Optimizing Elixir Tests in VS Code

Peter Solnica shares a technique for accelerating test runs in Elixir using Visual Studio Code's functionality. By setting up custom tasks and assigning key bindings, developers can execute tests quickly, which is essential for a smooth and rapid iteration process. The method involves configuring a 'tasks.json' file with custom tasks like running all tests, testing the current file or line, and debugging a current line with an 'iex' session. Subsequent key bindings facilitate immediate test execution and debugging actions. Solnica emphasizes how this approach enables greater focus on coding and improvement without depending on numerous extensions.
