Gleb Bahmutov's blog post outlines a method to obtain individual test results immediately after each test is completed in Cypress, eliminating the need to wait for an entire test run to finish. This approach is particularly useful to promptly identify any failed tests, thus saving time. The method involves setting up an inter-process communication (IPC) server named "cypressListener" using Node.js to receive and print test results in real-time. The process begins with executing tests through an index.js script, which uses the Node IPC module to communicate test outcomes from the browser-based Cypress Test Runner to the Node.js environment. This involves a series of steps where test attributes are saved and sent to a plugins process via Cypress's cy.task command, which then forwards them to the cypressListener process using IPC emit commands. The detailed instructions include setting up a connection between the Cypress Test Runner and the Node environment, ensuring each test's state, title, and duration are communicated and displayed instantly, providing a practical solution to improve test efficiency and responsiveness.
