You can test your StreamBase application by running it, then sending it a set of test data in the exact format expected by your application's input streams. A collection of such test data is called a feed simulation.
Feed simulations have the following characteristics:
-
Feed data can be generated automatically from random data, each field according to its expected data type.
-
You can customize your feed data to contain actual sample data, or realistic data of the exact format expected by your input streams.
-
Your feed data can be formed from a mix of automatically generated and customized data.
-
You can have feed data read from a comma-separated or tab-delimited file.
-
You can ramp up the data rate of your simulated feed to stress-test your application.
-
You can save feed simulations as disk files to be shared among developers or used in different projects.
-
You can edit saved feed simulation files.
You can run feed simulations in several ways:
-
In StreamBase Studio, you can send data manually, one tuple at a time.
-
In Studio and on the command line, you can run a generic feed simulation that generates random data.
-
In Studio and on the command line, you can run a saved feed simulation file.
The following topics provide the details of creating, maintaining, and running feed simulations for StreamBase applications.
