addAssertion() not recognizing string value of "Contains" type - groovy

Question

I have a groovy script that I've added code to to check if a value exists in an XML response I'm getting within SoapUI. I've been dealing with this for a few days and could use some help.
Here is the code:
import com.eviware.soapui.support.XmlHolder
import com.eviware.soapui.impl.wsdl.teststeps.registry.RestRequestStepFactory
// read your request template
def requestFile = new File("C:/XMLRequestScript/file.xml");
// parse it as xml
def requestXml = new XmlHolder(requestFile.text)
// get the current testCase to add testSteps later
def tc = testRunner.testCase;
// get the testStep as template to create the other requests
def tsTemplate = tc.getTestStepByName("Template");
// loop to create # of testSteps for each application
for(int i = 1; i < 3; i++) {
// xpath expression to get applicationNumber attribute in root node
def xpathNodeAttr = "/*/#ApplicationNumber";
// get the root node attribute applicationNumber throught an XPATH
int appId = Integer.parseInt(requestXml.getNodeValue(xpathNodeAttr));
// add 1 to appId
appId++;
// set the value again in the attribute
requestXml.setNodeValue(xpathNodeAttr,appId);
// create next testStepName for new Application
def testStepName = "TestStep_ApplicationNumber_" + String.valueOf(appId)
log.info testStepName;
log.info testStepName.getClass().getName()
log.info tc.getClass().getName()
// create a new testStepConfig
def testStepFactory = new RestRequestStepFactory();
def testStepConfig = testStepFactory.createConfig( tsTemplate.getTestRequest(), testStepName )
// add the new testStep to TestCase
def newTestStep = tc.insertTestStep( testStepConfig, -1 )
// set the request
newTestStep.getTestRequest().setRequestContent(requestXml.getXml())
// add Assertions here
def assertion = tc.getTestStepByName(newTestStep.toString()).addAssertion("Contains")
if (assertion.contains("Champion5")) {
newTestStep.addAssertion("Champion5")
log.info("REST response assertion created into: " + newTestStep)
} else {
log.info("REST response assertion not found in " + newTestStep)
}
if (assertion.contains("Challenger5")) {
newTestStep.addAssertion("Challenger5")
log.info("REST response assertion created into: " + newTestStep)
} else {
log.info("REST response assertion not found in " + newTestStep)
}
// execute the request
newTestStep.run(testRunner, context)
}
In the section above called "// add Assertions here", the line of code that I'm having a problem with is:
def assertion = tc.getTestStepByName(newTestStep.toString()).addAssertion("Contains")
The error states:
Thu Sep 18 14:27:57 CDT 2014:ERROR:An error occurred [Cannot invoke method addAssertion() on null object], see error log for details
My understanding is that I have to pass an Assertion Type that is contained in the SoapUI GUI and just put it in as a string value in order to check if the values that I'm checking are asserted.
Any suggestions/direction would be appreciated. I have no idea what I'm doing wrong. Thanks.

Answer 1

I think the problem is your are calling the function tc.getTestStepByName(String name) with a wrong name, because the newTestStep.toString() doesn't return the Test step name instead it returns the class name (it really returns 'classname' + '#' + 'Integer.toHexString(hashCode())' if it's not override it, see Object.toString()) .
Anyway what you want is to add an assertion for a test step which is just created so add the assertion directly to it instead to find it by name, use:
def assertion = newTestStep.addAssertion("Contains")
instead of:
def assertion = tc.getTestStepByName(newTestStep.toString()).addAssertion("Contains")
The second problem you have is that you're using the assertion incorrectly. The assertion object in your case is an instance of SimpleContainsAssertion and contains() method doesn't exist in this class, to set the string to check in contains assert use setToken() method, I think that you need this to add the two assertions:
def assertion = newTestStep.addAssertion("Contains")
// add token to check
assertion.setToken("Champion5")
// change assert name in order to avoid the popup
// when we create the second one.
assertion.setName("CONTAINS 1")
// create a second assertion
assertion = newTestStep.addAssertion("Contains")
assertion.setToken("Challenger5")
assertion.setName("CONTAINS 2")
instead of :
// add Assertions here
def assertion = tc.getTestStepByName(newTestStep.toString()).addAssertion("Contains")
if (assertion.contains("Champion5")) {
newTestStep.addAssertion("Champion5")
log.info("REST response assertion created into: " + newTestStep)
} else {
log.info("REST response assertion not found in " + newTestStep)
}
if (assertion.contains("Challenger5")) {
newTestStep.addAssertion("Challenger5")
log.info("REST response assertion created into: " + newTestStep)
} else {
log.info("REST response assertion not found in " + newTestStep)
}
This code will result creating this two asserts, one named "CONTAINS 1" and check that response contains the string "Champion5", and a second one named "CONTAINS 2" and check that response contains the string "Challenge5".
Hope this helps,
