[P1] Guard unit tests against Android Color dependency Running `CodeHighlighter.applyJavaTheme(codeView)` in a local unit test invokes `android.graphics.Color.parseColor`, but the project’s test configuration only includes plain JUnit/Mockito and no Robolectric or Android runtime stubs. When `./gradlew test` executes, this call will throw `RuntimeException: Method parseColor in android.graphics.Color not mocked` before any assertions run (same for `applyXmlTheme` later in the file), causing the entire test task to fail. Consider moving these tests under `androidTest`, adding Robolectric, or mocking the color parsing so the tests can execute in a JVM environment. Useful? React with 👍 / 👎.
