/** Check "TypeDetection"
 * <p>
 * This test will check the file type detection. This will be done by filling
 * properties of a <code>MediaDescriptor</code>.
 *
 * In the test method <code>checkByURLonly</code> the
 * <code>MediaDescriptor</code> was filled at once with the URL of a test
 * file. At second it was filled with a <code>XInputStream</code> from test
 * file. In both subtests the returned file type must match with an expected
 * type.
 *
 * In the test method <code>checkPreselectedType</code> the
 * <code>MediaDescriptor</code> was filled with the URL of the test file and
 * with the name of a type which should be used. The returned type of the
 * <code>TypeDetection<code> must match with an expected type.
 *
 * In the test method <code>checkPreselectedFilter</code> the
 * <code>MediaDescriptor</code> was filled with the URL of the test file and
 * with the name of a filter which should be used. The returned type of the
 * <code>TypeDetection<code> must match with an expected type.
 *
 * In the test method <code>checkPreselectedDocService</code> the
 * <code>MediaDescriptor</code> was filled with the URL of the test file and
 * with the name of a document service which should be used. The returned type
 * of the <code>TypeDetection<code> must match with an expected type.
 *
 *
 * To get information which test file should support which type, filter and
 * document service, this information was collect from configuration files:
 * <UL>
 * <LI><a href="#TypeDetection.props">TypeDetection.props</a></LI>
 * <LI><a href="#files.csv">files.csv</a></LI>
 * <LI><a href="#preselectedFilter.csv">preselectedFilter.csv</a></LI>
 * <LI><a href="#preselectedType.csv">preselectedType.csv</a></LI>
 * <LI><a href="#serviceName.csv">serviceName.csv</a></LI>
 * </UL>
 * <p>
 * <h3><A name="TypeDetection.props"></A>
 * <code>typeDetection.props</code></h3>
 * At fist there will be the <code>typeDetection.props</code>. Here the following
 * properties should be set (with example values):
 *
 * TestDocumentPath=file:///path/to/my/testdocuments
 * placeHolder=%
 * %SO6productname=StarOffice
 * %SO6formatversion=6.0
 *
 * <code>TestDocumentPath</code>: this is the path to your test documents. If
 * you have grouped your documents ie. by writer, calc, ... then it should be
 * the root path. To specify the particular sub folders you have to use
 * <code>csv.files</code>
 * <p>
 * <code>files.csv</code>: In this file all test documents are listed.
 * Syntax: fileAlias;fileURL;defaultURLFileType;StreamFileTypes
 * Example:
 *
 * Writer6_1;Writer/Writer6.sxw;writer_StarOffice_XML_Writer;writer_StarOffice_XML_Writer
 * text1;Writer/Text.txt;writer_Text_encoded:writer_Text;writer_Text_encoded:writer_Text
 *
 * The first example shows you the following:
 * <code>Writer6_1</code> is a free chosen name
 * <code>Writer/Writer6.sxw</code> is the document path. This will be assembled
 * by <code>TestDocumentPath</code> from <code>typeDetection.props</code>.
 * <code>writer_StarOffice_XML_Writer</code>: this is the default file type of
 * this file
 *
 * The second example displays two document types for <code>XInputStream</CODE>
 * (<code>writer_Text_encoded</CODE> and <code>writer_Text</CODE>. This two
 * document types are listed by a colon ':' as separator. This is needed because
 * XInputStream can detect a text file as writer_Text_encoded as well as
 * writer_Text.
 * <p>
 *
 * <H3><A name="preselectedFilter.csv"</a>
 * <code>preselectedFilter.csv</code></H3>
 * In this file you can choose a special
 * filter to detect the document. This make sense ie. for csv-files: You can
 * open csv files as Writer or as Calc. To check this case you have to specify
 * in <code>csv.files</code> a fileAlias like ?csv_writer? and ?csv_calc? with
 * the same fileURL and it's specific defaultFileType.
 * The returned file type by <code>TypeDetection</code> must equal to
 * correspond <code>defaultFileType</code> from <code>csv.files</code>
 *
 * Syntax: fileAlias;FilterName;FilterOptions;FilterData
 * Example: Writer6_1;%SO6productname %SO6formatversion Textdokument;;
 *
 * The example shows the following:
 * <code>Writer6_1</code> is the same as in <code>csv.files</code>
 * <code>%SO6productname %SO6formatversion Textdokument</code> is the filter
 * name which should be used. Here we have a special: <code>%SO6productname
 * %SO6formatversion</code> will be replaced by the equals of
 * <code>typeDetection.props</code>. The filter names depends on the Office
 * name and version. So a future Office could called ?StarSuite 8?.
 * <code>FilterOptions</code> is not relevant for this filter. But ie. for csv
 * filter this entry could be used to specify the separator of the csv file.
 * <code>FilterData<code> if filter needs some FilterData arguments you can
 * specify it here
 *
 * <p>
 * <H3><a name="preselectedType.csv"></A>
 * <code>preselectedType.csv</code></H3>
 * In this file you can preselect the type
 * <code>TypeDetection</code> should use.
 * The returned file type by <code>TypeDetection</code> must equal to the
 * preselected file type.
 * Note: If you try to use invalid types you will get a failed test because
 * <code>TypeDetection</code> tries to find out the type itself.
 *
 * Syntax: fileAlias;fileType
 * Example: Writer6_1;writer_StarOffice_XML_Writer
 *
 * This example shows the following:
 * <code>Writer6_1</code> is the same as in <code>csv.files</code>
 * <code>writer_StarOffice_XML_Writer</code> is the file type which was used as
 * parameter in <code>MediaDescriptor</code>. This type must be returned from
 * <code>TypeDetection</code>
 *
 * <p>
 * <H3><a name="serviceName.csv"></A>
 * <code>serviceName.csv</code></H3> In this file you can preselect a service name
 * to detect the file type. The returned file type by
 * <code>TypeDetection</code> must equal to correspond
 * <code>defaultFileType</code> from <code>csv.files</code>
 *
 * Syntax: fileAlias;serviceName
 * Example: Writer6_1;com.sun.star.text.FormatDetector
 *
 * This example shows the following:
 * <code>Writer6_1</code> is the same as in <code>csv.files</code>
 * <code>com.sun.star.text.FormatDetector</code> is the service name which was
 * used as parameter in <code>MediaDescriptor</code>.
 *
 *
 * <p>
 * All these files will be copied by make file beside of
 * <code>typeDetection.class</code>.
