The link to the test file was broken

[Issei0804-ie]

The extension of the test file is .ts, but the documentation states a .js extension, which prevents navigation to the test file.

As a result, clicking on the TestSource in the image below does not lead to the test file.

In this PR, I have changed the extension of the test file mentioned in the documentation to .ts.
