A computer-implemented method for automated verification of a software program in a behavior-driven development environment, the method comprising: receiving, with a data processing system, test scenarios, each test scenario defining an expected behavior of the software program in consecutive test steps, which are formulated in a domain-specific language using natural language phrases and which describe a desired outcome of the software program for predefined events based on given initial conditions; importing test step definitions from the behavior-driven development environment; determining for each test step of the test scenarios if the test step matches with one of the test step definitions on basis of the natural language phrases of the test step; assigning all matched test steps to the corresponding test step definitions; applying natural language processing, NLP, on the natural language phrases of any test steps remaining unmatched, wherein the NLP provides a confidence level for each unmatched test step to correspond to one of the test step definitions; assigning any unmatched test step to the corresponding test step definition when the confidence level surpasses a first predefined matching probability; and at least one of: generating graphical test models for the test scenarios on basis of the assigned test step definitions; and generating executable test scripts for the test scenarios on basis of the assigned test step definitions; further comprising: updating, when the confidence level is above the first predefined matching probability, the respective test step definition on basis of the natural word phrases of the respective test step; and adding, when the confidence level is below a second predefined matching probability, a test step definition to the behavior-driven development environment corresponding to the respective test step. receiving, with a data processing system, test scenarios, each test scenario defining an expected behavior of the software program in consecutive test steps, which are formulated in a domain-specific language using natural language phrases and which describe a desired outcome of the software program for predefined events based on given initial conditions; importing test step definitions from the behavior-driven development environment; determining for each test step of the test scenarios if the test step matches with one of the test step definitions on basis of the natural language phrases of the test step; assigning all matched test steps to the corresponding test step definitions; applying natural language processing, NLP, on the natural language phrases of any test steps remaining unmatched, wherein the NLP provides a confidence level for each unmatched test step to correspond to one of the test step definitions; assigning any unmatched test step to the corresponding test step definition when the confidence level surpasses a first predefined matching probability; and at least one of: generating graphical test models for the test scenarios on basis of the assigned test step definitions; and generating executable test scripts for the test scenarios on basis of the assigned test step definitions; further comprising: updating, when the confidence level is above the first predefined matching probability, the respective test step definition on basis of the natural word phrases of the respective test step; and adding, when the confidence level is below a second predefined matching probability, a test step definition to the behavior-driven development environment corresponding to the respective test step. generating graphical test models for the test scenarios on basis of the assigned test step definitions; and generating executable test scripts for the test scenarios on basis of the assigned test step definitions; further comprising: updating, when the confidence level is above the first predefined matching probability, the respective test step definition on basis of the natural word phrases of the respective test step; and adding, when the confidence level is below a second predefined matching probability, a test step definition to the behavior-driven development environment corresponding to the respective test step. updating, when the confidence level is above the first predefined matching probability, the respective test step definition on basis of the natural word phrases of the respective test step; and adding, when the confidence level is below a second predefined matching probability, a test step definition to the behavior-driven development environment corresponding to the respective test step.
