Data correlation is reusing values returned by a tested web server in subsequent requests in load tests. You use data correlation when testing web servers that send dynamic data to clients. This way you can make sure that the load test runs successfully.
This section explains how to capture dynamic values generated by the tested web servers and replace hard-coded values in your recorded scenarios with those dynamic values.
In This Section
Explains what data correlation is and when you need to use it.
Describes how LoadComplete correlates simulated request data automatically.
Describes how to command LoadComplete to correlate dynamic parameters in recorded scenarios automatically.
Describes how LoadComplete correlates dynamic parameters, for which data correlation rules are not defined.
Describes how to create custom correlation rules that LoadComplete will use to correlate dynamic parameters automatically.
Describes how to correlate dynamic parameters automatically via the Correlate Request and Response Parameters wizard.
Describes how to correlate dynamic parameters manually.
Describes how the Scenario editor depicts data correlation between requests and responses in scenarios.
Explains why you need to decode or encode extracted data and describes how to define conversion rules.
Explains how you can modify extracted data before you use it in subsequent requests.
