1. Navigate to the URL - http://localhost:3000/temp
2. Go to the file upload section of the application
3. Click on "Choose File" to select a file
4. Select the ORCA log file as the input from the test data folder
5. Observe the text next to the "Choose File" button

Screenshots

Acceptance Criteria

1. When a file is selected, the 'No file chosen' message is immediately replaced with the name of the selected file.
2. Once the file is uploaded successfully, the filename should be displayed under 'Uploaded Files:' and the 'No file chosen' message should be displayed next to 'Choose File'
3. The correct filename should be displayed regardless of the file type or the length of the filename.
4. This behavior should be consistent across different browsers (Chrome, Firefox, Safari, Edge).
5. Add/update the unit test cases accordingly
