Class TestResult

java.lang.Object
  extended by com.sun.javatest.TestResult

public class TestResult
extends java.lang.Object

The TestResult object encapsulates the results from a test. Test results are formatted in sections of command output, comments and sometimes "streams" of output (stdout for example). Each of these sections is represented by a (@link TestResult.Section Section). Instances of this class are mutable until the result of the section is set or until the result of the test itself is set. Test results are stored in a structured text files. The TestResult class serves as the API for accessing the various components that make up the result of running a test. The status is cached as its size is small and it is accessed often. This class and inner classes will throw IllegalStateExceptions if an attempt is made to modify the any part of the object that has been marked immutable.
