Establishing value-driven QA largely depends on the right enforcement of software product testing life cycle. It totally pays off in achieving exceptional software quality and a 200% product success.
By understanding the STLC life cycle, you gain the ability to align testing efforts with overall project goals, optimize resource allocation, and make strategic decisions to ensure a seamless software development life cycle.
Let’s get started and take a deep-dive into the topic.
Testing is a fundamental part of any quality assurance (QA) and production process. And, the method that goes into conducting these tests for production often involves a series of organized steps that gets termed as ‘life cycle’.
Software products are no exception. It also runs through tests that are enforced using a definitive process comprising phases or qualifying stages. To get a clear perspective on this, you need to first ‘understand the definition of software testing’.
According to Techopedia, software testing is defined as a ‘set of processes aimed at investigating, evaluating, and ascertaining the completeness and quality of computer software. It’s a mechanism that helps ensure the compliance of a software product in relation with regulatory, business, technical, functional, and user requirements.’ In simple words, software testing includes:
Software testing can be automated and manual, and involves conducting thorough quality checks (bug detection, usability issues, security concerns, and more) that all aims to deliver the finest product to the end user that solves certain challenges.
Almost 5% of the businesses sign up for fully automated testing. Plus, 73% aim to achieve a 50:50 or 25:75 balance, and almost 14% aspire to eliminate manual testing.
Now, the above is all about software testing and its importance. But, ‘what is software testing life cycle?’
Well, software testing life cycle (or STLC) is precisely a systematic approach consisting of a series of well-defined stages that a software passes through during its development life cycle to ensure the quality, reliability, usability, and functionality of the digital product before its release to the end-users. It encompasses a series of well-defined phases with set ‘entry and exit’ criteria, each serving a specific purpose in the testing process.

During the software product development process, the STLC phases can be performed multiple times until the final output is deemed suitable for release and gets certified as 100% error-free.
The STLC approach emphasizes the significance of collaboration and effective communication between the development (or production) and testing teams for continuous improvement. With software testing life cycle, the defects or issues in a digital product gets identified early in the software development process that ultimately helps minimize risks, reduce costs, and enhance the overall output quality.
By enforcing a strategic QA mechanism in SDLC and employing end-to-end software testing services, enterprises can systematically and comprehensively implement quality checks for their digital product launches, ensuring they meet the expected standards and fulfill user needs..

Software testing life cycle involves a series of multi-step phases with each carrying certain ‘entry’ and ‘exit’ criteria that are carried out in sequence and in a systematic manner. The STLC steps are structured to identify not just the bugs but even the smallest glitches to avoid gaps and ensure top-notch quality assurance. The STLC stages usually consist of 7 stages. Let’s understand each of these phases step-by-step!
Analyzing the software requirements is the first and foremost step to start with the STLC process as it helps gain a clear understanding of the expected functionalities and performance. The test cases are then formulated to align with the set needs and outcome projections. The following workflows goes into this step of the STLC stages:
The set ‘entry’ and ‘exit’ criteria for the requirements analysis step includes:
Entry Criteria - Documented requirements of the software, defined acceptance criteria, and intended system architecture.
Exit Criteria – Client approved RTM (Requirement Traceability Matrix) and automation feasibility report.
Creating a comprehensive test strategy and plan is the next step to the STLC life cycle as it enables to set and define objectives, scope, resources, approach, timelines, and infrastructure. The following task list goes into this step:
The set ‘entry’ and ‘exit’ criteria for the test planning step includes:
Entry Criteria - Software requirements analysis document, RTM, and test automation feasibility report.
Exit Criteria - Approved test plan and strategy document including timelines and risk/cost analysis.
Designing detailed test cases and scripts is the third step to the STLC life cycle. This phase helps to lay the executional foundation, define parameters, set criteria's, and outline needs for running the test cases. It’s important that all the software requirements are 100% covered in this stage. The aspects that gets covered in this step of the testing life cycle include:
The set ‘entry’ and ‘exit’ criteria for the test design step includes:
Entry Criteria - Approved test strategy and test plan with complete timelines and risk/cost analysis.
Exit Criteria - Approved test cases/scripts with automation framework details and test data.
Not all tests can be performed on local machines. There are software products that needs to be validated for quality over a dedicated testing server. This STLC stage works for setting-up the test environment. There are wide range of software tools and hardware devices that are used for this sort of testing that includes Selenium, Katalon Studio, and TestComplete. The following workflow goes into this step of test environment setup:
The set ‘entry’ and ‘exit’ criteria for the test environment set-up phase includes:
Entry Criteria - System design and architecture layouts with environment set-up plan.
Exit Criteria - A fully functional test environment, approved test cases, and complete test data setup.
Now starts the actual execution. This is the step when the test cases are actually executed, defects are logged and tracked, and the software's behavior is validated against the expected results. Testers also conduct regression testing to ensure that the new changes or fixes do not introduce new issues. The following aspects are covered in this step:
The set ‘entry’ and ‘exit’ criteria for test execution involves:
Entry Criteria – Availability of all exit criteria from previous STLC phases including the RTM, test plan, test cases/scripts, established test environment, completed test data setup, and unit/integration test report.
Exit Criteria - All tests are performed as planned, defects logged and managed for closure, and results documented.
During the test execution phase, defects or bugs are identified, documented, and prioritized. They are then assigned to development teams for resolution. Defect tracking and management involve monitoring the progress of defect resolution and verifying fixes in subsequent test cycles. The aspects that are covered in this stage of the testing life cycle includes:
The test closure phase involves evaluating the overall test results, generating test reports, and analyzing the effectiveness of the testing process. Lessons learned from the testing experience are documented for future improvements, and the final sign-offs are obtained from clients/stakeholders. The test closure stage includes the following:
The set ‘entry’ and ‘exit’ criteria for test closure (the final STLC phase) includes:
Entry Criteria - Test results and logging from all previous phases with detailed defect logs.
Exit Criteria - Delivered and client approved test closure report.
