Adding assertions to TestRequest dynamically using Groovy

Hi,
I have an urgent requirement in my project which needs to be implemented.
The requirement is that all the Input XML and the XPath assertions will be moved to the database.
The project file will not have the input XML or assertions in the Test Request.
To execute this we have created the following steps.
1. Datasource step to read the request_xml and assertion_text from DB
select request_xml, test_case_name, request_id, assert_text
from TEST_REQUEST_DATA A, ASSERTIONS_DATA B
where A.REQUEST_ID = B.ASSERT_REQUEST_ID

2. Property Transfer step to feed the request_xml property from the DataSource to the TestRequest Step.

3. Groovy Script to add assertions to the Test Request by getting the assertion_text from the DataSource

def assertText = testRunner.getTestCase().getTestStepByName("DataSource").getPropertyValue("assert_text")
testRunner.getTestCase().getTestStepByName("Test Request").addAssertion(assertText)

Step 3 fails giving the following exception

My question is:
Is it possible to dynamically add assertions to a TestRequest?
And if it is could you please point out where I am going wrong.
Would appreacite any help with this problem.
Best Regards

Hi,

try the following:

def assertion = testRunner.getTestCase().getTestStepByName("Test Request").addAssertion("XPath Match")
assertion.path = ...
assertion.expectedContent = ...

Hope this helps,

Thanks a lot for the code snippet that was what i was looking for. Using the following script I was able to achieve what i was trying to do.

def assertionsList = testRunner.getTestCase().getTestStepByName("Test Request").getAssertionList()
for( e in assertionsList){
testRunner.getTestCase().getTestStepByName("Test Request").removeAssertion(e)
}

def testCaseName = testRunner.getTestCase().getTestStepByName("DataSource").getPropertyValue("test_case_name")
def assertText = testRunner.getTestCase().getTestStepByName("DataSource").getPropertyValue("assert_text")
def assertion = testRunner.getTestCase().getTestStepByName("Test Request").addAssertion("XPath Match")

println " \n\n ########## Start TestCase Name " + testCaseName
assertion.name = testCaseName
assertion.path = assertText
assertion.expectedContent = true

Thanks once again

Hi,

this is definitely possible. The value of the assertText argument in your script must match that of one of the available assertion types as displayed in the combo box when adding a new assertion via the GUI.. what value are you specifying?

Hi Ole,
I am trying to add XPath Match assertion. The api for addAssertion does not take any assertionType parameter, all it takes is a String which I am assuming is the XPath eg:
declare namespace ns1='http://nextel.com/ovm';
//ns1:ovm/ns1:ovm-response/ns1:plans-response/ns1:price-plan/ns1:plan-id = 'FF1001H'

Hi!

this is really cool actually (ie loading requests/assertions from a database), maybe something that should be supported natively?

regards!

Hi!

sure, just get hold of the assertion and set its name property;

testCase.testRunner.testSteps["Request 1"].getAssertionByName( "My XPath Match" ).name = "..."

regards!

Hi Ole,
Thanks a lot.it's working ...I have another doubt...How to declare namespaces in the XPATH-match assertion using groovy script???

Hi!

use the XmlUtils.declareXPathNamespaces( String xmlString ) method, which will return the namespace declarations for all namespaces used in the specified xml string.

Hi:

Talking about removing/adding/renaming Assertions, you posted before that to remove assertions we can use:
def assertionsList = testRunner.getTestCase().getTestStepByName("Test Request").getAssertionList()
for( e in assertionsList){
testRunner.getTestCase().getTestStepByName("Test Request").removeAssertion(e)
}

Is there any way we can remove the assertion by assertion type and/or assertion name? Ex: Remove all type "XPath Match", or with name "My XPath Match"?

Thanks.
