JUnitテストでのエラーについて[NoSuchMethodError]

Question

###前提・実現したいこと

お世話になります
Eclipse Spring Mavenプロジェクトを
JUnitでテストする際にエラーが出ます。

トレースを確認したところ、
「java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.clearCache()V」
というエラーで、使用しているSpring Coreが重複などしているとなるようです。
昨日"Failed to load ApplicationContext"のエラーを解消するために
ビルド・パスのspring-coreを3.2.3から4.1.6に差し替えました。

こちらはpom.xmlの設定などで直せるものでしょうか？
どうぞよろしくお願いいたします。

テスト用ApplicationContext.xmlの公開を求む、

[xxxAIxxx]

ありがとうございます。テスト用ということが分からないのですが、src/main/webapp/WEB-INF/にあるものを追加いたしました。

Answer 1

pom.xmlに

<!-- https://mvnrepository.com/artifact/org.springframework/spring-test -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>4.1.6.RELEASE</version>
    <scope>test</scope>
</dependency>

を追加したらこのエラーが解消されました。
