私も数種類のレポートで実行しましたが、テストクラス内で作成したレコードは完全に無視されてしまいます。実際のデータしか読まないですね。

またフィルターを追加したのですが、実際のデータに対しても全く機能しません。

同じような質問を見つけました。

If I manually create an Opportunity in the Org with a Name of 'ApexTestOpp' then the assertion succeeds. The report running in the unit test is not seeing the records created by the unit test.

I tried to report this through Salesforce Support and they said my company would need to upgrade to Premium Support in order for them to even take a look at it, which is completely absurd. This is broken. Salesforce needs to fix it. I'm posting here in the hope that someone from Salesforce sees it and can do something about it.

結論

説明と違って既存のレコードにしか使えないようです。
フィルターの追加も機能しません。

Salesforce Reports and Dashboards API via Apexを使ってみる
