> When testing error handling in code that uses streams one needs a way to
> simulate an IOException being thrown by a stream. Typically this means using
> a custom stream class that throws the desired exception. To avoid having to
> implement such custom classes over and over again for multiple projects, I'd
> like to introduce such classes in Commons IO.
> The proposed BrokenInputStream and BrokenOutputStream always throw a given
> IOException from all InputStream and OutputStream methods that declare such
> exceptions.
> For example, the following fictional test code:
> {code}
> Result result = processStream(new InputStream() {
> public int read() throws IOException {
> throw new IOException("test");
> }
> });
> assertEquals(PROCESSING_FAILED, result);
> {code}
> could be replaced with:
> {code}
> Result result = processStream(new BrokenInputStream());
> assertEquals(PROCESSING_FAILED, result);
> {code}
