        assertEquals(MediaType.application("x-tika-ooxml"), detector.detect(xlsx, m));
    }
    // With truncated data + filename, we can use the filename to specialise
    m = new Metadata();
    m.add(Metadata.RESOURCE_NAME_KEY, "testEXCEL.xlsx");
    try (TikaInputStream xlsx = getTruncatedFile("testEXCEL.xlsx", 300)) {
        assertEquals(MediaType.application("vnd.openxmlformats-officedocument.spreadsheetml.sheet"), detector.detect(xlsx, m));

    // Now a truncated OLE2 file 
    m = new Metadata();
    try (TikaInputStream xls = getTruncatedFile("testEXCEL.xls", 400)) {
        assertEquals(MediaType.application("x-tika-msoffice"), detector.detect(xls, m));
    }
    // Finally a truncated OLE2 file, with a filename available
    m = new Metadata();
    m.add(Metadata.RESOURCE_NAME_KEY, "testEXCEL.xls");
    try (TikaInputStream xls = getTruncatedFile("testEXCEL.xls", 400)) {
        assertEquals(MediaType.application("vnd.ms-excel"), detector.detect(xls, m));
    }
}
