Towards reusable thread-group code

[AntonioSun]

I know the DSL groovy-jmeter provides currently is focus on wrapping over JMeter ones, but am hoping it can go one level up to achieve the following --

In our testing, we have standalone tests that focus on one specific area, and mixed load test that put them all together. The current situation is, both in groovy-jmeter and JMeter, it's rather difficult to reuse the thread-group code for both cases, as the load design/requirement is very different. As the result, we have to break the following natually grouped code into two parts, the group line and its content:

        // define group of 1000 users with ramp up period 300 seconds
        group(users: 1000, rampUp: 300) {
            // add cookie manager for HTTP requests
. . .

Such break-up doesn't feel natual. the group line and its content are seprated.

If somehow we can design a DSL that allows the insert code file can have the group line within it, and pass every prameter that group can accept to it, it'll looks ideal, ..., but, having written it all out, I'm now wondering if it is worth the trouble 😊😊...

Hi, it seems valid request. So as understand you what you would like to have is something like:

// test.groovy

start {
   // simple case
   insert 'fragments/group.groovy', properties: [ users: 1, rampUp: 10]

   // load test
   insert 'fragments/group.groovy', properties: [users: 1000, rampUp: 300]
}

// fragments/group.groovy
fragment {
    group users: users, rampUp: rampUp, {
         cookies()
         simple {
               http 'GET sample.com'
         }
    }
}

This should be quite doable but you can try to do it in some other way e.g.

// test.groovy

@GrabConfig(systemClassLoader=true)                                             
@Grab('net.simonix.scripts:groovy-jmeter')                                     
                                                                               
@groovy.transform.BaseScript net.simonix.dsl.jmeter.TestScript script          
                                                                               

start {
    plan 'Test plan', {
        group users: 1, rampUp: 10, {
            insert 'fragments/group.groovy'
        }
        
        group users: 1000, rampUp: 300, {
            insert 'fragments/group.groovy'
        }    
    }
}

// fragments/group.groovy
fragment {
    cookies()
    simple {
         http 'GET sample.com'
    }
}

Hope it helps

Yes, this is exactly what I'm doing now, which I can continue doing.

Your proposed solution looks fabulous, even better than I had imagined. Looking forward to it!

Hi, with this #126 the new variables property added to insert keyword so you can pass variables to fragment.

👏👏👏🎉🎉🎉
Time to cut a new release maybe?

[smicyk]

Done. v0.22.0

Should be available in maven repos in 1-2 days.
