Software Testing Life Cycle

STLC(Software Testing Life Cycle):-

Test Planning:

Define objectives of testing and the specification of test activities in order to meet the objectives and targets.

Test Analysis and Design:

General testing objectives are transformed into tangible test scenarios and test cases. The major tasks of this phase of test lifecycle are as follows:

-Reviewing the test basis

-Evaluating testability of the test basis and test objects

-Identifying and prioritizing test conditions based on analysis of test items, the specification, behavior and structure of the software.

-Designing the test environment set-up and identifying any required infrastructure and tools

-Creating bi-directional traceability between test basis and test cases.

Test Execution:

-Finalizing, executing and prioritising test cases

-Developing and prioritising test procedures, creating test data and preparing test harnesses 

-Writing automated test scripts (if automation testing is planned)

-Creating test suites from the test procedures for efficient test execution

-Verifying the test environment has been set up correctly.

The major tasks involved in this phase are as follows:

-Verifying and updating bi-directional traceability between test basis and test cases.

-Executing test procedures either manually or by using test execution according to the planned sequence.

-Logging the outcome of test execution and recording the versions of the software under test, test tools and testware

-Comparing actual results with expected results

-Reporting discrepancies as incidents and analysing them in order to establish their cause.

-Repeating test activities as a result of action taken for each discrepancy, re-execution of a test that previously failed in order to confirm a fix(Re test)

-Execution of a corrected test in order to ensure that defects have not been introduced in unchanged areas of the software as a result of defect fixing(Regression test).

Test Closure: 

Test Closure activities include the following major tasks:

-Planned deliverables have been delivered

-Creation of test summary report

-Handover test ware to maintenance team.
