Assert every instance of a json attribute Is UNIQUE
Hey,
It's more of almost the same from me - I apologise...I'm getting boring. I need to assert a repeating json attribute always contains a unique value
nmrao provided the following code to assert if the repeating DataSourceId_Name attribute was null (JSONPATH to DataSourceId_Name= $['data'][0]['DataSourceId_Name']
assert context.response, 'Request parameter is correct'
def json = new groovy.json.JsonSlurper().parseText(context.response)
assert json.data.DataSourceId_Name.every{null == it}
I know need to assert that the repeating attribute value is always unique.
tbh - I thought I'd already asked this a while ago - so apologise if I'm repeating myself - I can't find the post.
I did a bit of googling and found the unique() method - I tried messing around with the following:
assert context.response, 'Request parameter is correct'
def json = new groovy.json.JsonSlurper().parseText(context.response)
assert json.data.DataSourceId_Name.every{unique()== it}
Obviously this isn't working - and I haven't a clue how to fix it.
I also tried the following:
def json = new groovy.json.JsonSlurper().parseText(context.response)
json.data.Name.each {
assert it == it.unique()
}
but I got the following response for this
No signature of method: java.lang.String.unique() is applicable for argument types: () values: [] Possible solutions: minus(java.lang.Object), minus(java.util.regex.Pattern), size(), size(), use([Ljava.lang.Object;), use(java.util.List, groovy.lang.Closure)
Would anyone be able to steer me what I'm doing wrong??
Cheers!

One way I did this, to assert uniqueness across multiple paginated replies is to make use of a properties step. This way, as I assume you will page through the request multiple times, you can keep an accurate count of how many times a value appears.I had to do this to ensure we were paginating through every object in the cache, and had to keep a running total of how many times any one unique identifier came back. I had 20,000 objects and could only pull 200 at a time, so I kept a running properties step that contained the unique ID and how many times it appeared. If pagination worked as expected, I ended up with 20,000 objects with each having a count of 1. Should be similar to what you are trying.
Something similar to this hastily written psuedo code:
// Set up a property step to contain our property names and counts. def propertiesStep = context.testCase.testSteps["NameCount"] // get the list of DataSourceId_Name values on current page of values DataSourceId_Name= $['data']['DataSourceId_Name'] // Loop through the idNames for idName in DataSourecId_Name { // get the property value from the properties step above. def propertyValue = propertiesStep.getPropertyValue(idName); // if the property has a value, increment it by 1 if (propertyValue != null) { propertiesStep.setPropertyValue(idName, (propertyValue.toInteger() + 1).toString()); } // if the property does not exist, assign it a count of 1 else { propertiesStep.setPropertyValue(idName, "1"); } }richie ,
There is no need to create properties step.
Just verify with in Groovy script itself.
def response = context.expand( '${REST Request#Response}' ) def json = new groovy.json.JsonSlurper().parseText(response) def totalNamesCount = json.data.TransporterId_Name.size() //Below removes the duplicates and does the count def uniqueNamesCount = json.data.TransporterId_Name.unique().size() // If you want find which name and number of times it occurs, uncomment below block of code /* def list = json.data.TransporterId_Name.unique() list.each { element -> log.info "$element : ${json.data.TransporterId_Name.findAll { it == element}.size()}" } */ //Since you wanted all the names are unique, both the counts should be same assert totalNamesCount == uniqueNamesCount, 'There are duplicate Transporter Names'Please see the above if you want to check the same?
