Fix Wasm.Performance benchmark invalid Locale

[LoopedBard3]

Fix BlazorWasm test invalid Locale

Update Wasm.Performance benchmark to explicitly set Locale to en-US.

Description

Update Wasm.Performance benchmark to explicitly set Locale to en-US when browsing to the benchmark page to fix an invalid culture identifier (en-us@posix) error being hit in the ASP.NET Performance lab.

Fixes #64450

The local test still gives the following error but it seems to be after all of the testing, when the container shutsdown:
[Browser Log]: Failed to load resource: net::ERR_CONNECTION_RESET

Full local test log:

I have tested this locally and was able to successfully run the BlazorWasm test docker container.

Pull request overview

This PR fixes an invalid culture identifier error (en-us@posix) in the ASP.NET Performance lab by explicitly setting the browser locale to "en-US" when creating a new Playwright page in the Wasm.Performance benchmark driver.

• Updates the NewPageAsync call to include locale configuration

[pavelsavara]

an invalid culture identifier (en-us@posix) error being hit in the ASP.NET Performance lab.

@ilonatommy any idea where the "posix" part is coming from ? Are there other customers suffering from that ?

[Browser Log]: Failed to load resource: net::ERR_CONNECTION_RESET

I guess this is a timeout after Mono/Wasm runtime failed to start, right ?

I don't know, this? microsoft/playwright#34046

[Browser Log]: Failed to load resource: net::ERR_CONNECTION_RESET

I guess this is a timeout after Mono/Wasm runtime failed to start, right ?

It is not clear to me where this error is coming from especially with the test seeming to run properly to completion with Done executing benchmark being printed. I tried doing a test run with a favicon properly included as that was giving 404's when opening the page in my browser, which did get rid of the 404, but did not fix the Failed to load resource... error.

[pavelsavara]

which did get rid of the 404

Yeah, icon is requested by the browser itself. It doesn't matter if it's there or not.

but did not fix the Failed to load resource... error.

Can you see something interesting in the network tab of the chrome dev tools ? There is Initiatior column which could give us some clue.
