💻 Code

// src/index.ts
function foo() { return 'bar'; }
// test/index.ts
function foo() { return 'bar'; }
// tsconfig.json
{"compilerOptions": {"outDir": "./dist", "rootDirs": ["./src", "./test"]}}

🙁 Actual behavior

Running tsc with both src/index.ts and test/index.ts outputs 2 files: dist/src/index.js and dist/test/index.js.

BUT running the same command without test/index.ts outputs 1 file: dist/index.js, here the src directory is missing.

🙂 Expected behavior

running the same command without test/index.ts should output 1 file: dist/src/index.js, (with the srcdirectory).
