🕵️ Lint checks

• AssertionsDetector

  • Prefer using kotlin.test assertions instead of JUnit's in Kotlin unit tests.
  • Prefer using kotlin.test assertions instead of assert in unit tests. Its execution requires a specific JVM option to be enabled on the JVM.

• GradleVersionCatalogDetector

  • Dependencies should be sorted alphabetically to maintain consistency and readability.
  • Dependencies should follow the configured regex.
  • Extracting a version in the [versions] section is useful only if it is used more than once or referenced elsewhere.
  • Dependency declaration should use the simplest form possible, omitting unnecessary inline tables.

• NamedParametersDetector

  • Not specifying parameters name using the same type can lead to unexpected results when refactoring methods signature.
    Enforcing explicit named parameters also helps detecting mistakes during code review.
    Quick fix: ⌥⏎ (macOS) or Alt+Enter (Windows/Linux) ➝ Add names to call arguments.

• ReplaceMethodCallDetector

  • The method foo() should not be called!

• TestMethodBannedWordsDetector

  • Test methods name should not contains banned words. The default behavior checks for failure,failed words to reduce collisions when searching through logs.

• TypographyDetector

  • Escaped character are impossible to decipher for a human. Using unescaped character is generally self explanatory.
  • Typography can be replaced with a better alternative.
  • Curly quotes must be replaced with straight quote as Talkback does not properly handle them.
