What Is The Software Testing Life Cycle?

Posted 2 years ago in TECHNOLOGY.

Software testing is a critical stage of the software development cycle. This stage holds the entire software testing life cycle in itself. The process of software testing ensures the performance of software applications that it must run without any failures. The entire process must be a mu

What Is The Software Testing Life Cycle?

Similar to the process of creating software or solutions for business with a software development life cycle, software testing verifies and validates this software. Here we are detailing out all phases of the testing life cycle. It is not just a phase before release.

What Is The Software Testing Life Cycle?

The software testing life cycle designs a sequence of tasks to understand the state of a system and point out the scope of improvement. The STLC involves the following phases in the lifecycle.

  • Strategizing, 
  • Planning, 
  • Executing, and 
  • Completing test cycles.

Earlier, the QA testing was a small phase to test the product before the release to detect the functionality errors. With time, more complex software applications appeared that evolved the software testing processes. Today, software testers do not wait for the final product. To optimize the complex process of software development, companies are implementing software testing lifecycle phases before and during software development to maximize resources.  Some of the following powerful and most preferred strategies are:-

  • Test automation
  • Test-driven development
  • Crowdtesting
  • Shift-left testing
  • Shift-right testing

An effective STLC process gives more efficient, effective, and valid results than the traditional testing methodology.  It helps the organizations to make the change that boosts customer satisfaction and as a result better revenue growth.

What Are The 6 Phases Of The Software Testing Life Cycle?

Software testing brings confidence in the quality of a software and its performance in the industry. With STLC, the software testers are able to deliver an efficient solution by putting the entire code or application through the several series of tasks of test and trials. It validates the entire software from the ideation to the design and development of functionalities.  Each phase of the testing lifecycle helps in achieving the high-quality software release. Each stage of STLC has their own goals to detect the defects and optimize the test coverages.

The following phases belong to the software testing life cycle:

  1. Requirement analysis
  2. Test planning
  3. Test case design and development
  4. Test environment setup
  5. Test execution
  6. Test cycle closure

1. Requirement Analysis

A software testing starts straight from the software requirements that define the expectations from the software to improve the business value. Every software requirement looks for the following key elements

  • High level of the business expectation, 
  • System architecture needs to figure out what will be the design of features or final outcome. 
  • Detailed system requirements using which software developers build the product. 

These system requirements documents include the following 

  • functional specifications and 
  • non-functional specifications, 

Using both the testers plan the scenarios to test and validate.

Requirement analysis often includes brainstorming sessions, identifying vulnerabilities and pointing out the risk factors in the requirements, and prioritizing certain assessments. In case of doubts and confusions, the QA team connects with the engineering and business side with their concerns and plan an effective testing strategy.

2. Test Planning

This phase precisely plans the workflow. It takes insights and details during requirement analysis and turns them into documented format. Using this plan, the team determines the resources and efforts to determine the release. The final document of test planning explains how testing work will start to testers and other departments 

This planning document contains the following details

  • scope, 
  • objectives, 
  • types of functional 
  • non-functional tests (both automated and manual), 
  • and details for the test environments. 

Once everything is finalized for this phase, the test management establishes the roles and timelines of the work. 

3. Test Case Design and Development

After finalizing the test plan, testers can start writing and creating detailed test cases.In this STLC phase, the QA team details out the structured tests and test data that they need to run on the particular  module, including the test data for these tests. 

With Agile methodology, creating test cases also includes the  can be lTest cases might be recurring and time taking to maintain and update  both new and existing functionality. The same happened in the STLC processes.

4. Test Environment Setup

This is actually an ecosystem where the testing occurs. Testers get the access to report the bugs as well as the application architecture to support the product. Without these accessibilities, testers might not be able to perform the testing.

The testers establish the right set of parameters for the test environment. It includes the following elements

  • hardware, software, 
  • test data, 
  • frameworks, 
  • configurations and network. 

In this phase, the testers adjust the environment parameters depending upon the requirements of the software.

5. Test execution

This stage executes the full testing of the product. Here, testers execute all the test cases or as many as is possible within the allotted time. Our QA Outsourcing professionals and automated scripts help in running a number of functional and non-functional tests.

Here in the STLC, testers will identify and report the bugs in detail  in the bug tracking tool. These bugs occur from the test case execution and log the system’s performance compared to its requirements. As soon as developers fixes the bugs, testers often retest the product to make sure new defects don’t materialize.

6. Test cycle closure

The final stage in the  STLC is test cycle closure. Here, the entire QA team provides a detailed test closure report. It includes the sharing of a summary of the drawbacks to the other testers.

While closing the testing cycle, the testing team can check the deliverables,   This includes the details of the testing work, etc., such as the test strategy, test case documents, automated test scripts and test results and answer of What is QA Testing? After that, the entire team will complete and close incident reports, which detail unusual or unexpected behavior that the test team observes during testing.
