3. Generating DSL Methods

Summary

If you need additional JMeter Elements not already included in the gem, you can generate them with the included rake task.

1. Add the rake task to your Rakefile

# Rakefile
require 'jmeter_perf'

spec = Gem::Specification.find_by_name 'jmeter_perf'
rakefile = "#{spec.gem_dir}/lib/my_gem/Rakefile"
load rakefile

2. Save your IDL/Test Plan and generate additional DSL methods

<!--idl.xml-->
<?xml version="1.0" encoding="UTF-8"?>
<jmeterTestPlan version="1.2" properties="2.9" jmeter="3.0 r1743807">
  <hashTree>
    <TestPlan guiclass="TestPlanGui" testclass="TestPlan" testname="Test Plan" enabled="true">
    <hashTree>
      <!--NOTE the "testname" will be used--> 
      <CounterConfig guiclass="CounterConfigGui" testclass="CounterConfig" testname="Counter" enabled="true">
        <stringProp name="CounterConfig.start"></stringProp>
        <stringProp name="CounterConfig.end"></stringProp>
        <stringProp name="CounterConfig.incr"></stringProp>
        <stringProp name="CounterConfig.name"></stringProp>
        <stringProp name="CounterConfig.format"></stringProp>
        <boolProp name="CounterConfig.per_user">true</boolProp>
        <boolProp name="CounterConfig.reset_on_tg_iteration">true</boolProp>
      </CounterConfig>
    </hashTree>
  </hashTree>
</jmeterTestPlan>

$ bundle exec rake jmeter_perf:dsl_generate["path/to/dsl/directory/","path/to/idl.xml"]

This will generate files pertaining to your JMeter Element. You can then use the standard DSL to run them.

Example:

# Some test
JmeterPerf.test do
  counter name: 'My Counter', start: 1, end: 10, increment: 1, per_user: true do
    http_sampler name: 'Counter Request', url: 'http://example.com/counter'
  end
end
