The length of the scroll bar changes in time according to the length or width of the displayed information , This helps the user understand the location and percentage of the information displayed , Such as word browse 100 Page document , Browse to 50 When the page , The scroll bar should be in the middle
2. Drag the scroll bar , Check screen refresh , And check for garbled code
3. Click the scroll bar
4. Use the scroll wheel to control the scroll bar

Various controls are mixed in the form

Test point

1. Interaction between controls
2. tab The order of the keys , It's usually from top to bottom , From left to right
3. The use of hotkeys , Test one by one
4. enter Key sum esc The use of keys

In the test , We should follow the principle from simplicity to complexity , First, test the function of a single control , After making sure it's all right , Then test the function combination of multiple controls

ps： When testing the password input box, you should pay special attention to the test of uppercase input
