Description
The performance mock currently return an empty object which mean calling
new Performance
will run into error during test.I feel like I am not getting to the root of the issue with this solution.
Musing 1:
I think the performance mock come with jsdom, which only mock a portion of the API in
performance
but this does not explain why the mock is an empty object.Musing 2:
we are using
performance.timing
, but checking forPerformanceNavigationTiming
before use. Should we check forPerformanceTiming
as well?Musing 3:
PerformanceTiming
is deprecated 😂, should the code be updated to useperformance.navigation
instead? Although the official types havetiming
andnavigation
type listed as deprecatedType of change
