### Question:
BitstreamFormat { public final void setSupportLevel(int sl) { if ((sl < 0) || (sl > 2)) { throw new IllegalArgumentException("Invalid support level"); } bfRow.setColumn("support_level", sl); } BitstreamFormat(Context context, TableRow row); static BitstreamFormat find(Context context, int id); static BitstreamFormat findByMIMEType(Context context,
            String mimeType); static BitstreamFormat findByShortDescription(Context context,
            String desc); static BitstreamFormat findUnknown(Context context); static BitstreamFormat[] findAll(Context context); static BitstreamFormat[] findNonInternal(Context context); static BitstreamFormat create(Context context); final int getID(); final String getShortDescription(); final void setShortDescription(String s); final String getDescription(); final void setDescription(String s); final String getMIMEType(); final void setMIMEType(String s); final int getSupportLevel(); String getSupportLevelText(); final void setSupportLevel(int sl); final boolean isInternal(); final void setInternal(boolean b); void update(); void delete(); String[] getExtensions(); void setExtensions(String[] exts); static int getSupportLevelID(String slevel); static final int UNKNOWN; static final int KNOWN; static final int SUPPORTED; }### Answer:
@Test(expected=IllegalArgumentException.class) public void testSetSupportLevelInvalidValue() { bf.setSupportLevel(5); fail("Exception should be thrown"); }
@Test(expected=IllegalArgumentException.class) public void testSetSupportLevelNegativeValue() { bf.setSupportLevel(-1); fail("Exception should be thrown"); }
