Manual Versus Automation
Manual testing is important, especially early in the project when the UX and other features evolve quickly and when testability work and automation are underway.
Manual testing is also critical because a core value of Chrome OS is simplicity, and the UX needs to be pleasant and intuitive for the user. Machines still cannot test this.
Automation is key to the long-term success and efficiency of the test team and to guard against regressions. As automation is enabled in the browser, much of manual testing in priority and ROI order is also auto- mated.
