Abstract: A method and a system to create a software test environment on demand are described. An example system includes a dependency module to, upon receiving a command identifying a primary function to be created in a test environment, identify one or more dependencies of the primary function. The dependencies are other functions or databases that the primary function depends upon. The dependency module generates a topology of the test environment that indicates the relationship of the dependencies to the primary function. A provisioning module provisions a plurality of pools based on the topology. An enterprise service bus (ESB) routing module updates ESB routing of the primary function to route to the plurality of pools in the test environment. A credentials module provides credentials of the pools in the test environment.
