JUnitによるAssertion errorの原因がわからない

Question

現在、JUnitでテストを行っているのですが、エラーが解決できない状況です。

エラー文から判断すると、期待されている内容と値が違うと考えられるのですが、データを確認してみるとデータがあっているはずなのですがエラーが出てしまいます。

わかる方がいれば、エラーの原因をご教授ください。よろしくお願いします。

Answer 1

DeploymentEntity@6eb…という型が返ってきてほしいのに対してDeploymentEntity@1…という型が返ってきているため、クラスの型が不一致というエラーになっています。
（List<DeploymentEntity@6eb...>とList<DeploymentEntity@1...>を比較して型が違うのでアンマッチ）

DeploymentEntity@6eb…とかDeploymentEntity@1…はSpringがDeploymentEntityを元に動的に生成したクラスです。

"deploymentData"とlist、そのものを比較するのではなく、面倒でもlistの中に入っているEntityのそれぞれの中身（あるいは1件目だけを取り出すとか）を比較するほうがいいです。

listの中にある中身をassertThatで比較することで解決しました。
ありがとうございます！
