`@SpringBootTest` properties on class BookmarkControllerTest; change the
annotation so the datasource URL uses the JVM temp dir placeholder instead (e.g.
jdbc:sqlite:${java.io.tmpdir}/bookmark-controller-test.db) so it becomes

Spring Boot @SpringBootTest properties attribute system property placeholder resolution java.io.tmpdir
💡 Result:
In Spring Boot tests, property placeholders (such as ${java.io.tmpdir}) used within the properties attribute of @SpringBootTest (or @TestPropertySource) are resolved against the Spring Environment [1][2]. Key details regarding this mechanism include: 1. Environment Resolution: When you define inlined properties using the properties attribute, these key-value pairs are added to the Spring Environment as a test PropertySource [1][3]. Spring's PropertySourcesPropertyResolver is responsible for resolving placeholders like ${java.io.tmpdir} by looking up the corresponding value in the aggregated Environment [4]. 2. Precedence: Properties defined via the properties attribute of @SpringBootTest or @TestPropertySource have higher precedence than those loaded from application properties files or standard system properties [1][3]. This allows you to selectively override values during testing [1]. 3. Common Pitfalls: - Build Tool Interference: If you are using build tools like Maven or Gradle with resource filtering enabled, placeholders using the ${...} syntax may be expanded by the build tool before they ever reach the Spring Framework [5][6]. To prevent this and allow Spring to resolve them at runtime, you may need to escape the placeholder (e.g., ${java.io.tmpdir}) [5][7]. - Unresolved Placeholders: If a placeholder cannot be resolved (e.g., the key is missing or mistyped), Spring will typically throw an IllegalArgumentException: Could not resolve placeholder [8]. Ensure the property key is correctly defined in the environment or as a system property accessible to the test context [9][8]. For complex scenarios where you need to resolve properties dynamically based on other beans or environment state, consider using @DynamicPropertySource, which offers more flexibility and higher precedence than @TestPropertySource or the properties attribute [1][3].

テストDBパスの /private/tmp ハードコードを環境非依存に修正してください。（BookmarkControllerTest 20行目）
@SpringBootTest(properties=...) が jdbc:sqlite:/private/tmp/bookmark-controller-test.db を直接指定しており、Linux等ではディレクトリが存在せずテスト失敗につながり得ます。/private/tmp を ${java.io.tmpdir} に置き換えるのが安全です（build.gradle に resource filtering 等のビルド時展開設定は見当たりません）。
