| General test notes: |
| |
| All tests which write data into a socket write i%256 into byte i, which is |
| verified by readers. |
| |
| In general there are a few interesting things to vary which may lead to |
| exercising different codepaths in an implementation: |
| 1. Total amount of data written to the socket |
| 2. Size of slice allocations |
| 3. Amount of data we read from or write to the socket at once |
| |
| The tests here tend to parameterize these where applicable. |
