Choose a data extraction method


Dynamic parameters are link or form parameters that are generated by the server. Normally invisible to the end-user, these parameters are inserted into submitted links and forms.

Unless the test designer decides otherwise, during the test run the recorded values are submitted "as is". Therefore, these values need to be re-worked using a process of data extraction and re-insertion. The Search for dynamic parameters function, included in the Post-recording Wizard, allows you to identify the dynamic parameters and automatically configures the User Path to allow the extraction and insertion of the appropriate data.

The Search for dynamic parameters function automatically handles dynamic parameters in the vast majority of cases. For more complex cases, the parameter must be managed manually using one of the extraction methods described hereinafter.

Extraction methods

NeoLoad provides various data extraction methods to extract and insert link or form parameters. The methods are used automatically by the Search for dynamic parameters function and can be used explicitly for manual extraction.

The following section briefly outlines each method and provides guidance on choosing the appropriate method for each particular case.

Framework parameters

Thanks to its Search for generic dynamic parameters function, NeoLoad can detect and automatically configure dynamic parameters.

The Search for generic dynamic parameters section allows you to automatically detect an application custom dynamic parameters without having to declare them in advance. When this detection fails, the parameter needs to be handled using a variable extractor. NeoLoad allows you to add this Variable Extractor to a list of pre-defined rules so that the search for Framework dynamic parameters automatically handles this custom parameter at each new recording.
