The Software Testing Life Cycle(STLC) is a succession of explicit activities performed during the testing system to guarantee that the product quality goals are met. The STLC incorporates both confirmation and approval. 

Unlike mainstream thinking, programming testing in web development is not simply a different movement. It comprises a progression of strategic exercises to assist with guaranteeing your product item.

The STLC is an excellent technique straightforwardly connected with and part of the Software Development Life Cycle (SDLC), which like this, is a structure with six center standards:

  • Requirement analysis;
  • Planning;
  • Designing and planning;
  • Software development;
  • Testing;
  • Organization.

The SDLC is a cycle where activities at each stage are reflected in the subsequent stages. The STLC has its stages and most intently meets with the SDLC at the fifth stage, which I will depict below.

Features of STLC

  • STLC is an essential piece of the Software Development Life Cycle (SDLC); however, STLC comprises just the testing stages.
  • STLC begins when prerequisites are characterized or partners share programming necessity records.
  • STLC yields a bit-by-bit interaction to guarantee quality programming.
  • In the underlying phases of STLC, while the product item or the application is being created, the testing group examines and characterizes the extent of testing, section and leave models, and the experiments. It assists with lessening the test process duration and upgrading the item quality.
  • When the advancement stage is finished, the trying group is prepared with experiments, and execution begins—this aids in tracking down bugs in the beginning stage.

What to Involve the STLC For?

By realizing that the STLC is a bunch of measures, we can expect that it incorporates different stages, like preparation, control, execution, normalization, etc. This leads us to the way that the STLC is required not exclusively to test the created item but additionally for the accompanying:

  • Eliminating its weaknesses during the earliest and most beneficial progressive phase;
  • Expanding the quality and straightforwardness of the improvement cycle;
  • Boosting command over the nature of the item being created at all test phases of the SDLC;
  • Impacting the use of Agile, Scrum, SAFe, and so on.;
  • Conveying a quality item not exclusively to the Client but additionally to the Users.

The Job of the STLC in the SDLC

The job of the STLC in the SDLC


As referenced before, the Software Testing Life Cycle and the Software Development Life Cycle are firmly connected, yet they all the while seeking after various undertakings of a similar objective, specifically:

  • Gathering the prerequisites in the ideal structure and fostering the pronounced usefulness (concerning the SDLC);
  • I am breaking down prerequisites, helping the Client and the improvement group, and affirming the nature of the executed usefulness (concerning the STLC).

The general objective is client fulfillment and accomplishing the most elevated conceivable score at the Verification and Validation stages.

The SDLC and the STLC lines move in equal amounts for the vast majority of the undertaking however start to unite quickly during the product advancement stage with profound synchronization during the SDLC Test stage. 

This chart is pertinent to a wide range of kinds of undertakings, not simply enormous or free ones, and will continue as before for the execution of an assignment inside a venture and opposite for a task with a colossal number of cycles (yet for this situation, the lines will wander and meet on a more regular basis).

What are the STLС stages?

What are the STLС stages


The STLC has a few interconnected stages and is, by and large, the same as the SDLC framework. These stages are successive and are called:

  • Requirement Analysis;
  • Test Planning;
  • Test case Development;
  • Test Environment Setup;
  • Test Execution;
  • Test Cycle Closure.

How about we look into every one of them?

1. Requirement Analysis

Requirement Analysis is perhaps the main stage since this is the point at which you can fix project blemishes totally for nothing. The Requirement Analysis stage additionally distinguishes the standard requirement for robotized testing and permits making financial computations of work costs in light of the task assessment. 

This is also when the Entry and Exit Criteria are examined and recorded.

2. Test Planning

At this stage, a test plan is shaped. This concretizes all periods of the actual testing, timing, members, and obligations. Thus, we get information on:

  • the members and their parts in testing;
  • the critical testing tools;
  • the important test climate.

3. Test Case Development

Test case development suggests utilizing manual and computerized testing to fully include the product's usefulness, with the cycle being founded on the prerequisites set up in advance. 

As a general rule, the experiments for robotized testing are composed independently since the cases for manual testing are portrayed as cheat sheets.

4. Test Environment Setup

The test plan clarifies which test climate ought to be utilized. At this STLC stage, working frameworks and virtual machines are arranged, trying apparatuses like Selenium, Katalon Studio, and the undertaking's test climate and data sets are conveyed. 

We additionally make solicitations to DevOps and Admins if help is required.

5. Test Execution

Tests are performed given instant test documentation and an accurately arranged test climate. All experimental outcomes are kept in the Test Management System. 

Adversely breezed through assessments, where the actual outcome contrasts from the one expected, are recorded as blunders and moved to the improvement group for modification with ensuing reverifying after remedy.

6. Test Cycle Closure

The last period of the STLC is the last age of the Client's testing reports. These should incorporate the time spent, the level of blunders found to positive experimental outcomes, and the number of mistakes found and fixed. 

Taking everything into account, this is the second for breaking down its work, summarizing the outcomes, investigating its efficiency, and the valuable chance to make ideas for working on the nature of testing.

Wrapping Up

This whole blog has shown the significance of how STLC functions for organizations. We have given an exhaustive outline of how the programming testing life cycle is not quite the same as SDLC, the distinction, and its plans. 

There are various kinds of programming testing that one can proceed with as a business, and we know which one to decide for your optimal application. 

A decent testing strategy supports business results, and hence, we profoundly encourage organizations to keep their eyes on the rock(testing). At the same time, it is confident they will come by beneficial outcomes with STLC.

Frequently Asked Questions

The 7 phases of the Software Testing Life Cycle (STLC) are:

  • Requirement Analysis: Understanding and analyzing testing requirements.
  • Test Planning: Creating a test plan outlining the testing scope, objectives, and strategy.
  • Test Design: Developing test cases, scripts, and data.
  • Test Environment Setup: Preparing the required test infrastructure and data.
  • Test Execution: Running test cases, capturing results, and reporting defects.
  • Defect Reporting: Documenting and reporting defects for resolution.
  • Test Closure: Evaluating test results, creating test summary reports, and concluding the testing phase.

Software Testing Life Cycle (STLC) is a systematic and structured approach to software testing that defines various phases and activities involved in testing a software application. It encompasses planning, designing, executing, and reporting on tests to ensure the software's quality and reliability.

The 5 stages of the Software Testing Life Cycle (STLC) are:

  • Requirement Analysis: Understanding and analyzing testing requirements based on project documentation.
  • Test Planning: Creating a comprehensive test plan that outlines testing objectives, scope, resources, and schedule.
  • Test Design: Developing detailed test cases, test scripts, and test data based on requirements.
  • Test Execution: Running the test cases, capturing results, and reporting defects.
  • Defect Reporting and Closure: Documenting and managing defects, retesting, and eventually closing them as resolved.
  • Smoke Testing: A subset of regression testing, it checks if the most critical functionalities of a software build are working correctly. It aims to determine whether the build is stable enough for further testing.
  • Sanity Testing: This narrow and focused testing effort checks specific parts of the software after code changes. It ensures that the recent changes haven't introduced critical defects.
