High Level Design (HLD) and Low Level Design(LLD) Documents

High Level Design Document: HLD is the design document convert the user requirement into the detailed design of Application. In HLD document, application is divides into different different modules. After that each modules divides into micro modules and then each micro modules take at a time to work over it.

This document include the System Architecture, Database Architecture, Structure of the System, Application Architecture, Application flow, Technology Architecture
and the Security Architecture.
This document very useful for the developer to understand the flow of the application. In this phase entry criteria is the Requirement Document and the HLD is the exit criteria.

Low Level Design Document: LLD is the design document prepared when the modules design of HLD will be broken into the micro level. LLD document contains the date structure required software architecture, source code and performance algorithm.

LLD is the stage where actual software component are designed. It also contains the detailed functional logic of the software, Database Table with element with type and size, dependency, input and output between interfaces.

Entry Level is HLD documents, and the Unit Test plan is the exit level.

What is API?

In general way, API (Application Programming Interface) is the intermediate software which is useful for two applications to communicate. API is the tool which is used for interaction of two applications. If developer developing any software which have multiple blocks (Modules) than developer use APIs to put them together.

How to Put Load on a Script in JMeter

In last post we discussed about how to record a test script and Firefox settings to run the script. In this post we will discuss about how the Thread Group will work, how can we put n number of users to perform load testing, In JMeter by using Thread Group, we can create virtual users. Thread Group is a set of thread which work in same scenario. There are multiple thread group are available which is use to configure how the virtual users interest with the application, How much load maintain and till how much time load maintain.

Quality Assurance and Quality Control

Quality Assurance (QA) and Quality Control(QC) both seems similar for people but they are totally different in Product development cycle. QA and QC both have absolute different role. Generally it is assume that both can interchange their role when needed but this is totally wrong, both role are totally different and not changeable.
