I am new to Jmeter and trying to do a while loop operation with a condition. So please someone provide solution for the below query.
Query: I am trying to do DELETE request for 50 times using the id as reference. So I kept the condition as "${startId}<=${endId}" in the while loop. But the while loop is executing infinitely. Is there any simple mechanism to iterate the loop for 50 times by increment the startId till it reaches endId.
While Controller accepts function or variable. So you need to either:
provide a variable which has value of "true" and becomes "false" somewhere else
provide a function which returns "false" to exit from While loop.
With your condition it won't evaluate your expression hence it will never become "false". The solution is to wrap your statement into i.e. __javaScript function as:
${__javaScript(${startId}<=${endId},)}
For more information on JMeter functions see How to Use JMeter Functions post series.
You may take help of loop controller and pre-processor.

If I use a JSR223 Preprocessor with the following code:
log.info("" + ${rand});
where ${rand} is a random variable, how can I make this variable change every time I loop this thread?
Changing the number of threads will indeed have the variable change each run, with loop it just takes one value and keeps it for all the other loops.
Putting it in a JSR223 Sampler yields the same result. I basically want the code to behave as a User Parameter.
Don't inline JMeter Functions or Variables in JSR223 Test Elements because:
They may resolve into something which will cause compilation failure
The syntax conflicts with Groovy's GStrings feature
If you tick Cache compiled script if available box the first occurrence will be cached and used on subsequent iterations, if you don't - you will loose performance benefits of Groovy
When using this feature, ensure your script code does not use JMeter variables or JMeter function calls directly in script code as caching would only cache first replacement. Instead use script parameters.
So:
Either move your ${rand} variable to "Parameters" section and change your code to
log.info("" + Parameters);
or use vars shorthand to JMeterVariables class instance, in this case change your code like:
log.info("" + vars.get("rand"));
You need to use vars to avoid getting cached/same value
vars.get("rand")
See JSR223 Best practices
script does not use any variable using ${varName} as caching would take only first value of ${varName.. Instead use vars.get("varName")
We have scenario where two variables are extracted from two samplers, and these variables needs to be compared. For this, have created two samplers with each one having 1 regex with matchno: -1, and used ForEach controller>under it 'counter' been used where i have used function ${__evalVar(test_${test_all})}
For this, need to store this ${__evalVar(test_${test_all})} value to a variable so that can be re-used in other places to compare.
Is storing a value from the __evalVar function possible and how can it be achieved?
There is __jexl3() function which can evaluate your expression and store the value into a variable of your choice, i.e. varFromJexl3:
${__jexl3("${__evalVar(test_${test_all})}",varFromJexl3)}
You can consider switching to __groovy() function which is probably the most powerful and flexible JMeter Function I can think of. The relevant syntax to evaluate test_${test_all} variable and store it into varFromGroovy variable would be something like:
${__groovy(vars.get('test_' + vars.get('test_all')), varFromGroovy)}
Demo:
Explaine me, please, what is the difference between those three variants of code? They all are working well.
Or maybe the first and second variant are identical?
What about the third one: I read that "browser.sleep()" is better to avoid in code, as it cause unstabilities in tests work. Is it true?
Help me to understand.
Thanks.
var MenuSigninButton = $('button.btn');
var LoginDropdownForm = element(by.id('loginForm'));
MenuSigninButton.click();
browser.wait(EC.visibilityOf(LoginDropdownForm));
and
MenuSigninButton.click();
browser.wait (function () {
return LoginDropdownForm.isDisplayed()
});
and
MenuSigninButton.click();
browser.sleep(3000);
expect(LoginDropdownForm.isDisplayed()).toBe(true);
First of all, yes, you should avoid use driver.sleep() as long as you can. Why?
Well, if you started to use that is because you are waiting something to appear on the screen in order to continue the execution of the test.
Well, you don't know how much time it will last that "something" to appear.
Maybe sometimes the time that you hardcoded is too short, and the test will fail, giving a fake result.
Maybe, the time is too long, and the test will last too much, and you could save that time.
Sometimes, the two points above could happen depending on time, overall load of the env,...
Second question:
When you use browser.wait(), you have to pass a condition to stop the wait.
It can be a Promise that will be solved on the future(not covered on your examples), it can be a condition(First example) or it can be a function, that has to be executed (Second example).
The third example is a bit different:
When you use the expect method, you are explicitly writing a condition that must pass in order to pass the test. For that reason, expect does not ends until the Promise inside it is resolved.
I have a requirement where I need to validate cases that gets matches with the output JSON: I wrote code inside if controller:(so if all the cases matches, we will say pass and print the value) And its actually working fine..
("${C_etrTimestamp}"=="${ETRTIMESTAMP}")&&("${C_EventName}"=="${EVENTNAME}")&&("${C_EventType}"=="${EVENTTYPE}")&&("${C_AreaName}"=="${AREANAME}")&&("${C_AreaType}"=="${AREATYPE}")&&("${C_additionalInfo}"=="${ADDITIONALINFO}")&&("${C_resultStatusCode}"=="${RESULTSTATUSCODE}")&&("${C_resultStatusMessage}"=="${RESULTSTATUSMESSAGE}")
But I also need to print the results those doesn't matches: so I created another if controller. and inside that I wrote the below code:(but its not working for me) so the 1st if is getting executed. but the results those are not matching are not getting entered into the 2nd if controller.
("${C_etrTimestamp}"!=="${ETRTIMESTAMP}")or("${C_EventName}"!=="${EVENTNAME}")or("${C_EventType}"!=="${EVENTTYPE}")or("${C_AreaName}"!=="${AREANAME}")or("${C_AreaType}"!=="${AREATYPE}")or("${C_additionalInfo}"!=="${ADDITIONALINFO}")or("${C_resultStatusCode}"!=="${RESULTSTATUSCODE}")or("${C_resultStatusMessage}"!=="${RESULTSTATUSMESSAGE}")
can anyone suggest me what to do?
Instead of trying to negate every clause, make a second condition an exact opposite of the first with `!(...):
!(("${C_etrTimestamp}"=="${ETRTIMESTAMP}")&&("${C_EventName}"=="${EVENTNAME}")&&("${C_EventType}"=="${EVENTTYPE}")&&("${C_AreaName}"=="${AREANAME}")&&("${C_AreaType}"=="${AREATYPE}")&&("${C_additionalInfo}"=="${ADDITIONALINFO}")&&("${C_resultStatusCode}"=="${RESULTSTATUSCODE}")&&("${C_resultStatusMessage}"=="${RESULTSTATUSMESSAGE}"))
You could also simplify conditions to one comparison with all variables inside it (since you want all of them to match), make is a bit shorter and easier to read.
First If:
"${C_etrTimestamp}${C_EventName}${C_EventType}..."=="${ETRTIMESTAMP}${EVENTNAME}${EVENTTYPE}..."
Second If:
!("${C_etrTimestamp}${C_EventName}${C_EventType}..."=="${ETRTIMESTAMP}${EVENTNAME}${EVENTTYPE}...")
So I have a keyword driven framework that executes on keywords. In one of the functions I have a if element exist condition. Now if that element doesn't exist I want qtp to not execute the next 3 keyword functions following it. Is there a way to do this? Thank you!
You could a global variable that records the number of keywords that should be skipped. When your element doesn't exist, you could set the skip count to 3. In your framework that reads each keyword, you could first check the current skip count. If it's 0, you execute the keyword normally. Otherwise, you decrease the skip count by 1 and exit without executing that keyword.
Can you not insert a conditional statement?
Therefore if the element exists, you can put the next 3 statements within the loop? Else, do nothing. Then have the code follow on as normal?
If you aren't comfortable in expert view, this shows how to do it in keyword view also:
