Hi parashuram, Am new in protractor. I have attached my project code. I have getting problem in your protractor-perf.
it('TC63634: should continue',function (callback){
console.log('TC63634: should continue...');
var perfRunner = new PerfRunner(protractor, browser);
perfRunner.start();
// browser.manage().timeouts().implicitlyWait(20000);
let con = element(by.buttonText('Continue'));
con.click();
perfRunner.stop();
if(perfRunner.isEnabled) {
console.log("perfRunner is enabled");
perfRunner.getStats('mean_frame_time').then(function(stats) {
console.log(stats)
});
expect(perfRunner.getStats('meanFrameTime')).toBeLessThan(30000);
};
callback();
});

I have used protractor-perf in this function. it’s getting this error
[20:39:58] I/launcher - 0 instance(s) of WebDriver still running
[20:39:58] I/launcher - chrome #01 failed 3 test(s)
[20:39:58] I/launcher - overall: 3 failed spec(s)

how to solve this?
my project verstions
"protractor": "~4.0.14",
"protractor-perf": "^0.2.3",
