Abstract

Automated software-testing systems and computer program products use mock software entities to perform integration testing on a microservices-based application. The mock entities emulate the behavior of other microservices or external software applications that would normally interact with the tested microservices in a production environment. The mock entities are managed by a mock server that communicates with the test system through a messaging system. The mock server determines how the mock entities should respond to the tested application's service requests by referring to test guidelines stored in a behavior store. During testing, the test system dynamically updates the behavior store in response to the tested application's service requests and to other indicators of the current state of the tested application. If the tested application interacts with the mock entities during the test as expected, the test system deems the application to have passed the integration test.

Dependent claims

An automated application-testing system comprising a processor, a memory coupled to the processor, and a computer-readable hardware storage device coupled to the processor, the storage device containing program code configured to be run by the processor via the memory to implement a method for automated integration testing with mock microservices, the method comprising:

the processor accepting from the automated application-testing system a request to perform an integration test upon a tested set of microservices, where the tested set of microservices is comprised by a tested application;
the processor launching a mock server;
the processor directing the mock server to launch and maintain a mock entity,
where the mock entity emulates an operation of a software entity that is not a subject of the integration test, and
where the software entity is known to interact with at least one microservice of the set of microservices in a production environment;
the processor receiving from the mock server a first service request that had been communicated to the mock entity by the tested set;
the processor sending to the tested set, in response to the receiving, a service response to a most recently received service request, where the sending comprises communicating the service response to the mock server and the mock server directing the mock entity to forward the service response to the tested set;
the processor receiving from the mock server an additional service request at a time later than a time of the receipt of the first service request;
the processor repeating the sending in response to the processor receiving the additional service request;
the processor determining, from the receiving of the additional service request, that the tested set is operating correctly;
and
the processor returning to the automated application-testing system a notification that the tested set has passed the integration test.
