### What does this PR do?

This PR updates a test assertion to match the actual exception message being thrown in the code.

The test was previously expecting the message:
`<failingType> endpoint needs to be provided without http(s)://.`

But the actual exception thrown is:
`<failingType> endpoint needs to be provided without "http(s)://".`

The discrepancy caused the test to fail. This fix ensures the test correctly reflects the expected output, including the necessary double quotes.

### Changes made

- Updated `$this->expectExceptionMessage(...)` to include the quoted string `"http(s)://"`.

No other logic or behavior has been changed.

  The exception is thrown with `"http(s)://"` in quotes.

  The test incorrectly expects the message without quotes.
