I am writing an automated test script. So far, Selenium has helped me. Now,I have a test case where I should tamper the request and add a parameter and then submit the request. I did it manually by using tamperdata.
I want to automate this test case now. The problem is, selenium is not recording my actions of adding a parameter and then submitting the request. I understand selenium is a record-playback kind of tool. can some one confirm me if it cannot record tamper data or am doing wrong?
If it cannot, how do you people automate these kind of test cases.
Selenium really is not designed for such a type of work. If a regular user can't make a tampered request (without Firebug etc.), then Selenium usually can't, too. Anyway, you can have FireBug: How do I run Firebug within Selenium WebDriver (Selenium 2)?. Controlling it, that's where the problems come - and I don't think it's worth the research.
One way to do this could be HttpUrlConnection in Java, making and sending the request in Java ... see those SO questions: How to send HTTP request in java?, Using java.net.URLConnection to fire and handle HTTP requests

i am still new to JMeter and i was assigned to a work that I will need to use JMeter to perform automation testing. The idea is to write script using JMeter and run the script to fill in the forms in the website. I was curious that can JMeter use different data from the database to fill in the form of the website everytime it execute?(unique data for every user)
I have followed this tutorial (https://www.blazemeter.com/blog/fill-forms-and-submit-with-jmeter-made-easy/ ) and it succeed, however, when i try to change the parameter name (to some other names that do not matches the field name found in the inpect mode), it still works. So i was wondering how JMeter knows where to put in the parameter even i have change to a wrong field name?
As per JMeter Project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
Browsers don't do any magic, they execute HTTP Requests, wait for response and render it. JMeter in its turn can execute the same HTTP requests so traffic would be the same, however it will not render the response, but rather measure the time and collect some more metrics.
If you change the names of the inputs in the form most probably the request will be successful, to wit you will get HTTP Status Code below 400 hence JMeter will mark the result as "green", however if you inspect the response using View Results Tree listener you will see that the form is not filled and/or you still at the same page.
If you want to use JMeter for checking the data returned by the application you're testing consider using JMeter Assertions to test presence of expected values, absence of errors, set response time thresholds, etc.
You can automate the form submission or order placement usin JMeter. You can JMeter for API testing as well by adding assertions. But the main purpose of the JMeter is to test the performance of the application. Its not like selenium which performs actions on the browser whereas JMeter sends the request in various protocols to relevant server and can also simulate many users at the same time.
If you want to do extensive automation testing,JMeter isnt the ideal tool for that.
You can use webdriver sampler to run the selenium with jmeter. It requires to configure sampler and browser config which are plugin and can be downloaded using plugin manager.
For more info:-https://www.blazemeter.com/blog/jmeter-webdriver-sampler/
Now, without the plugin it is working on protocol level and not on the frontend as pointed out in the above comments.
So, yes it can depend on which layer you want to work. It can work on frontend like selenium using the webdriver plugin and can submit the form with different data as a direct request to the server without using the frontend/GUI.
Hope this helps.
It depends on what you are trying to automate. If you plan to automate API invocation where there are some pre-requisites like grabbing tokens, cookies, session IDs from the browser, then JMeter can probably be used where existing JMeter capabilities can be leveraged using BeanShell scripting and other plugins.
But if you plan to have a full blown UI automation framework then JMeter might not be an ideal choice.
Is it possible to rerun the tests created in the post response test without
resubmitting the request?
For example you submit an API request in Postman, then it comes back with
some data.
I want to just re-run the scripts against this data.
Could be really useful in debugging these post-response scripts.
I want to rerun Tests in area 1 without hitting the Send button
(area 2). That way I can test the javascript correctness of my Test scripts without having to wait for server responses.
You can use https://postman-echo.com/post and their API will echo the request you send. So basically you create the actual request once and then use the result in the ECHO call to do the development.
More info here:
https://docs.postman-echo.com/?version=latest
I'm afraid there is no better way at the moment.
I was looking for the same thing and came across this tip on the PostMan Community.
https://community.postman.com/t/re-run-test-script-without-re-sending-request/9160/8
Basically you:
Make your request
Save your response as an example
Create a PostMan mock from that response
Rerun and build up your test against the mock (and any variants, like failure cases)
Run against the original and verify everything is good.
While this workaround helps get the job done, I do wish that they could just make it so that you could hold the original state of the response and the env, run your tests, reset to the original state, rerun your tests and tweak until it all works.
You can write test entire test or the part you want to execute twice in a function and call that function 2 times, that the easy and low effort and maintenance way I am looking
I am a QA automation analyst responsible for testing a multi-platform online banking application. For our automation testing we use RubyMine suite with Gherkin/Cucumber, Ruby-scripted steps and Selenium-webdriver, Watir and page-object gems/libraries.
I have a number of scripts that I cannot automate completely without manual intervention, and these include blocking certain network calls through Telerik Fiddler to produce warning pages or error messages, etc. The future of our automation would be to do this through RubyMine instead of Fiddler for network blocking. I know there is a way to do this in Chrome using Inspect Element and the Network menu using enable request blocking. However, I cannot figure out a way to force Chrome through Ruby/Selenium to block a given request. The only way is do manually do it myself, and therefore I can't actually automate these as wanted.
So, my question -- is this a possibility to automate request-blocking with Selenium-webdriver? And, if so, where should I begin to look for help with this?
Thanks.
To block URLs from loading with Selenium with the DevTool API:
def send_cmd(driver, cmd, params={})
bridge = driver.send(:bridge)
resource = "session/#{bridge.session_id}/chromium/send_command_and_get_result"
response = bridge.http.call(:post, resource, {'cmd':cmd, 'params': params})
raise response[:value] if response[:status]
return response[:value]
end
send_cmd(driver, "Network.setBlockedURLs", {'urls': ["*"]})
send_cmd(driver, "Network.enable")
It's not very well documented, but you can also implement request blocking by passing the host-resolver-rules option to chrome and mapping the domain to localhost or an invalid IP. Something like this should work for you:
options = Selenium::WebDriver::Chrome::Options.new
options.add_argument('--host-resolver-rules=MAP www.google-analytics.com 127.0.0.1')
driver = Selenium::WebDriver.for :chrome, options: options
For those wanting to know, python version is just:
driver.execute_cdp_cmd('Network.setBlockedURLs', {"urls": ["www.baidu.com"]})
driver.execute_cdp_cmd('Network.enable', {})
Try https://github.com/lightbody/browsermob-proxy
I dont know if it can satisfy your requirement as I am no way a network expert, I do use browsermob-proxy extensively to capture network request along with selenium and there is a method to blacklist certain request

How to disable loading external urls on seleniumlibrary/robotframework
I wanted to know if JMeter has a option where you wait until some element disappears.
Example a loading bar only once that has completed or no longer visible then to carry on. (Also being able to monitor the length of time taken)
I have through about writing it as a webdriver test and then running it as a Junit test in JMeter but wanted to know if there is a simpler solution.
Any ideas welcome :)
First of all you need to realize that JMeter is not a browser
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So JMeter doesn't execute any client-side JavaScript, the only way of implementing "wait until" option is using While Controller in order to re-execute the same request again and again until response data will contain (or stop containing) the element you're looking for.
If you need to evaluate client-side JavaScript the only option would be going for Selenium. I would recommend using WebDriver Sampler instead of going for JUnit as this way you won't have to recompile your script for any change, it will be inlined into .jmx
You can use Transaction Controller to monitor the time taken by the whole process and to wait for a change , have a look at this:

I'm trying to start a Selenide test with a POST request to my application.
Instead of a simple open(/startpoint)
I would like to do something like open(/startpoint, stuff=foo,stuff2=bar)
Is there any way to do that?
I'm asking this because the original page which posts to this start point depends on external providers that are often offline (development environment) and so will often fail too early (and are not the subject of the test)
No, Selenium doesn't have the ability to do a POST request, unless you loaded a dummy HTML page with a <form> tag on it (as a unit test) and a submit button (such as src/test/resources/FormPage.html). So, the alternative is to build a HTTP post query from scratch using Apache HttpUtils library. I usually use the latter method (as an integration test), although the former would work I think.
