UploadElement

Full API (methods, signatures, descriptions): see api-reference.md. This note covers only behaviour that isn't obvious from the signatures.

Files are fed through the hidden native file input

uploadFiles(Path...) feeds files via the component's hidden native <input type="file"> (Playwright setInputFiles), not by clicking the upload button. Upload completion is asserted from the file row's state, so wait for it after adding a file rather than assuming the upload is instant.

Path testFile = Path.of("/path/to/test.pdf");
upload.uploadFiles(testFile);

upload.assertHasFile("test.pdf");
// Wait for the row to report completion
upload.assertFileComplete("test.pdf");
