**Software Testing Tutorial #11 - Levels in Software Testing - Notes**
**Understanding Testing Levels:**
- Testing levels refer to distinct stages where software is tested for reliability, functionality, and quality.
- These levels are separate from testing types, which represent specific testing methodologies.
**Four Core Testing Levels:**
- Software testing encompasses four fundamental testing levels, ensuring comprehensive scrutiny before software reaches end-users.
**1. Unit Testing:**
- Unit testing starts the journey by testing the smallest components of an application.
- For example, in a login page, elements like username field, password field, and login button are tested individually.
- Developers often handle unit testing, verifying component quality and functionality.
**2. Integration Testing:**
- Integration testing follows unit testing, focusing on integrating tested components.
- In the login page example, integrated testing involves ensuring username field, password field, and login button interact harmoniously.
- Testers typically manage integration testing, examining component interactions and compatibility.
**3. System Testing:**
- System testing evaluates the entire software system as a cohesive unit.
- It ensures the software functions as intended.
- In standalone software, it's System Testing (ST); in software interacting with external systems, it's System Integration Testing (SIT).
**4. User Acceptance Testing (UAT):**
- UAT is the culmination of testing, involving real users representing customers or stakeholders.
- Users evaluate software's readiness, alignment with needs, and value addition.
- UAT feedback guides final adjustments before official software launch.
**Importance of Understanding Testing Levels:**
- Understanding testing levels is foundational in software testing.
- These levels serve as a roadmap, ensuring software quality, functionality, and user satisfaction.
- Effective collaboration between developers, testers, and users is facilitated by these levels.
**Interaction with Testing Types:**
- As expertise deepens, understanding testing types enhances testing strategies.
- Testing levels and types complement each other for comprehensive testing methodologies.
**Conclusion:**
- Testing levels form universal pillars in software testing.
- They provide structure, guiding software testing processes effectively.
- Collaboration between developers, testers, and users is streamlined.
- As you progress, mastery of testing levels and types aids in crafting tailored testing strategies.

I am a little bit confused as you say that testers are responsible for Integration testing but many other courses/sites/whatnot I've looked at claim that it is developer's responsibility. Could you please try to clarify how a tester, with no coding experience, would participate in Integration testing? On the side note, Good job, I really enjoy your videos, you know your craft and you know how to explain it. Thank you :)

Hello Sir, Is testing team responsible for System and user Acceptance Testing or developers and end users have any role on this?

Aren`t a Unit and Component different types?
