## com.sun.javatest.lib
Class MultiTest

    java.lang.Object
      com.sun.javatest.lib.MultiTest

All Implemented Interfaces:
  Test

    public class MultiTest

extends java.lang.Object
implements Test

Base class for tests with multiple sub test cases. This base class implements the standard com.sun.javatest.Test features so that you can provide the additional test cases without concern about the boilerplate needed to execute individual test case methods.

You must add individual test case methods to your derived test class to create a useful test class. Each test case method must take no arguments. If you need to pass an argument into a test method, you should design a wrapper test case to calculate the argument values and then call the test method with the correct arguments. The test case methods must implement this interface:

> `public Status methodName( )`

  `Test`, `TestCases`

Nested Class Summary
`static class` | `MultiTest.SetupException` This exception is thrown when a problem occurs initializing the test.

Field Summary
`protected java.io.PrintWriter` | `log` Output to be logged to result file.
`protected java.io.PrintWriter` | `ref` Output to be logged to result file.

Constructor Summary
`MultiTest()`

Method Summary
`protected void` | `decodeAllArgs(java.lang.String[] args)` Parses the arguments passed to the test.
`protected int` | `decodeArg(java.lang.String[] args, int index)` Decode the next argument in the argument array.
`protected void` | `init()` A setup method called after argument decoding is complete, and before the test cases are executed.
`protected Status` | `init(java.lang.String[] args)` Deprecated. Use `decodeArg(String)` and `init()` instead.
`protected Status` | `invokeTestCase(java.lang.reflect.Method m)` Default way to invoke a specified test case.
`Status` | `run(java.lang.String[] argv, java.io.PrintStream log, java.io.PrintStream ref)` Run the test cases contained in this object This method is a convenience wrapper around the primary run method which takes PrintWriters: this variant takes PrintStreams and wraps them into PrintWriters.
`Status` | `run(java.lang.String[] args, java.io.PrintWriter log, java.io.PrintWriter ref)` Run the test cases contained in this object.

Field Detail

### ref

    protected java.io.PrintWriter ref

  Output to be logged to result file.

### log

    protected java.io.PrintWriter log

  Output to be logged to result file.

Constructor Detail

### MultiTest

    public MultiTest()

Method Detail

### run

    public Status run(java.lang.String[] args,
                      java.io.PrintWriter log,
                      java.io.PrintWriter ref)

  Run the test cases contained in this object. The test cases are determined and invoked via reflection. The set of test cases can be specified with -select case1,case2,case3... and/or restricted with -exclude case1,case2,case3...

  Specified by:
    `run` in interface `Test`
  Parameters:
    `args` - Execute arguments passed in from either the command line or the execution harness.
    `log` - Output stream for general messages from the tests.
    `ref` - Output stream for reference output from the tests.
  Returns:
    Overall status of running all of the test cases.
  See Also:
    `decodeAllArgs(java.lang.String[])`, `init(java.lang.String[])`

### run

    public final Status run(java.lang.String[] argv,
                            java.io.PrintStream log,
                            java.io.PrintStream ref)

  Run the test cases contained in this object This method is a convenience wrapper around the primary run method which takes PrintWriters: this variant takes PrintStreams and wraps them into PrintWriters.

  Parameters:
    `argv` - Execute arguments passed in from either the command line or the execution harness.
    `log` - Output stream for general messages from the tests.
    `ref` - Output stream for reference output from the tests.
  Returns:
    Overall status of running all of the test cases.
  See Also:
    `decodeAllArgs(java.lang.String[])`, `init(java.lang.String[])`

### init

    protected Status init(java.lang.String[] args)

  Deprecated. Use `decodeArg(String)` and `init()` instead.

  Initialize the test from the given arguments. The arguments will be passed to `decodeAllArgs`, and then `init()` will be called.

  Parameters:
    `args` - The arguments for the test, passed to `decodeArgs`.
  Returns:
    null if initialization is successful, or a status indicating why initialization was not successful.
  See Also:
    `decodeAllArgs(java.lang.String[])`, `decodeArg(java.lang.String[], int)`, `init()`

### init

    protected void init()
                 throws MultiTest.SetupException

  A setup method called after argument decoding is complete, and before the test cases are executed. By default, it does nothing; it may be overridden to provide additional behavior.

  Throws:
    `MultiTest.SetupException` - if processing should not continue. This may be due to some inconsistency in the arguments, or if it is determined the test should not execute for some reason.

### decodeAllArgs

    protected final void decodeAllArgs(java.lang.String[] args)
                                throws MultiTest.SetupException

  Parses the arguments passed to the test. This method embodies the main loop for all of the test's arguments. It calls `decodeArg` for successive arguments in the argument array.

  Parameters:
    `args` - arguments passed to the test.
  Throws:
    `MultiTest.SetupException` - raised when an invalid parameter is passed, or another error occurred.
  See Also:
    `decodeArg(java.lang.String[], int)`

### decodeArg

    protected int decodeArg(java.lang.String[] args,
                            int index)
                     throws MultiTest.SetupException

  Decode the next argument in the argument array. This will typically be overridden by subtypes that wish to decode additional arguments. If an overriding method does not recognize an argument, it should return `super.decodeArg(args, index)` to give supertypes a change to decode the argument as well.

  Parameters:
    `args` - The array containing all the arguments
    `index` - The position of the next argument to be decoded.
  Returns:
    the number of elements in the array were "consumed" by this call.
  Throws:
    `MultiTest.SetupException` - is there is a problem decoding the argument.

### invokeTestCase

    protected Status invokeTestCase(java.lang.reflect.Method m)
                             throws java.lang.IllegalAccessException,
                                    java.lang.reflect.InvocationTargetException

  Default way to invoke a specified test case.

  Parameters:
    `m` - The method to be invoked.
  Returns:
    The result of invoking the specified test case.
  Throws:
    `java.lang.IllegalAccessException` - if there was a problem accessing the specified method
    `java.lang.reflect.InvocationTargetException` - if the specified method threw an exception when it was invoked.
