I am using the test framework ava and I have two ways of setting a timeout. Either through command-line via --timeout and also by code via t.timeout(..)
The documentation states:
AVA resets a timer after each test, forcing tests to quit if no new test results were received within the specified timeout.
For the code t.timeout it says:
These timeouts are reset each time an assertion is made.
I don't understand if I should use both, or only one timeout setting. And does t.timeout also mean that if I set it to 1000 milliseconds that two consecutive t.is(..) assertions must be made within a second otherwise the test fails?
Do you need to set a timeout?
It can be useful, if you know a test will have failed after N seconds, but you don't want to wait the 30 seconds before you hit a default timeout. But that only applies in specific scenarios.
Similarly,
t.timeout()can be useful if your test does something asynchronous, and you want the test to fail if that takes too long. But again, it's rare for that to be useful.
