***** QPA FILE FORMAT ******

Date: 21st March 2013

The QPA file is a combination of two formats:
- Container format is the outer format that runs through test
  executable life time
- Per case XML-based log is stored for each test case within
  the container format

The best additional reference is the code used to handle the logs as
well as sample .qpa file. See framework/qphelper/qpTestLog.c, for
example. Also, executor/xeTestLogParser.cpp will be a helful.

The descriptions below flow in the order the items appear in normal
log files. Comments are prefixed with an asterisk ('*').

=== Container format ===

* Container format starts with multiple entries of form:

#sessionInfo [key] [value]

* The session info entries do not have fixed order.
* Info header keys written by a test binary are listed below.
releaseName
releaseId
targetName

* Candy writes and reads the following additional keys:
candyTargetName
resultName
timestamp
configName

* Additional header values will be added as needed.

* The test binary starts actual execution by outputting:
#beginSession

* Each test case looks like:
#beginTestCaseResult <name of the test case>
<Test Case Log - see the separate section below>
#endTestCaseResult or #terminateTestCaseResult <cause>

* Execution done
#endSession


=== Test Case Log ===

* XML log can be incomplete due to, e.g., crash. Please, use a SAX
  parser as they can work with incomplete XML.

* First start the XML stream and open the TestCaseResult element. All
  other elements go into the TestCaseResult element.

<?xml version="1.0"?>

<TestCaseResult Version="0.3.2" CasePath="[path]" CaseType="[type]">
[path] = Full name of the test case. Groups separated with periods ('.')
[type] = SelfValidate,Performance,Accuracy,Capability
The version will be increased any time changes to the format are made.

* After this point there'll be a mix of following elements. Order
  corresponds to the execution of the test case.  All of the elements
  below may contain attributes Name and Description, which will have
  appropriate strings as values. Not all elements will have Name and
  Description.

InfoLogs are the outputs from the GLES log query functions.

* If the test finishes so that the framework has control, the Result
  element is inserted.

 <Result StatusCode="[status]">[Details string]</Result>
[status] =
		Pass,					// Test case passed.
		Fail,					// Test case failed (not passed).
		QualityWarning,			// Result within specification, but suspicious quality wise
		CompatibilityWarning,	// Result within specification, but likely to cause fragmentation
		NotSupported,			// Some feature was not supported in the implementation.
		ResourceError,			// A resource error has occurred.
		InternalError,			// An internal error has occurred.
[Details string] = Further details or measured value as float for Performance and Accuracy cases.

* We are done, let's close the TestCaseResult element
