Check previous test step for the existence of a value

[thatsthat]

Hopefully this is something that is covered off in the existing functionality of Ready API.

I have a value in the results of Test Step B which is the Amount 742.50

<ns2:Rates>
<ns2:RateTotals>
<ns2:BuyTotal>
<ns2:Currency>AUD</ns2:Currency>
<ns2:Amount>742.50</ns2:Amount>
</ns2:BuyTotal>

I simply want to check - or 'Assert' - if the value 742.50 appears in a previous Test Step (i.e. it 'exists' in the previous test step results). I know how to do Existence check (true or false) out of the box but the previous step contains a list of all kinds of amounts like 800.00 and 200.00 and 595.00 etc.

@thatsthat, you can use XPath assertion, see

The issue is @KarelHusa the value can appear in a variety of positions .. there is not just 1 amount returned .. there are many .. so i am looking to match the current result 'anywhere' in the previous step's result.

@thatsthat,

XPath assertions work exactly for such purpose.

An XPath expression like //ns2:BuyTotal/ns2:Amount = 742.50 should work for you.

ReadyAPI will help you declare namespaces and set up the XPath expression; please look at XPath Match docs for more detail.

Thanks for your suggestion @KarelHusa but here is an example of just one of the elements I want to inspect. You can see the [1] in the response .. but there are (in this example I am looking at) 7 entries I need to check to see if a match exists. Xpath (without writing a script) can only point to 1 value .. unless I am mistaken?

${AddService#Response#declare namespace ns2='http://xyz.com/schema'; //ns2:AddServiceResponse[1]/ns2:Response[1]/ns2:ServiceDetail[1]/ns2:TotalCost[1]}

@thatsthat,

you can use XPath predicates in your assertion, such as:

//ns2:BuyTotal/ns2:Amount[text() = 742.50]

will select the XML element amount with a value of 742.50.

You can also check the count of nodes:

count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0

.

XPath gives you multiple options to select the node, see e.g. https://www.w3schools.com/xml/xpath_syntax.asp .

Thanks for your patience @KarelHusa .. I will need to do some more reading it appears (thanks for the URL you sent) .. I attempted to implement your graceful solution with the count .. but no luck:

count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0

But to no avail .. the below is what I am using to match a 'single' amount record that is being returned .. but I can't get it to 'count' up all the records and find if > 0 of them = 742.50

${FastSearchPackage#Response#declare namespace ns2='http://www.xyz.com/gateway/fire/schema'; //ns2:SearchResponse[1]/ns2:Response[1]/ns2:Suppliers[1]/ns2:Supplier[1]/ns2:Products[1]/ns2:Product[1]/ns2:Rates[1]/ns2:RateTotals[1]/ns2:BuyTotal[1]/ns2:Amount[1]}

I get a 1 for 1 match .. i tried adding count blah blah but could not land the correct answer!!

I did also try with an 'Count' xpatj expression

declare namespace ns2='http://www.xyz.com/gateway/fire/schema';
${FastSearchPackage#Response#declare namespace ns2='http://www.xyz.com/gateway/fire/schema'; //ns2:SearchResponse[1]/ns2:Response[1]/ns2:Suppliers[1]/ns2:Supplier[1]/ns2:Products[1]/ns2:Product[1]/ns2:Rates[1]/ns2:RateTotals[1]/count(ns2:BuyTotal[1]/ns2:Amount[text()=742.50])>0}

But no joy.

@thatsthat,

relying on a fixed position (using indexes in your XPath) in XML may be fragile. Next time you may get additional elements, and your XPath will no longer work.

That's where a query helps.

What kind of response do you get if you test the following expressions:

//ns2:BuyTotal/ns2:Amount[text() = 742.50]

count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0

[thatsthat]

The thing is .. this does not point to the test step I need to collect the information from .. so I believe I am not constructing the message correctly .. 

count(//ns2:BuyTotal/ns2:Amount[text() = 742.50]) > 0

So i get:

The XPath Match assertion failed for the following path: [declare namespace ns2='http://www.xyz.com/gateway/fire/schema'; declare namespace env='http://www.w3.org/2003/05/soap-envelope'; //ns2:BuyTotal/ns2:Amount[text() = 742.50]]. Expected value: [394.50]; Actual value: [].
