The Software Testing Life Cycle (STLC) is a systematic and structured process that software testing teams follow to ensure the quality and reliability of a software application. STLC encompasses the various stages and activities that testers and quality assurance professionals undertake from the planning phase to the final release of the software. It is a crucial component of the software development life cycle (SDLC) and helps identify and rectify defects and issues in the software. The specific phases and activities in the STLC may vary depending on the project and organization, but a typical STLC generally includes the following stages:

1. **Requirement Analysis:** In this initial phase, testers analyze the project's requirements and specifications to understand what needs to be tested. They create test plans and strategies based on these requirements.

2. **Test Planning:** In this phase, a detailed test plan is prepared, outlining the scope of testing, objectives, deliverables, schedules, resources, and test environment requirements.

3. **Test Design:** Testers design test cases and test scenarios based on the test plan and requirements. These test cases outline the steps to be executed, the expected results, and the data to be used.

4. **Test Environment Setup:** This phase involves setting up the necessary hardware, software, and test data needed to conduct the tests effectively.

5. **Test Execution:** Testers execute the test cases in the defined environment, following the steps outlined in the test design phase. They record the actual results and compare them to the expected results.

6. **Defect Reporting:** If any discrepancies or defects are identified during the test execution phase, they are reported to the development team for resolution. A defect report typically includes a description of the defect, its severity, and steps to reproduce it.

7. **Defect Tracking:** This phase involves tracking the reported defects and monitoring their status until they are resolved. It also includes retesting the fixed defects to ensure they have been effectively addressed.

8. **Regression Testing:** After fixing defects, regression testing is performed to ensure that the changes made to the software do not introduce new issues or affect existing functionality.

9. **Test Closure:** Once testing is complete and all objectives have been met, a test summary report is generated. This report provides an overview of the testing activities, test coverage, and the quality of the software. It serves as a basis for decision-making regarding the release of the software.

10. **Test Metrics and Reporting:** Throughout the STLC, various metrics are collected to measure the effectiveness and progress of testing. Test reports are created to provide stakeholders with an overview of testing status and quality.

11. **Test Sign-Off:** At the end of the testing phase, a formal sign-off is obtained from relevant stakeholders, indicating that testing is complete, and the software is ready for release.

12. **Test Closure Activities:** This phase involves archiving test artifacts, conducting a review of the entire testing process, and identifying lessons learned for future projects.

The Software Testing Life Cycle ensures that the software product meets the specified quality standards, is reliable, and performs as expected. It is an integral part of the software development process and plays a critical role in delivering high-quality software to end-users.

Re-testing and regression testing are two different types of software testing, each serving a distinct purpose in the software development and quality assurance process. Here are the key differences between re-testing and regression testing:

**1. Purpose:**

- **Re-testing:** Re-testing focuses on testing the specific defect or issue that was found in the previous test cycle. It aims to verify whether the reported defect has been fixed correctly. The scope of re-testing is narrow and is typically limited to the test case(s) related to the identified defect.

- **Regression Testing:** Regression testing aims to ensure that new code changes or modifications to the software do not introduce new defects or negatively impact existing functionality. It verifies that the application still works correctly after new code is added, modified, or fixed. Regression testing has a broader scope and often covers a wide range of test cases.

**2. Test Cases:**

- **Re-testing:** Re-testing typically involves executing the same test case(s) that initially uncovered the defect. The test case is repeated to confirm that the defect is no longer present.

- **Regression Testing:** Regression testing involves running a suite of test cases, which includes not only the ones related to the specific defect but also other critical test cases that represent different parts of the application. The goal is to ensure that changes to the code have not adversely affected the overall system.

**3. Scope:**

- **Re-testing:** The scope of re-testing is limited to the area of the defect and the test cases directly associated with it.

- **Regression Testing:** The scope of regression testing is broader, covering a wider range of functionalities to ensure that no unintended side effects have occurred due to code changes.

**4. Timing:**

- **Re-testing:** Re-testing is typically performed after a defect has been fixed by the development team, as part of the defect verification process.

- **Regression Testing:** Regression testing is an ongoing process that is conducted whenever there are code changes or updates to the software, even if no defects were reported. It helps maintain the overall quality of the software during its development and maintenance.

In summary, re-testing is focused on confirming that a specific defect has been successfully fixed, while regression testing is aimed at ensuring that the software remains stable and functional across the board, even as new code is added or modified. Both types of testing are essential in the software testing life cycle to maintain and improve software quality.

Smoke testing and sanity testing are two types of initial testing activities performed during the software testing process, but they serve different purposes and have distinct characteristics. Here are the key differences between smoke testing and sanity testing:

**Smoke Testing:**

1. **Purpose:** Smoke testing is performed to ensure that the most critical and basic functionalities of the software application work correctly. It is designed to identify major issues that might prevent further, more detailed testing.

2. **Scope:** Smoke testing covers a broad range of features and functionalities of the software, encompassing the core aspects that are essential for the software to perform its primary functions.

3. **Timing:** Smoke testing is typically performed early in the testing process, often after a build is received from the development team. It ensures that the build is stable and fit for further, more comprehensive testing.

4. **Depth:** Smoke tests are generally not detailed or comprehensive. Test cases for smoke testing are typically limited in number and focus on basic, high-level functionality.

5. **Pass/Fail Criteria:** Smoke tests have a binary pass/fail outcome. If the software passes the smoke test, it is considered stable and ready for further testing. If it fails, the build is rejected and sent back to the development team for corrections.

6. **Regression:** Smoke tests are considered a form of regression testing but are more lightweight and focused on the most critical functions.

**Sanity Testing:**

1. **Purpose:** Sanity testing is performed to verify specific, newly added or modified functionalities or features. It ensures that these specific changes have not introduced major defects and that the software remains generally stable.

2. **Scope:** Sanity testing focuses on a narrow, specific set of functionalities, often those related to the recent changes or additions in the code. It is not concerned with the overall coverage of the application.

3. **Timing:** Sanity testing is typically carried out after a specific code change, bug fix, or minor feature addition, rather than at the beginning of the testing process. It helps confirm that the immediate changes have not adversely affected the application.

4. **Depth:** Sanity tests can be more detailed and specific than smoke tests, as they are geared towards the specific areas of code that have been modified.

5. **Pass/Fail Criteria:** Similar to smoke tests, sanity tests also have a binary pass/fail outcome. If the sanity tests pass, it indicates that the recent changes or additions have not broken critical functionality. If they fail, it suggests issues related to the recent code changes.

6. **Regression:** While sanity testing can be seen as a form of regression testing, it is more focused on the specific, recent modifications, and it is performed to ensure that these changes have not negatively impacted the application.

In summary, smoke testing evaluates the overall stability of the software by focusing on critical functionalities, while sanity testing checks specific changes or newly added features to ensure that they haven't introduced major issues. Both types of testing are essential in the software testing process, with smoke testing serving as an initial gatekeeper, and sanity testing providing targeted verification for recent code changes.

Functional testing and non-functional testing are two fundamental types of software testing, each with its own focus and objectives. Here are the key differences between them:

**Functional Testing:**

1. **Purpose:** Functional testing evaluates whether a software application or system functions as expected by testing its features, functionality, and behavior according to the specified requirements.

2. **Focus:** It primarily focuses on what the software is supposed to do. Functional tests verify if the application performs its intended functions correctly, including user interactions, data processing, and system responses.

3. **Testing Criteria:** Functional testing is based on the documented requirements and specifications of the software. Test cases are designed to verify whether the application meets these requirements.

4. **Examples:** Unit testing, integration testing, system testing, and acceptance testing are common types of functional testing. These tests address various levels of the software and ensure it meets functional specifications.

5. **Verdict:** Functional testing results in either a pass (if the software behaves as expected) or a fail (if it doesn't).

**Non-Functional Testing:**

1. **Purpose:** Non-functional testing, also known as quality attributes or performance testing, assesses the software's non-functional characteristics, such as performance, reliability, security, usability, and scalability.

2. **Focus:** It focuses on how the software operates rather than what it does. Non-functional tests evaluate attributes like speed, security, user experience, and robustness.

3. **Testing Criteria:** Non-functional testing is often based on quality attributes and user expectations, not just explicit requirements. These attributes are often harder to quantify and may vary depending on user needs.

4. **Examples:** Non-functional testing includes various types, such as performance testing (e.g., load testing, stress testing), security testing, usability testing, reliability testing, and compatibility testing. These tests assess different aspects of software quality.

5. **Verdict:** Non-functional testing typically provides a range of results or performance metrics rather than a binary pass/fail outcome. For example, a performance test might provide response times, throughput, and error rates, allowing stakeholders to determine if the application meets performance criteria.

In summary, functional testing ensures that the software's features and functions meet the specified requirements, while non-functional testing focuses on the quality attributes that determine how well the software operates. Both types of testing are essential for comprehensive software testing to ensure that the software not only works correctly but also meets the non-functional criteria for performance, security, usability, and other important aspects of software quality.
