Annotation Processor のテスト

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
