// In these tests, we do the following:
|
||
|
|
// try for 200ms (rt=2)
|
||
|
|
// wait for 300ms
|
||
|
|
// try for 200ms (rt=1)
|
||
|
|
// wait for 300ms
|
||
|
|
// try for 200ms (rt=0)
|
||
|
|
// fail after 1200
|
||
|
|
// Actual time will be more like 1220-ish for setTimeout irregularity
|
||
|
|
// But it should NOT be as slow as 2000.
