While working on TestAutomation, we introduced spring IoC and had a look at PageObjects, there are totally stateless so why dont' let just make 'em singleton?

IMO it will burden unecessary memory requirements on JVM, but given today's machine where we usaually have many GB of RAM I am not sure how significant can be the impact.

Let's say we have 100 pageObjects, if 20 instance create a load of 1 MB, 100 will create 5 MB.

If you are using singleton for before the test spring has to load the 10MB, although it will be one time cost due to context-caching

As I said I would always prefer non-static over static method.

• I am big fan of pure/stateless function,there easy to understand and test, Static method as pure function i.e stateless are not bad but the real problem is to maintain the decipline to keep the 'em stateless.
• Testablitly: Class B has static method B.foo(), now consider

class A  {

	public void bar() {
		//some important code
		B.foo();// How mock foo bahaviour? may be fiddling classloader with PowerMock but that comes with some bagage too
 //some more important code
