Manual Testing
The idea of manual testing is pretty straightforward. Write some code, and then run your program. Did it work? Did it do what you expected it to do? As simple as that seems, manually testing is quite powerful. In manual testing, you are actually using the software you are writing. If you were building a chair, wouldn’t you try sitting on it to make sure it were comfortable and could support your weight (see Figure 12.1)? Other types of testing exist, but there is no substitute for actually using your software.
