c# - Get chrome's console log -

i want build automation testing, have know errors appear in console of chrome.

there option error lines appear in console?

in order see console: right click somewhere in page, click "inspect element" , go "console".

i don't know c# here's java code job, hope can translate c#

import org.openqa.selenium.webdriver; import org.openqa.selenium.chrome.chromedriver; import org.openqa.selenium.logging.logentries; import org.openqa.selenium.logging.logentry; import org.openqa.selenium.logging.logtype; import org.openqa.selenium.logging.loggingpreferences; import org.openqa.selenium.remote.capabilitytype; import org.openqa.selenium.remote.desiredcapabilities; import org.testng.annotations.aftermethod; import org.testng.annotations.beforemethod; import org.testng.annotations.test;  public class chromeconsolelogging {     private webdriver driver;       @beforemethod     public void setup() {         system.setproperty("webdriver.chrome.driver", "c:\\path\\to\\chromedriver.exe");                 desiredcapabilities caps = desiredcapabilities.chrome();         loggingpreferences logprefs = new loggingpreferences();         logprefs.enable(logtype.browser, level.all);         caps.setcapability(capabilitytype.logging_prefs, logprefs);         driver = new chromedriver(caps);     }      @aftermethod     public void teardown() {         driver.quit();     }      public void analyzelog() {         logentries logentries = driver.manage().logs().get(logtype.browser);         (logentry entry : logentries) {             system.out.println(new date(entry.gettimestamp()) + " " + entry.getlevel() + " " + entry.getmessage());             //do useful data         }     }      @test     public void testmethod() {         driver.get("http://mypage.com");         //do on page         analyzelog();     } } 

pay attention setup method in above code. use loggingpreferences object enable logging. there few types of logs, if want track console errors logtype.browser 1 should use. pass object desiredcapabilities , further chromedriver constructor , voila - have instance of chromedriver logging enabled.

after performing actions on page call analyzelog() method. here extract log , iterate through entries. here can put assertions or other reporting want.

my inspiration this code michael klepikov explains how extract performance logs chromedriver.
