API Simulator 0.9.0 Release

March 23, 2018


The v0.9.0 release introduces enhancements and additions to the YAML DSL (domain-specific language) for configuring simulation simlets for the Standalone API Simulator:

  • CSV (comma-separated values) data as source for parameter values. The CSV data can come from files or be embedded in the simlet’s configuration.
  • SQL data store (RDBMS) as source for parameter values.
  • Lists as source for parameters. The parameter’s value can be the whole list, a sublist from randomly selected items, or a single randomly picked item from the list. This can be very handy as part of Test Data Management to construct dynamic HTTP responses that contain randomly selected values.
  • JSON, URL, XML, and HTML encoders for output values.
  • Any parameter can now be defined once and used without duplicating its definition in request matchers as well as in building dynamic HTTP responses.
  • The ‘libs’ configuration for a script executor is now optional in the YAML DSL.


We invite you to learn more about API Simulator, download and install it, and run the examples. Why not even create API simulations to help your own testing and development?
