There are other six tests, which fall under special category. They are described below: 

Peak Load Test: It determines whether the system will handle the volume of activities that 
occur when the system is at the peak of its processing demand. For example, test the 
system by activating all terminals at the same time.


Storage Testing: It determines the capacity of the system to store transaction data on a disk 
or in other files. 

Performance Time Testing: it determines the length of time system used by the system to 
process transaction data. This test is conducted prior to implementation to determine how 
long it takes to get a response to an inquiry, make a backup copy of a file, or send a 
transmission and get a response. 

Recovery Testing: This testing determines the ability of user to recover data or re-start 
system after failure. For example, load backup copy of data and resume processing without 
data or integrity loss. 

Procedure Testing: It determines the clarity of documentation on operation and uses of 
system by having users do exactly what manuals request. For example, powering down 
system at the end of week or responding to paper-out light on printer. 

Human Factors Testing: It determines how users will use the system when processing data 
or preparing reports.

System Analysis: 
System analysis is a process of gathering and interpreting facts, diagnosing 
problems and the information about the Electricity Billing System to recommend 
improvements on the system. It is a problem solving activity that requires intensive 
communication between the system users and system developers. System analysis or 
study is an important phase of any system development process. The system is studied 
to the minutest detail and analyzed. The system analyst plays the role of the 
interrogator and dwells deep into the working of the present system. The system is 
viewed as a whole and the input to the system are identified. The outputs from the 
organizations are traced to the various processes. System analysis is concerned with 
becoming aware of the problem, identifying the relevant and decisional variables, 
analyzing and synthesizing the various factors and determining an optimal or at least a 
satisfactory solution or program of action. A detailed study of the process must be made 
by various techniques like interviews, questionnaires etc. The data collected by these 
sources must be scrutinized to arrive to a conclusion. The conclusion is an 
understanding of how the system functions. This system is called the existing system. 
Now the existing system is subjected to close study and problem areas are identified. 
The designer now functions as a problem solver and tries to sort out the difficulties that 
the enterprise faces. The solutions are given as proposals. The proposal is then 
weighed with the existing system analytically and the best one is selected. The proposal 
is presented to the user for an endorsement by the user. The proposal is reviewed on 
user request and suitable changes are made. This is loop that ends as soon as the user 
is satisfied with proposal. Preliminary study is the process of gathering and interpreting 
facts, using the information for further studies on the system. Preliminary study is 
problem solving activity that requires intensive communication between the system 
users and system developers. It does various feasibility studies. In these studies a 
rough figure of the system activities can be obtained, from which the decision about the 
strategies to be followed for effective system study and analysis can be taken.
