Question

I’m testing a web application that usually sends some fairly large XML structures to the app’s web services when communicating back to the web server. Of course, I need to vary the test data – replacing some elements with data from a data source – for each iteration of the test run. Is there a syntax for putting tokens into the recorded XML parameters so that the web performance test will replace the data from a database, another data source, or a Context Parameter during test runs?

Answer 1

This is very simple to accomplish, using double curly brackets around the data source name as in the following example:

<Message>
{{DataSource.TableName.ColumnName}}
</Message>

You can use a context parameter in the parameter as follows:

<Message>
{{ContextParameterName}}
</Message>

This also works with non-XML form post parameters.
