During a test-generation technique, a test session with web flows associated with a set of users and a browser is recorded. Then, the test session is modified to generalize the web flows to a larger set of users. For example, data may be converted into variables, requests may be added or removed, and/or delays may be inserted between requests. In addition, the test session may be filtered using one or more filters to remove: static content, images and/or types of requests. After the test session has been generalized, it can be incorporated into a load test that accurately simulates interactions with multiple users.
