Software Testing Tutorial #11 - Levels in Software Testing

**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 :)

Thanks boss understood type of test levels with ease!

[@chandramartika2779]

Level of testing 1. unit testing 2. integration testing 3. system testing (system test / system integration test) 4. user acceptance testing

Super explanation sir

[@abosedeomobomi2127]

Am new to IT but you teach better than the books I bought. I just have to be your downline student.

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?
