testing timing issues of my API

[RiFa]

Hello,

I know that the API I'm testing with Cypress has a problem when two calls are sent that are too close (in time) to each other.

I would like to write a flow in Cypress where  the same call can be made within X milliseconds and the two results are shown.

I would like to play with interval X to see when the API breaks and whether our fix works.

Could someone let me know if there is a way to do this?

Thanks,

R

Hi,

I think we could do something like

 uint32_t delay_ms = 1 ; // change this value for testing...
 
  my_api() ;
  CyDelay(delay_ms) ;
  my_api() ;

But meantime, I suppose that most of APIs should have a way to check if the process of that API is done.

By any chance, can you provide the name of the API you'd like to test?

Hi @MotooTanaka , thank you for your input. Is there a way to monitor, get back, when each call is actually sent out?

Sorry, this is our proprietary API in a microservice-based application.

Cheers,

Hi @RiFa, 

Can you provide some details about the API that you are testing? Is it an interrupt driven function which returns before it completes? Or is the application using an OS like FreeRTOS?

Best regards,

Hello @Hari ,

thank you for looking into this. To be honest, I'm the PO and I don't have this type of information (other than I call a REST API and get back something).

Generally speaking, I just would like to know how to send out two API calls from Cypress spaced by X ms (X being my (reasonable) choice) and how to verify at what time each call was sent out.

Is that possible?

Thank you in advance,

RiFa

Hi @RiFa 

The simplest way to achieve this would be with the help of a delay. This would make it a blocking operation and in case you need it to be non-blocking, you can use a timer as well. But in both the cases, only one function would be active at a time.
