|  | </head> | 
|  | <body> | 
|  | This is the test for basic functionality of heap snapshot view grid. | 
|  | <br> | 
|  | <br> | 
|  | To use this test: | 
|  | <ul> | 
|  | <li>load file in the browser; | 
|  | <li>open DevTools (Ctrl+Shift+I on Win/Linux, Command+Option+I on Mac); | 
|  | <li>go to 'Profiles' page; | 
|  | <li>press 'Take heap snapshot' button | 
|  | (eye icon on the left side of status bar); | 
|  | </ul> | 
|  | <br> | 
|  | On the left pane under 'Heap snapshots' section, an item called | 
|  | 'Snapshot 1' must appear, and a grid with snapshot data must | 
|  | appear on the right. Now test the following functionality in the grid: | 
|  | <ul> | 
|  | <li>change sorting order in each column by clicking on its header; | 
|  | <li>resize each column; | 
|  | <li>toggle between showing absolute times and percents | 
|  | (button with percent sign on the status bar); | 
|  | <li>double-click on numbers in 'Count' and | 
|  | 'Size' columns to toggle between times and percents for | 
|  | this column only; | 
|  | <li>expanding and collapsing tree nodes. | 
|  | </ul> |
