java.lang.Object
- com.sun.javatest.finder.BinaryTestWriter

```
public class BinaryTestWriter
extends java.lang.Object
```
BinaryTestWriter creates the data file used by BinaryTestFinder. It uses a test finder to find all the tests in a test suite and writes them out in a compact compressed form. By default it uses the standard tag test finder, and writes the output in a file called testsuite.jtd in the root directory of the test suite.
Options:

-finder finderClass finderArgs ... -end
the test finder to be used to locate the tests; the default is the standard tag test finder
-strictFinder
Do not ignore errors from the source finder, exit with error code instead
-o output-file
specify the name of the output file; the default is testsuite.jtd in the root directory of the test suite.
testsuite
(Required.) The test suite root file.
initial-files
(Optional)Any initial starting points within the test suite: the default is the test suite root

               java.io.IOException
```
Main work method. Reads all the arguments on the command line, makes sure a valid testFinder is available, and then calls methods to create the tree of tests and then write the binary file.

Parameters:

args - An array of strings, typically provided via the command line

Returns:

The disposition of the run, i.e. zero for a problem-free execution, non-zero if there was some sort of problem.

Throws:

BinaryTestWriter.BadArgs - if a problem is found in the arguments provided
