STLC and its 6 stages

STLC stand for Software Testing  Life Cycle.


What is STLC ?

STLC is the testing process which includes various phases or definite steps must be executed in order to ensure the quality of application/software.


Each Life cycle phase has its own significance and we will learn below importance of each.
STLC,Software Life Cycle,phases of software testing
6 phases of Software Testing Life Cycle.
  • Requirement Analysis : This phase is usually used for analysis and study the requirements. This phase helps to identify the scope of the testing. 
  • Test Planning : This is a practically first step in software testing. Its used to identify the activities and resources which helps to meet the testing objectives, hence this phase is known as test planning.
  • Test Case Development : This phase is used to write and analysis test cases/scenarios before actual testing is performed on software. These cases are created with respect to customer requirements or System requirement.
  • Environment and setup : Once test cases are ready and analysed, tester checks for compatibility of software and its environment before actually starts testing.
  • Test Execution : This is the stage where testers actually perform testing on prepared test cases during previous stages.
  • Test Cycle Closure : This phase concentrate on exit criteria and reporting. As testing is long & exhausting process and thus it needs to have an defined exit (to know when to stop testing).

Bug Life Cycle/Defect Life Cycle. Before moving on to Bug life cycle. Let learn little about Bugs .... What is Bug/Defect ? To simplify the term we can say a defect is an error or a bug, in the application which is created Bug/error/defects can be result of mistakes/fault/misjudgement etc. while designing or developing the application. What is Bug Life Cycle ? As the name suggest it is the journey of a bug covering the different states in its entire life. There are 5 most important stages in the life cycle of a defect, you can see below. ➤ When a tester executes the test cases, he might come across the test result which mismatches the expected result. This difference in the test result is referred as a Software Defect. ➤ These defects or differences are referred by different names in a different organization like issues, problem, bug or incidents. New Bug: When a defect/bug is discovered and reported for the first time. This is beginnin...

Software Testing - Definition, Types and Approach. What is Software Testing ? Its a process or a set of activities which is followed to evaluate the functionality and stability of the software. Finding Bugs with Software Testing Types of Software Testing :- Manual Testing - Its a process of testing where the software is tested manually to find the defects. Automation Testing  - The process of testing the software using an automation tool to find the defects  Types of Testing approaches :- White Box Testing  -It is based on applications internal code structure.Tester must have knowledge of script or coding language. White Box - Internal code testing Black Box Testing  -  It involves examining functionality of software without any knowledge of internal implementation and without seeing the source code. Tester need not require to have script of coding language. Black Box - Application level Testing
