===================================================================
Making a TestBean Plugin For JMeter
This component will be a CSV file reading element that will let users easily vary
their input
data using csv files.
1. Pick a package and make three files:
- [ComponentName].java (CSVDataSet.java)
- [ComponentName]BeanInfo.java (CSVDataSetBeanInfo.java)
- [ComponentName]Resources.properties (CSVDataSetResources.properties)
2. CSVDataSet.java must implement the TestBean interface. In addition, it will
extend
AbstractTestElement, and implement PreProcessor, TestListener and
LoopIterationListener.
- TestBean is a marker interface, so there are no methods to implement.
3. CSVDataSetBeanInfo.java should extend org.apache.jmeter.testbeans.BeanInfoSupport
- create a zero-parameter constructor in which we call super(CSVDataSet.class);
- we'll come back to this.
4. CSVDataSetResources.properties - blank for now
5. Implement your special logic for you plugin class.
- The CSVDataSet will read a single CSV file and will store the values it
finds into
JMeter's running context. The user will define the file, define the variable
names for
each "column". The CSVDataSet will open the file when the test starts, and
close it
when the test ends (thus we implement TestListener). The CSVDataSet will
update the
contents of the variables for every test thread, and for each iteration
through its
parent controller, by reading new lines in the file. When we reach the end of
the file,
we'll start again at the beginning.
- When implementing a TestBean, pay careful attention to your properties.
These
properties will become the basis of a gui form by which users will configure
the CSVDataSet
element.
- Your element will be cloned by JMeter when the test starts. Each thread
will get it's own instance. However, you will
have a chance to control how the cloning is done - we'll be taking advantage
of this for CSVDataSet (since we don't want to open the file X number of times from X
number of threads).
a. Properties: filename, variableNames. With public getters and setters.
- filename is self-explanatory, it will hold the name of the CSV file
we'll read
- variableNames is a String which will allow a user to enter the names
of
the variables we'll assign values to. Why a String? Why not a
Collection - surely
users will need to enter multiple (and unknown number) variable names?
True, but
if we used a List or Collection, we'd have to write a gui component to
handle
collections, and I just want to do this quickly. Instead, we'll let
users input
comma-delimited list of variable names.
