 STLC - Software Testing Life Cycle
 “Software Testing Life Cycle(STLC) is the testing
process which is executed in systematic and
planned manner. In STLC process, different activities
are carried out to improve the quality of the product.”
 Software Testing Life Cycle refers to a
testing process which has specific steps to be
executed in a definite sequence to ensure that the
quality goals have been met.
 In STLC process, each activity is carried
out in a planned and systematic way. Each Phase
has different goals .

1. Requirement Analysis/Review
 This is a very important phase in STLC.
 In this phase the QA interacts with the Business
Analyst, System Analyst, Development Manager/Team
Lead, etc. or if required the QA may also interact with
Client to completely understand the requirements of the
system.
 During this phase the QA takes many important
decisions like what are the testing types & techniques to
be performed, feasibility for automation testing
implementation, etc.

Activities:-
 Identify types of tests to be performed.
 Gather details about testing priorities and
focus.
 Prepare RTM (Requirement Traceability
Matrix)
 Automation feasibility analysis .

2. Test Planning
 In this phase the QA/QA Lead/QA Manager
plans for the complete testing process.
 This Phase is also called Test Strategy phase.
Typically in this stage , a Senior QA manager will
determine effort and cost estimates for the project
and would prepare and finalize the Test Plan.
 This phase is very important as any small
mistake in this phase can result in major issues in
the project regarding time, money, efforts, etc.

Activities:-
 Preparation of test plan
 Test tool selection
 Test effort estimation
 Resource planning and determining
roles and responsibilities.
 Training requirement.

3. Test Designing
 Creation, Review & Update of Test Cases as
well as Test Scripts are done in this phase. The test
cases prepared by the QA team are reviewed and
approved.
 Test data may also be created in this phase by
the QA team if test environment is available to them.
 Activities:-
 Create test cases , automation scripts
 Review & baseline test cases

4. Test Environment Setup
 Test Environment is the actual
system/environment/setup where the testing team will
be testing the application. Test environment is
prepared by understanding the required system
architecture, software & hardware requirements, etc.
 Activities:-
 Understand the required architecture , environment
set-up and prepare hardware & software requirement
list for Test Environment.
 Setup test Environment and test data.

5. Test Execution
 The test cases which were prepared earlier
are executed in this phase. In this phase, the
testers test the websites. Different testing
techniques as well as methods are implemented
and executed on the software/application to break
the system and find bugs.
 Bugs are reported to the development team.
The development team resolves the bugs and the
system is retested to ensure that it is bug free and
ready to go live.

 Activities:-
 Execute tests as per plan.
 Document test results , and log defects for
failed cases.
 Map defects to test cases in RTM
 Retest the defect fixes
 Track the defects to closure

6. Test Closure
 When the testing team is confident that all the
reported bugs are resolved and the system is ready
according to the client’s requirements, the software
testing life cycle enters the last stage i.e.. Test
Closure stage.
 In this stage, evaluation is done for the
complete testing cycle, test closure reports are
prepared, proper analysis and documentation is
done for the major or critical bugs so that such
situations can be handled efficiently and effectively
in future projects, etc.

Activities:-
 Submitting STR (Software Test Result)
 Submitting Test Summary report , Test
Plan Document , Test Cases/Scripts etc.
 Sharing experiences with the team.
