Software Testing Life Cycle

-
The software testing life cycle (STLC) identifies all testing activities and their relationship with other activities in the software development life cycle (SDLC).

Software testing should begin with the start of the software development life cycle.

The main activities of any software testing life cycle (various phases involved in testing) are:

1. Requirements analysis
2. Test planning, including test strategy
3. Test development and review
4. Test environment setup and maintenance (including test data preparation)
5. Test execution (static and dynamic)
6. Test reporting
7. Test result analysis (see "Software bug life cycle" on this website for details)
8. Defect retesting
9. Test automation
10. Test maintenance
11. Regression testing
12. Test closure


# QA activities that have an influence on the software testing life cycle: Software configuration management (change control)
# All QA defect prevention activities
Software testing activities and the software testing life cycle can depend on different system integration techniques used in software development.
The scope of testing and software testing life cycle activities may vary from customer to customer, product to product, and organization to organization depending on the methodology used.

Steps to Deploy the OFSAA application in WEBLOGIC server: ========================================================= 1) Generate the "context_name.ear" from the FIC_WEB area by executing the ./ant.sh 2) Create a folder by the name "applications" within the domain directory 3) Create a folder by the name "context_name.ear" within the newly created "applications" folder 4) Copy the context_name.ear file from the FIC_WEB folder to the newly create the "context_name.ear" folder created within the applciations folder 5) Explode the .ear file copied from the FIC_WEB area (jar -xvf context_name.ear), There are 2 files and 1 directory created after the .ear file is exploded as mentioned below a) context_name.war ---> file b) context_name.ear ---> file c) META_INF ---> folder 6) Delete the above files (.ear and .war files) 7) Create a new folder by the name "context_name.war" 8) Copy the context_name.war file from th

Client / Server Applications

-
What is: The client–server characteristic describes the relationship of cooperating programs in an application. The server component provides a function or service to one or many clients, which initiate requests for such services. Advantages: * In most cases, a client–server architecture enables the roles and responsibilities of a computing system to be distributed among several independent computers that are known to each other only through a network. This creates an additional advantage to this architecture: greater ease of maintenance. For example, it is possible to replace, repair, upgrade, or even relocate a server while its clients remain both unaware and unaffected by that change. * All data is stored on the servers, which generally have far greater security controls than most clients. Servers can better control access and resources, to guarantee that only those clients with the appropriate permissions may access and change data. * Since data storage is centralized, update
