我正在学习关于Android的测试，但是在使用Dagger Hilt进行测试时，遇到了以下错误：
> Task :app:kaptDebugAndroidTestKotlin
C:\Users\Henrique\Dev\Projetos-Android\TestingOnAndroidTutorial\app\build\generated\source\kapt\debugAndroidTest\com\youtube\tutorials\testingonandroidtutorial\di\TestAppModule_ProvideInMemoryDbFactory.java:11: error: cannot find symbol

当运行测试并且发生在Android生成的类中时，会导致此错误，但我不知道如何解决它。我已经在互联网上查找，但没有找到有关此错误的任何信息。
以下是我的Dao和测试模块：
