Various methods, apparatuses/systems, and media for automatically generating tests in Gherkin format are disclosed. A repository stores open application programming interface (API) specification definition file corresponding to an application. A processor accesses the repository to obtain the open API specification definition file as input data. A receiver receives the input data. The processor parses, in response to received input data, the specification to collect data from the open API specification definition file; structures the collected data into a data frame object; implements a processing logic to derive applicable tests using a predefined template; implements the tests by utilizing the predefined template; and automatically generates, based on the implemented tests, corresponding test cases in an executable Gherkin syntax. This process of automatically executing testing of the application based on the functional tests is performed, for example, on a Kubernetes platform.
