Not 10, but 6 things about jMeter

I list down some "good to know" things about jMeter. Hope it helps you while considering the jMeter scripts design, development and execution.
  1.  Its open source Java tool for functional and load testing.
  2. Can be "extended" to create new sampler, controller etc.
  3. Module Controller - If your scripts are going heavy and you found many copy-paste steps; in that case just create a module of those steps. Module is like a function in programming.
  4. Include controller - Some modules are global and can be used in many scripts, in that case just include that JMX into your main JMX, like you include JSP tag.
  5. Parameterized Controller - Third party controller which enable us to pass various runtime parameters to sample. Usually sits on top of module controller. http://code.google.com/p/jmeter-plugins/
  6. jMeter scripts can be executed from ANT, it help in automating the daily execution of scripts. (Can be triggered from nightly build process from your CI server): http://www.programmerplanet.org/pages/projects/jmeter-ant-task.php The same site also got one XSLT for transforming your JTL (jMeter log of sript execution) to HTML report. 
I''ll update this list as I explore jMeter more!

INTO OUTFILE query, How to modify & output null values ?

I tried one query (originally asked at JR) on MySQL which export the table data into a file, with a comma delimited field. The query is straight forward and replace the null column value by "\N" character, but when I want to replace that "\N" value by some other character like "0" or simple empty field like " ", its gets little tricky. Here is the base query SELECT Id, name, age FROM student INTO OUTFILE 'c:/result.txt' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'; And it outputs like, 1, "sagar", 23 2, "anant", 24 Now suppose some 'name' fields are null, then it outputs like 1, "sagar", 23 2, \N, 24 Now to obtain my desired results, which replace this null (\N) values by empty string like, "", I tried out two solutions --1. Using CASE statement SELECT Id, CASE WHEN name IS NULL THEN '' ELSE name END AS NewName, age FROM s

Java Generics: Why I get "name clash" exception when I override methods with different "type" parameter ?

import java.util.*; class Parent { void foo(List<String> list) { System.out.println("parent"); } } class Child extends Parent { void foo(List<Integer> list) { System.out.println("child"); } } When you compile this code you will get an error like Parent.java:7: name clash: foo(java.util.List<java.lang.Integer>) in Child and foo(java.util.List<java.lang.String>) in Parent have the same erasure, yet neither overrides the other class Child extends Parent { ^ 1 error This "name clash" error thrown because of "type erasure" thing when "generics" code gets complied. Let’s see how, When we complied any generics code, the compiler removes the type from the code and treat it as a simple pre Java 1.5 code, like, in our case, compiler saw something like this, import java.util.*; class Parent { void foo(List list) { // oops, <String> get erased. System.out.println("parent"); } } class Child extend
