To get more realistic for performance add the throttling settings. For me it works. :)
const lighthouseConfig = {
formFactor: "desktop",
screenEmulation: {
mobile: false,
disable: false,
width: Cypress.config("viewportWidth"),
height: Cypress.config("viewportHeight"),
deviceScaleRatio: 1,
},
throttling: {
rttMs: 40,
throughputKbps: 11024,
cpuSlowdownMultiplier: 0,
requestLatencyMs: 0,
downloadThroughputKbps: 0,
uploadThroughputKbps: 0,
},
};

Lighthouse is better than jmeter or it is completed different? Regards

[@joanmedia]

Hi Jorge! I think they are completely different.
Lighthouse is going to give you an score, Jmeter can provide you with more possibilities, configurations and results. Hope I can review a bit of Jmeter soon :)

[@marijanarukavina9499]

@JoanMedia
I followed your steps and I am using Cypress with Typescript, but I put the performance tests into the js files and I get this error:
cy.task('lighthouse') timed out after waiting 60000ms
node_modules/@cypress-audit/lighthouse/src/command-handler.js:46:1
44 | cy.log("-------- cy.lighthouse --------");
45 | return cy
> 46 | .task("lighthouse", {
| ^
47 | url,
48 | thresholds: thresholds || configThresholds || defaultThresholds,
49 | opts: opts || globalOptions,
Can you please help?

[@KevinOsterkilde]

Increase the task timeout to something like 3 minutes or however long is needed for your particular test: `Cypress.config('taskTimeout', 180_000);`

[@amardeeppatil5444]

[@arsicpedja]

Is this included in your Cypress udemy course?

[@joanmedia]

Hello Predrag. It is not but it is a good idea to include it, will be working on the new lecture for the next "release". I am constantly updating it.

[@arsicpedja]

@@joanmedia great, thank you. Will be looking into your course to improve my Cypress knowledge.
