In addition to major testing types, this section briefly describes other important testing methodologies such as system testing, regression testing, performance testing, and smoke testing, highlighting their purpose and significance in the software development lifecycle.

Other Testing Types (Brief Overview)
Introduction
This section expands the understanding of software testing by introducing additional methodologies outside the foundational types highlighted previously.
Types of Testing
- System Testing: This involves end-to-end testing of the entire application to ensure that all components work together as expected.
- Regression Testing: This type verifies that recent code changes havenβt adversely affected existing features of the software; it helps maintain software integrity after updates.
- Performance Testing: This evaluates the application's behavior under load, assessing aspects such as speed and stability.
- Smoke Testing: Often referred to as

End-to-end testing of the entire application.
Detailed Explanation
System Testing involves checking the entire application to ensure that all components work together as expected. This type of testing validates the complete and integrated software product against its specifications.
Examples & Analogies
Imagine a car manufacturer conducting a test drive of a complete car instead of just testing individual parts like the engine or brakes. They would check if the car starts, runs smoothly, and all systems work together (like the lights, wipers, and heating) before it is sold to customers.
Regression Testing

Testing after code changes to ensure old features still work.
Detailed Explanation
Regression Testing is performed after updates or changes in the codebase to verify that existing functionalities are unaffected. This helps ensure that new code changes don't introduce any new bugs or disrupt previously working features.
Examples & Analogies
Think of regression testing like a home renovation. When you change the kitchen layout, you want to ensure that the plumbing and electrical systems still function properly after the work is done. You wouldnβt want to turn on the lights and find they no longer work because of the renovations.

Test app behavior under load (speed, stability).
Detailed Explanation
Performance Testing is conducted to assess how well the application performs under various conditions, such as high traffic or heavy data loads. This type of testing helps identify areas where the application may slow down or fail under stress.
Examples & Analogies
Consider a restaurant during a dinner rush. They need to ensure that the kitchen can handle multiple orders at once without becoming overwhelmed and serving food too slowly. Performance testing checks if the software can sustain its operation under heavy use, much like ensuring the kitchen runs efficiently when busy.

Initial testing to check if the build is testable.
Detailed Explanation
Smoke Testing is a preliminary test to check the basic functionality of an application. It verifies that the most critical parts of the application are working and that it can proceed to more rigorous testing phases. If smoke tests fail, the build is not considered stable enough for further testing.
Examples & Analogies
Itβs similar to a pilot checking the basic controls and indicators in an airplane before taking off. If major issues are detected during this basic check, the flight would be canceled until those issues are resolved, ensuring safety before heading into a more complex journey.
