Learning to type faster is an investment in efficiency. Whether you’re a gamer, a writer, or just spend hours at your keyboard, upping your typing speed can save you time and help with accuracy. But if you’re putting in the work to improve, why not get real insights into your progress? WhatPulse can help you track your keystrokes across different typing test sites and let you see the numbers stack up in real-time. Below, we’ll look at some of the best websites to improve your typing speed, with each offering its own features for keeping you engaged, motivated, and improving.

Automated unit test generation has been widely studied, but generating effective tests for dynamically typed programs remains a significant challenge. Existing approaches, including search-based software testing (SBST) and recent LLM-based methods, often suffer from type errors, leading to invalid inputs and assertion failures, ultimately reducing testing effectiveness. To address this, we propose TypeTest, a novel framework that enhances type correctness in test generation through a vector-based Retrieval-Augmented Generation (RAG) system. TypeTest employs call instance retrieval and feature-based retrieval to infer parameter types accurately and construct valid test inputs. Furthermore, it utilizes the call graph to extract richer contextual information, enabling more accurate assertion generation. In addition, TypeTest incorporates a repair mechanism and iterative test generation, progressively refining test cases to improve coverage. In an evaluation on 125 real-world Python modules, TypeTest achieved an average statement coverage of 86.6% and branch coverage of 76.8%, outperforming state-of-theart tools by 5.4% and 9.3%, respectively.
