forward also case- and step results

[simonmeggle]

Send the results optionally also on a case/step basis. Change proposals:

class TestCase old usage:

var testCase = new TestCase(20,30[, path]);

new usage:

var testCase = new TestCase(["custom-caseId", 20,30, "optional-image-path"]);
TestCase.addImagePaths(path);

• the first parameter can overwrite the case id derived from the case folder name
• parameter 2 and 3 specify the warning/critical threshold
• parameter path will be deprecated => use TestCase.addImagePaths(imagePaths) instead to overwrite the default image search path

method endOfStep old usage:

TestCase.endOfStep("foo", 10);

new usage:

TestCase.endOfStep("foo", 10,[ 20, true]);

• add a critical threshold parameter (keep compatibility to warning-only definitions!)
• add a forward flag which sends the step result to forwarder. For monitoring forwarders the following object names are used: hostname: (taken from forwarder definition) _servicedescription: ${testsuite.id}_${testcase.id}_${teststep.id}

method saveResult() old usage:

testCase.saveResult();

new usage:

TestCase.saveResult(true)

• add a forward flag which sends the case result to forwarder. The case execution will stop afterwards. For monitoring forwarders the following object names are used: hostname: (taken from forwarder definition) _servicedescription: ${testsuite.id}_${testcase.id} (as defined by case folder name or TestCase object initialization, see above)

:warning: General note: Rhino script currently DON'T support named parameter like ES2015 Script does. Something like testCase.endOfStep({stepName: "Calculation", optForward: true}); is not possible :cry:

[toschneck]

Change internal forwarder implementation:

• Implement after #310
• Be able to generate data separately for:
  • TestSuite TeardownServiceHelper.invokeTeardownServices
  • TestCase
  • TestStep
• For services which don't support the new modes throw Exception "not supported"
