Class Regress

java.lang.Object

org.xhtmlrenderer.test.Regress

public class Regress
extends Object

Creates a directory containing output from the renderer as text, given a set of input files (XHTML, XML). These files serve as the reference image for a comparison with later runs of the renderer. For any input file _input_, the zip will contain _input_, _input.layout.txt_, _input.rendered.txt_ and _input.png_. To use, create an instance of Regress with input directory, output directory and width, then call snapshot().

 Regress regress = new Regress(sourceDir, outputDir, width);
 regress.snapshot();
 

One the regress is done, you can use Zipper to pack it up:

  new Zipper(outputDir, outputZip).zipDirectory();
 

Regress will try to render all files in the source directory; a failure to render one file (e.g. if an exception is thrown) will not stop the rendering process.

Files in the source directory with the following extensions are included: htm, html, xht, xhtml, and xml.

You can also run this from the command line, passing in the source directory as argument 1, and the output file name as argument 2. The output is created in the standard temp directory in a subdirectory called "reference". The path to the output directory will be printed to the console when complete.

Constructor Detail

Regress

public Regress(File sourceDir,
               File outputDir,
               int width)

Initialize to read from sourceDir and generate files to outputDir, using width points to constrain layout.

Parameters:

sourceDir - directory to read from

outputDir - directory to write to

width - width to constrain layou to

Method Detail

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception

snapshot

public void snapshot()
              throws IOException

For all files in the input directory, attempts to render and output a textual box model and a PNG file in the output directory. Does not zip the contents of the output directory. Any single file that fails to render will not halt the process. Low-level IO errors will may, however, interrupt it. Both the file count and the failed count are reset on starting; on finishing those values can be read through their respective accessors in this class.

Throws:

IOException - on reading contents or writing output
