohana.processor; import com.google.common.truth.Truth; import com.google.testing.compile.JavaFileObjects; import com.google.testing.compile.JavaSourceSubjectFactory; import org.junit.Test; public class KonohanaProcessorTest { @Test public void test() { Truth.assert_().about(JavaSourceSubjectFactory.javaSource()) .that(JavaFileObjects.forResource("Success.java")) .processedWith(new KonohanaProcessor()) .compilesWithoutError(); } }
コンパイルが通ったらテストが通るというのをやろうとしたら通らない!!!なぜ!!javapoetのTypeName.get() できてない!

コンパイル対象のファイルを見てたら、java.util.List
がimportされてなかった…マジか………。追加したら無事なおった。
追記:
gfxさんにテストの内容について教えてもらった
正常系はlibrary側でやるのがよさそう
annotation prosessorのテスト、コンパイルエラーにしたいケースでしかやってないです。というか、機能のテストはできないからテストの意味がない…。

正常系は、生成したコードの機能をテストするのがいいんじゃないですかね。
