Software Testing Life Cycle (STLC)

The Software Testing Life Cycle (STLC) is a structured process that outlines specific phases followed by QA teams to ensure software testing is conducted systematically. While the Software Development Life Cycle (SDLC) emphasizes software development, STLC focuses on the various steps critical to testing, including requirement analysis, test planning, test case development, and execution. Each phase has defined entry and exit criteria to maintain quality and accountability throughout the testing process.

Software Testing Life Cycle (STLC)

The Software Testing Life Cycle (STLC) outlines the process and phases followed by QA teams to conduct systematic and effective software testing.

3 Section Overview

Start current section content and materials

3.1 Phases of STLC

The Phases of the Software Testing Life Cycle (STLC) outline a structured process followed by QA teams to ensure efficient and effective testing.

3.1.1 Requirement Analysis

Requirement Analysis is the first phase of the Software Testing Life Cycle (STLC) that focuses on understanding and identifying testable requirements.

3.1.2 Test Planning

Test Planning defines the strategies, scope, objectives, and logistics of the testing process, crucial for effective software quality assurance.

3.1.3 Test Case Development

This section emphasizes the importance of designing detailed test cases and preparing test data as part of the Testing Phase in the Software Testing Life Cycle (STLC).

3.1.4 Test Environment Setup (Parallel Phase)

This section discusses the crucial phase of test environment setup in the Software Testing Life Cycle (STLC), emphasizing the preparation of hardware and software necessary for testing activities.

3.1.5 Test Execution

Test Execution is a critical phase in the Software Testing Life Cycle, focused on executing test cases and reporting any defects found.

3.1.6 Test Cycle Closure

The Test Cycle Closure phase formally concludes the testing activities by assessing metrics and documenting learnings.

Learning Objectives

  • STLC emphasizes the importance of a structured approach to software testing.

  • Each phase within STLC has specific deliverables, ensuring thorough documentation and accountability.

  • The importance of entry and exit criteria in maintaining quality control and managing testing progression.

Key Concepts

Requirement Analysis

A phase in STLC focused on understanding what needs to be tested by reviewing various requirement documents and identifying testable requirements.

Test Execution

The phase in the STLC where test cases are executed, defects are logged, and the actual outcomes are compared with expected results.

Entry and Exit Criteria

Conditions that must be satisfied before a phase begins (entry criteria) and must be fulfilled before moving on to the next phase (exit criteria) within STLC.

Test Plan Document

A deliverable produced during the Test Planning phase that outlines the strategy, scope, and logistics for the testing process.

Test Summary Report

A document produced during the Test Cycle Closure phase that summarizes the outcomes of testing activities and may include lessons learned.
