STLC consists of six (generic) phases:
• Test Planning,
• Test Analysis,
• Test Design,
• Construction and verification,
• Testing Cycles,
• Final Testing and Implementation and
• Post Implementation.
•Test Planning
This is the phase where Project Manager has to decide what
things need to be tested, do I have the appropriate budget
etc. Naturally proper planning at this stage would greatly
reduce the risk of low quality software. This planning will
be an ongoing process with no end point.
Activities at this stage would include preparation of high
level test plan-(according to IEEE test plan template The
Software Test Plan (STP) is designed to prescribe the
scope, approach, resources, and schedule of all testing
activities. The plan must identify the items to be tested,
the features to be tested, the types of testing to be
performed, the personnel responsible for testing, the
resources and schedule required to complete testing, and
the risks associated with the plan.). Almost all of the
activities done during this stage are included in this
software test plan and revolve around a test plan.
•Test Analysis
Once test plan is made and decided upon, next step is to
delve little more into the project and decide what types of
testing should be carried out at different stages of SDLC,
do we need or plan to automate, if yes then when the
appropriate time to automate is, what type of specific
documentation I need for testing.
Proper and regular meetings should be held between testing
teams, project managers, development teams, Business
Analysts to check the progress of things which will give a
fair idea of the movement of the project and ensure the
completeness of the test plan created in the planning
phase, which will further help in enhancing the right
testing strategy created earlier. We will start creating
test case formats and test cases itself. In this stage we
need to develop Functional validation matrix based on
Business Requirements to ensure that all system
requirements are covered by one or more test cases,
identify which test cases to automate, begin review of
documentation, i.e. Functional Design, Business
Requirements, Product Specifications, Product Externals
etc. We also have to define areas for Stress and
Performance testing.
•Test Design
Test plans and cases which were developed in the analysis
phase are revised. Functional validation matrix is also
revised and finalized. In this stage risk assessment
criteria is developed. If you have thought of automation
then you have to select which test cases to automate and
begin writing scripts for them. Test data is prepared.
Standards for unit testing and pass / fail criteria are
defined here. Schedule for testing is revised (if
necessary) & finalized and test environment is prepared.
•Construction and verification
In this phase we have to complete all the test plans, test
cases, complete the scripting of the automated test cases,
Stress and Performance testing plans needs to be completed.
We have to support the development team in their unit
testing phase. And obviously bug reporting would be done as
when the bugs are found. Integration tests are performed
and errors (if any) are reported.
•Testing Cycles
In this phase we have to complete testing cycles until test
cases are executed without errors or a predefined condition
is reached. Run test cases --> Report Bugs --> revise test
cases (if needed) --> add new test cases (if needed) -->
bug fixing --> retesting (test cycle 2, test cycle 3….).
•Final Testing and Implementation
In this we have to execute remaining stress and performance
test cases, documentation for testing is completed /
updated, provide and complete different matrices for
testing. Acceptance, load and recovery testing will also be
conducted and the application needs to be verified under
production conditions.
Currently role is performing Specialty based testing (i.e.)
FUNCTIONALITY TESTING.
•Post Implementation
In this phase, the testing process is evaluated and lessons
learnt from that testing process are documented. Line of
attack to prevent similar problems in future projects is
identified. Create plans to improve the processes. The
recording of new errors and enhancements is an ongoing
process. Cleaning up of test environment is done and test
machines are restored to base lines in this stage.
