Software Testing : Introduction

Software Testing is a process to detect and remove errors from the software product.
The purpose of software testing is to show that the program performs its internal functionalities correctly.
Software Testing is the process to meet specifications of a software in order to improve quality and reduce risk in the software.
It is the procedure used to execute a program with intent of finding errors.

Bugs: When an error is found during the development phase and is accepted by developers is called as Bug.
Defects: When the actual result deviates from the expected results and is found by testers then, it is called as defect in a software product.
Error: When the functionality of the software products gets changed i.e. mistake made while coding are called as Errors. For example: Wrong syntax and infinite loops can cause errors.
Faults: A wrong step or process which can cause a software product to behave inappropriately is called as Fault.
Failures: When the faults in a software product gets executed, they turns into Failures.

Test cases are well maintained and well documented procedure designs that can be used to test the functionality and features of any software product.
Finding errors in the software program is the main objective of designing test cases.
Test cases contains the identity number in order to check for the behavior of software program.
There are five major components of test case strategy. These are:
1. Test Case Id:Identity number for each test cases.
2. Purpose:The motive of generating test cases.
3. Precondition:The conditions that are implied on the input in order to generate desired outputs.
4. Inputs.
5. Outputs.

When multiple test cases are combined together, it generates a test suit.
Each test suit can have multiple test cases and a test case can be added to any of the test suit as per requirement.
Test suits contains both functional as well as non-functional testing.

Software Testing : Test Suit

A testing oracle is a structural technique that can be used for checking the validity of test cases i.e. to check whether the test cases has passed or not.
This primary goal is achieved by operating these testing oracle separately from the system testing.
The testing oracle suit contains:
1. Oracle Load Testing
2. Oracle Test Manage.
3. Oracle Functional Testing.

When the whole software product is examined for its compliance and standardization, it is known as software audits.
The software audits are done in order to generate action plans along with identification of risk related to projects.
Software auditing process consists of three components. These are:
1. Planning.
2. Auditing.
3. Follow-Up.
