I wrote a helper methods to add a network response listener over Puppeteer page instance. the code looks like this

let Helper = codecept_helper;

class CheckHelper extends Helper 
 async listenRequest(listener)
 
 const helper = this.helpers['Puppeteer'];
 await helper.page.setRequestInterception(true);
 helper.page.on("request",listener);
 return helper._waitForAction();
 
 async listenResponse(listener)
 
 const helper = this.helpers['Puppeteer'];
 helper.page.on("response",listener);
 return helper._waitForAction();
 


module.exports = CheckHelper;

then in the test script

 let self=this;
 I.listenResponse((response)=>
 if(response.url().match(/github.*.js/) && response.headers()['content-length']>1000) 
 //codeceptjs.event.emit(codeceptjs.event.test.failed, self, 'js file is too big!');
 //codeceptjs.recorder.throw('js file is too big!')
 //codeceptjs.recorder.stop();
 //throw new Error('js file is too big!')
 
 )
 I.amOnPage("https://www.github.com");

i first add response listener, then i goto "github", when some js file size is too big,i will throw out an error,in order too check content size is correctly.

however, even i throw error out (like the comments codes did), the main test flow just not stop, how do i do is the right way?

well,i found a solution later

i recorded all the page response into a custom object in the page instance.
later i wrote a help methods to check whole records.

//in helper.js
startRecordResponse() 
 const helper = this.helpers['Puppeteer'];
 helper.page.on("response", (res) => );
 return helper._waitForAction();


checkFileIsTooBig(filter, sizeLimit) 
 const helper = this.helpers['Puppeteer'];
 //use the data recorded in savedResponse object 
 Object.keys(helper.page.savedResponse).forEach((url) => (typeof filter == "string" && url.indexOf(filter) != -1)) && res.headers()['content-length'] > sizeLimit) 
 throw new Error(`file $url is too big,$res.headers()['content-length'] > $sizeLimit`)
 
 )
 return helper._waitForAction();

then in test file

Before((I) => 
 I.startRecordResponse();
 I.amOnPage("https://www.github.com");
);

Scenario('github_test', (I) => 
 //check a js file contain github is less than 100 bytes
 I.checkFileIsTooBig(/github.*.js/,100);
 
);
