The webpage breaks when using recording in JMeter.
I started the Test script recorder and entered the URL in Firefox browser
(manual proxy config are done correctly in Firefox browser)
The page do not load correctly and gives error
When i see "View Result Tree" in workbench it shows following error various times
"javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca"
java.net.SocketException: Software caused connection abort: recv failed
I am new to JMeter. while giving instructions please explain it simply so that i can understand. Thanks
You must accept the Security rule exception when loading the first page in browser.
Also it is very helpful to install the CA certificate that JMeter generates in the browser, see:

Using:
JMeter version 5.4.1
Browsers:
MS Edge 94.0
Google Chrome: 94.0
FireFox: 92.0.1
Using JMeter to record .Net application. 90% of the recording was perfectly fine. no page crashed and received the response correctly. Except, when I made any requests that related to permission.aspx or permission.asp page I got error message have shown below or wrong response content displayed on the page.
I did try to change the record type from httpclient4 to Java but it didn't help.
Also Error log from JMeter log showed: Cause: java.io.IOExeption: Server returned HTTP response code: 500 for URL: https://xxxx.xx.xx.com/
USERID:
ASP.Net EXCEPTION:
StatusCode:
200
Error Message:
Exception of type 'System.Web.HttpUnhandledException' was thrown.
Inner Exception:
System.NullReferenceException: Object reference not set to an instance of an object.
Your question provide sufficient level of details so I doubt you will get a comprehensive answer, it looks like JMeter isn't capable of handling some specific setup of your application.
In order to get more information you could:
Increase logging level verbosity for JMeter's HTTP(S) Test Script Recorder by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.proxy" level="debug" />
then inspect jmeter.log file for any suspicious entries
Check your application logs as HTTP 5xx errors are server-side errors so most probably the reason can be found there
You might also want to try out an alternative way of recording a JMeter test: JMeter Chrome Extension which is kind of less "invasive" and "alien" to the browser than JMeter's proxy server.
I am new to JMeter and trying to record a JMeter script on firefox but getting an error message
Did Not Connect: Potential Security Issue
First make sure you have followed all the steps below and especially the browser side configuration:
https://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.html
If your site is HTTPS, I would suggest you to use Blazemeter Plugin for Chrome to record your tests without much hassles and then export it later into Jmeter.
1.Try to add the link to trusted sites.
-In Firefox go to the Open Menu (Upper right 3 lines)
-Locate and select the “Security” tab.
-Click on the “Exceptions…” button.
Next type in the internet address you would like to remain trusted EX:
*.test.com
-Click “Close” then “OK” to complete this action.
Try recording with chrome.
I have imported the certificate - ApacheJMeterTemporaryRootCA.crt
but still I am getting the below message and it doesn't record.
Please suggest.
Steps I followed:
Under Workbench, I have added a 'HTTP(S) Test Script Recorder' > then a 'Sample Controller'.
I am clicking the Start button in the 'HTTP(S) Test Script Recorder' to start recording.
I have set the Port to 8080 and same I have set in my IE web browser.
To be sure to setup correctly recording use Recording Template.
Then configure your browser to point to the proxy host / ports
Check it's ok by calling a page in browser BEFORE STARTING RECORDER, if you get proxy error then it's OK if you get the page, fix your proxy settings in Browser.
Start Browser
Call Https Page and accept exception

Is there a universal way to detect when a selenium browser opens an error page? For example, disable your internet connection and do
driver.get("http://google.com")
In Firefox, Selenium will load the 'Try Again' error page containing text like "Firefox can't establish a connection to the server at www.google.com." Selenium will NOT throw any errors.
Is there a browser-independent way to detect these cases? For firefox (python), I can do
if "errorPageContainer" in [ elem.get_attribute("id") for elem in driver.find_elements_by_css_selector("body > div") ]
But (1) this seems like computational overkill (see next point below) and (2) I must create custom code for every browser.
If you disable your internet and use htmlunit as the browser you will get a page with the following html
<html>
<head></head>
<body>Unknown host</body>
</html>
How can I detect this without doing
if driver.find_element_by_css_selector("body").text == "Unknown host"
It seems like this would be very expensive to check on every single page load since there would usually be a ton of text in the body.
Bonus points if you also know of a way to detect the type of load problem, for example no internet connection, unreachable host, etc.
WebDriver API doesnot expose HTTP status codes , so if you want to detect/manage HTTP errors, you should use a debugging proxy.
See Jim's excellent post Implementing WebDriver HTTP Status on how to do exactly that.
If you just need to remote-control the Tor Browser, you might also consider the Marionette framework by Mozilla. Bonus: It fails when a page cannot be loaded: (see navigate(url) in the API)
The command will return with a failure if there is an error loading
the document or the URL is blocked. This can occur if it fails to
reach the host, the URL is malformed, the page is restricted (about:*
pages), or if there is a certificate issue to name some examples.
Example use (copy from other answer):
To use with the Tor Browser, enable marionette at startup via
Browser/firefox -marionette
(inside the bundle). Then, you can connect via
from marionette import Marionette
client = Marionette('localhost', port=2828);
client.start_session()
and load a new page for example via
url='http://mozilla.org'
client.navigate(url);
For more examples, there is a tutorial.
