The last decade has seen an overwhelming evolution of the Software Testing industry giving way to greener pastures. It is important to ensure the effective performance of software application and Software Testing is required to ensure that the application runs without any failures. This blog on Software Testing life cycle will provide detailed knowledge about all the steps involved in testing in the following sequence :
Software Testing is a process of evaluating the functionality of a software application to find any software bugs. It checks whether the developed software met the specified requirements and identifies any defect in the software in order to produce a quality product.
Now that we know what is software testing, let’s move ahead with our software testing life cycle blog and see why do we need testing.
The importance of software testing is imperative. Software Testing is important because of the following reasons:
Now that we know what is software testing and why it is important, let’s get into the details of the software testing life cycle and know more about the different phases of testing.
Software Testing Life Cycle (STLC) defines a series of activities conducted to perform Software Testing. It identifies what test activities to carry out and when to accomplish those test activities. In the STLC process, each activity is carried out in a planned and systematic way and each phase has different goals and deliverables.
Now let’s move ahead and have a look at the different phases of software testing life cycle in detail.
Requirement Analysis is the first step involved in Software testing life cycle. In this step, Quality Assurance (QA) team understands the requirement in terms of what we will testing & figure out the testable requirements. During this phase, test team studies the requirements from a testing point of view to identify the testable requirements.The QA team may interact with various stakeholders such as client, business analyst, technical leads, system architects etc. to understand the requirements in detail.
The different types of Requirements include :
Business Requirements – They are high-level requirements that are taken from the business case from the projects.
Architectural & Design Requirements – These requirements are more detailed than business requirements. It determines the overall design required to implement the business requirement.
System & Integration Requirements – It is detailed description of each and every requirement. It can be in form of user stories which is really describing everyday business language. The requirements are in abundant details so that developers can begin coding.
The following documents are required:
Test Planning is the most important phase of Software testing life cycle where all testing strategy is defined. This phase is also called as Test Strategy phase. In this phase, the Test Manager is involved to determine the effort and cost estimates for the entire project. It defines the objective & scope of the project.
The commonly used Testing types are :
Test plan is one of the most important steps in software testing life cycle. The steps involved in writing a test plan include :
The Test case development begins once the test planning phase is completed. This is the phase of STLC where testing team notes the detailed test cases. Along with test cases, testing team also prepares the test data for testing. Once the test cases are ready then these test cases are reviewed by peer members or QA lead.
Setting up the test environment is vital part of the Software Testing Life Cycle. A testing environment is a setup of software and hardware for the testing teams to execute test cases. It supports test execution with hardware, software and network configured.
The next phase in Software Testing Life Cycle is Test Execution. Test execution is the process of executing the code and comparing the expected and actual results. When test execution begins, the test analysts start executing the test scripts based on test strategy allowed in the project.
The final phase of the Software Testing Life Cycle is Test Cycle Closure. It involves calling out the testing team member meeting & evaluating cycle completion criteria based on Test coverage, Quality, Cost, Time, Critical Business Objectives, and Software.
A test closure report by the test lead is published after accomplishing the exit criteria and finishing the testing phase. It follows a standard format such as :
Stages of Test Closure :
The process of test closure is implemented with the assistance of six important stages such as –
Let’s now move ahead with this article and understand the difference between SDLC and STLC.

Now with this, we come to an end to this “Software Testing Life Cycle” blog. I hope you guys enjoyed this article and understood what is software testing and the different Types of Software testing.
