Do automated testing tools make testing easier?

Yes and no. For larger projects, or ongoing long-term projects, they can be valuable. But for small projects, the time needed to learn and implement them is usually not worthwhile.

A common type of automated tool is the record/playback type. For example, a test engineer clicks through all combinations of menu choices, dialog box choices, buttons, etc. in a GUI and has an automated testing tool record and log the results. The recording is typically in the form of text, based on a scripting language that the testing tool can interpret. If a change is made (e.g. new buttons are added, or some underlying code in the application is changed), the application is then re-tested by just playing back the recorded actions and compared to the logged results in order to check effects of the change. One problem with such tools is that if there are continual changes to the product being tested, the recordings have to be changed so often that it becomes a very time-consuming task to continuously update the scripts. Another problem with such tools is the interpretation of the results (screens, data, logs, etc.) that can be a time-consuming task. You CAN learn to use automated testing tools, with little or no outside help.
