| 45 This is the test for heap snapshot comparison functionality. | |
| 46 <br> | |
| 47 <br> | |
| 48 To use this test: | |
| 49 <ul> | |
| 50 <li>load file in the browser; | |
| 51 <li>open DevTools (Ctrl+Shift+I on Win/Linux, Command+Option+I on Mac); | |
| 52 <li>go to 'Profiles' page; | |
| 53 <li>press 'Take heap snapshot' button | |
| 54 (eye icon on the left side of the status bar); | |
| 55 <li>press | |
| 56 <input type="button" name="changeStuff" value="this button" onclick="cha
ngeStuff()" />; | |
| 57 <li>press 'Take heap snapshot' button again; | |
| 58 </ul> | |
| 59 <br> | |
| 60 On the left pane under 'Heap snapshots' section, items called | |
| 61 'Snapshot 1' and 'Snapshot 2' must appear. Select 'Snapshot 2'. | |
| 62 Ensure that absolute values are shown (not percents). | |
| 63 <br> | |
| 64 <br> | |
| 65 TEST 1. Verify the following: | |
| 66 <ul> | |
| 67 <li>the value in '+/- Count' column for 'A' must be '-25'; | |
| 68 <li>after expanding 'A' item, the value in '+/- Count' column | |
| 69 for 'Array' child entry must also be '-25'; | |
| 70 <li>the value in '+/- Count' column for 'B' must be '+25'; | |
| 71 <li>after expanding 'B' item, the value in '+/- Count' column | |
| 72 for 'Array' child entry must also be '+25'; the value for 'A' | |
| 73 child must be '-25'; | |
| 74 </ul> | |
| 75 <br> | |
| 76 TEST 2. Change display to percent view (using the percent button on the | |
| 77 status bar). Verify the following: | |
| 78 <ul> | |
| 79 <li>values in '+/- Count' and '+/- Size' columns for 'C' must be 'deleted'
; | |
| 80 <li>values in '+/- Count' and '+/- Size' columns for 'D' must be 'new'; | |
| 81 </ul> | |
