1. A computer-implemented method, comprising: executing an automated computer test case that indicates a set of actions to be executed; receiving an indication of a first action of the set of actions at an action broker while executing the test case, the action broker performing the following acts in response to receiving the indication of the first action: choosing a first automation implementation to execute the first action; sending a request to the first automation implementation to execute the first action through a first action execution path; and receiving a result from the execution of the first action through the first action execution path; and receiving an indication of a second action of the set of actions at the action broker while executing the test case, the action broker performing the following acts in response to receiving the indication of the second action: choosing a second automation implementation to execute the second action; sending a request to the second automation implementation to execute the second action through a second action execution path; and transmitting the result from the execution of the first action to the second automation implementation for use in executing the second action through the second action execution path.
