Briefly Explained Software Testing Lifecycle. software testing life cycle modelsSoftware testing life cycle is the testing procedure which is performed in efficient and arranged way. In Software testing life cycle models, diverse activities are completed to enhance the quality of software product.

In simple words, Software Testing Life Cycle (STLC) is characterized as a set of activities led to perform Software Testing.

There are various stages of software testing life cycle, which performed methodologically for assisting or certifying your software product.

Each of these stages has a specific Entry and Exit criteria in software testing life cycle as well as Activities and Deliverables connected with it.


Explain software testing life cycle’s Entry and Exit criteria:

Entry Criteria: Entry Criteria gives the essential things that must be finished before testing can start.

Exit Criteria: Exit Criteria characterizes the things that must be finished before testing can be closed

You have Entry and Exit Criteria for all levels in the Software Testing Life Cycle models.


What phases make up the software testing life cycle models?

Software testing life cycle phases may vary, yet mainly, they include arranging, planning, leading, and revealing. Let’s investigate diverse parts of the software testing cycle.

Requirement Phase:

The Requirement Phase of testing life cycle model in software testing deals with the break down and study of requirements. Have meetings to generate new ideas with different teams and attempt to see if the necessities are testable or not. This phase distinguishes the extent of the testing. If any element isn’t testable, communicate it during this stage with the goal that the reduction procedure can be arranged.

Test Planning:

What to test, how the test should be done, and who will test it… these are the things decided at the test planning phase. Once the requirements have been checked on, it’s a great opportunity to design the testing project at an abnormal state. A test plan record is made during this stage. This stage gets everybody on the same page from far as how the testing project will be drawn nearer.

Building up the Test Case:

One of the critical phase of the testing life cycle in software testing is building up the test cases. This incorporates working out a well ordered method on how the test must be executed, the normal outcomes, the actual outcomes, and if the test was a pass or a fail. For instance, to test the button for adding things to a shopping basket, the test case could look something like this:

Stage 1: Select a thing.

Stage 2: Click the button ‘Add thing to shopping basket.’

Stage 3: Check to watch out whether the right thing and right amount was added to the shopping basket.

Stage 4: If the thing was added effectively, the test was a pass; else, it was a fail.

Test Environment:

The test environment is the setup of software testing life cycle models as well as equipment on which the testing team is to execute the tests. Without the test environment prepared to go, you will hit hindrances. Ensure any important test data is gone into the framework and prepared to be utilized. It’s normal for this stage to occur close by the test case advancement stage.

Test Execution:

Since the tests are prepared to go and the environment is setup, it’s an ideal opportunity to run the tests. Utilizing the test cases, the tester executes each test, contrasting the normal outcomes with the real consequences of each test and stamping it as skip/fail/pass. In any case the test fail, the tester should document what really occurred during the test. This stage as well includes the tester logging bugs in the assigned bug life cycle in software testing cycle.

Test Reporting:

When every one of the tests cases are ran, the test supervisor must assure all required testing have been finished. This includes an investigation of defect life cycle in software testing and different measurements, for example, what number of skipped/passed/failed test cases. This last stage in the software testing life cycle models may also incorporate a review on the testing procedure/project. This enables the team to learn and enhance for future testing projects.


Software testing life cycle is a standard methodology isolated into various phases, pursued by the QA Team to finish all testing action. I think I have labeled all the major part of Software Testing Life Cycle models. So, that our clients get to know our testers skills and intelligence in brief.
