Key Phases of the Software Testing Lifecycle

Software testing is a crucial process to remove errors and bugs from the application. Different portals, dashboards, features, and functionalities are integrated into the software, complicating the testing process. Thus, most software testing services companies, professionals, or quality analysts use different tests to verify the complete software efficiently. These strategies consist of several key phases that help perform the systematic testing. The whole process is called the System Testing Life Cycle or STLC. In this blog, we will discuss the Key Phases of the Software Testing LifeCycle.

What Is the Software Testing Life Cycle?

Before jumping directly to the phases of the software testing lifecycle, it is better to have a keen understanding of the process first. So, this is a series of tasks that helps conduct several consecutive software tests and ensures that the software’s quality standards are met once the testing is completed. Different phases complete the process systematically, where some phases are conducted only once in the life cycle while others might be performed more than once. Software testing companies keep the testing process going until the best versions of the software have been achieved and the digital product is ready to launch and offer to the target audience. 

6 Phases of Software Testing Life Cycle (STLC)

The complete process of the Software Testing Life Cycle consists of major 6 stages. From identifying the testing requirement to the closure of the testing process, hundreds of practices help achieve the finest version of the software. Let’s have a glance over the different key phases of the Software Testing Life Cycle- 

Phase 1: Requirement Analysis 

Like the development process, the testing process also starts with a quality analyst understanding the requirements of the software. For the same, testing professionals often collaborate with developers, clients, and relevant key stakeholders. The requirements in this phase can be functional as well as non-functional. The requirement analysis begins with document requirements, intended product architecture, and acceptance criteria. The execution of the process can be observed with an approved requirement traceability matrix and automation feasibility report. 

Phase 2: Complete Planning for the Testing 

As the terminology suggests, this step outlines the planning and milestones that will be achieved throughout the process. At the same time, information like resources required, team allocation, task allocation, and tools required, along with roles and responsibilities are diluted to the team. The core aim of this phase is to conduct the risk and cost analysis to estimate and commit to the deadline and budget to respective stakeholders. The phase begins with requirement analysis, automation feasibility report, and RTM. The phase is completed with an approved test plan that consists of risk/cost analysis. 

Phase 3: Test Case Development 

Test cases are developed in the 3rd phase of this lifecycle. Each case carries information about test inputs, execution conditions, procedures, and anticipated results. The test cases must be adaptable, efficient, and transparent to perform the perfect testing. After completing all the test cases, the quality analyst team ensures the test coverage is 100%. Scripts are also created in this step when the team opts for automated testing. Phase 3 starts with an approved test plan that includes risk/cost analysis and ends with approved test cases and automation scripts. 

Phase 4: Setting Up the Test Environment 

This is the 4th step of the Software Testing Life Cycle where testing environments are configured and then deployed. A variety of testing tools like Selenium, TestComplete, Katalon Studio, and Appium are included in this phase which helps set up the testing environment. Moreover, the process also consists of setting up the servers for testing. Smoke tests are conducted after the environment deployment that identify whether the test environment is working according to expectations with the intended functionalities. System design, and project architecture definition are the beginning of this phase while a fully-functioning test environment with approved test cases is the completion of this phase. 

Phase 5: Test Execution 

Feature testing is the foremost process of this phase which is conducted when the environment setup is complete. This action is performed using the established cases. The actual results are analysed in this step which are then compared to the expected results. The overall report of comparison between expected and actual results is prepared and sent to the development team. Approved test cases begin this phase, while documentation of results gives the full stop to this 5th step. 

Phase 6: Closure of Test Cycle 

This is the final stage of the Software Testing Life Cycle. The test result report is prepared, which summarizes the complete testing process and provides a comparison of expected results and actual results. Different information and comparisons like objectives met, total cost, time taken for testing, test coverage, bugs found and resolved, defect identification, etc. are included in this step. Reporting the test result to the development team is the start of this final stage. On the other hand, delivering and approving test closure reports is the final practice of the process. 

Common Tasks of Software Testing Life Cycle Process

Having gone through the complete testing process, it is time to revise the core tasks that complete the process. These common tasks make it easier for the stakeholders to understand the complete testing process and ensure that efficient testing has been carried out. So, here are the core tasks of the STLC process- 

  • Stakeholder and client requirement analysis 
  • Creating the traceability matrix (a document that portrays the project completion by comparing the feature requirements)
  • Testing types and techniques identification for different features 
  • Brainstorming for automation of the testing process 
  • Identifying the environmental information 

Final Words 

So, the testing process is a crucial practice in the software development journey that helps to achieve the best version of the software and enhance the user experience. However, it is also important to understand the testing process and the key milestones achieved throughout it. Observe all the above-defined steps in your testing process to ensure that your software has been tested optimally and doesn’t carry any bugs or issues.
