I am writing test cases in TypeScript, and Codacy/ESLint flags an error when I use require() statements to import modules inside my tests. The linter suggests replacing require() with ES6-style import statements for better type checking and consistency.
However, since import statements must be at the top of the file, when I move these imports there and call them inside individual test cases, I encounter multiple errors. After fixing those errors, I notice that the code coverage contributed by those test cases drops significantly compared to when I used require() dynamically.
How can I resolve these issues?
- Is there a recommended way to dynamically import modules in TypeScript tests to avoid lint errors and preserve coverage?
- Can I use dynamic import() in tests, or should I selectively disable ESLint rules for require in test files?
- What are the best practices for structuring imports in TypeScript Jest tests to maintain good type safety and accurate coverage?
