A mock server implementation for discovery applications is provided. A computing system includes a mock server, which receives a client request from a mock client on a discovery server. The client request corresponds to a user query associated with a discovery of resources on a remote computing system. The mock server determines a first response from a mock response dataset. The first response to the client request is determined based on the received client request. The mock response dataset includes a set of responses associated with a sequence of operations executed in the past for the discovery of resources on the remote computing system. The mock server transmits the determined first response to the mock client on the discovery server. The mock client receives the transmitted first response and sends the received first response to a discovery application interface on a user device.
