emulator.wtf has minute-precision billing, invoiced on a monthly basis. Here’s a few examples how the total cost of a test is calculated.
Only the actual test runtime is measured with the purpose of billing. Test preparation or teardown, including but not limited to uploading APKs, starting devices, pushing files or APKs to the device, pulling files after the test has finished or tearing down the device are not billed.
The test duration is measured at a minute precision and always rounded up
ceil) to the next minute. If a test takes exactly a whole number of minutes
then it is still rounded up. A few examples:
- A test taking 165.813 seconds is billed as 3 minutes
- A very fast test taking 1.169 seconds is billed as 1 minute
- A test taking exactly 240.000 seconds is billed as 5 minutes
Every device-shard combination is rounded up separately. For example, a test
having two shards and two device models (
4 separate emulators in total) and
150 seconds on each emulator will be billed according to
3 * 4 - 12 minutes in total.
Our current billing cycle is one calendar month. At the end of the billing cycle, or minutes consumed are added up, divided by 60, multiplied by your hourly price and then rounded up to the nearest cent precision.
For example, if you consumed
95 test minutes in June and have an hourly price
$2 per emulatorhr then the number on the final invoice at the end of the
billing cycle will be
95 / 60 * 2 rounded to the cent precision, $3.17.
