## Negative results
- **Error**: Mistake made by a human
- **Fault**: A manifestation of an error in software
- **Bug and Defect** are basically the same as Fault
- **Failure**: Inability of a system or component to perform its required function


## Types of tests

### Functional testing

| Fancy Words         | Simpler Explanation                                                                                                  | Stupid Dumb Word       |
| ------------------- | -------------------------------------------------------------------------------------------------------------------- | ---------------------- |
| Unit Testing        | Testing individual components or pieces of code in isolation.                                                        | Piece by piece testing |
| Integration Testing | Testing the interaction between integrated modules or components to ensure they work together as expected.           | Mix and match testing  |
| System Testing      | Testing the entire system as a whole to verify it meets specified requirements.                                      | Whole thing testing    |
| Acceptance Testing  | Testing to determine whether the system meets the business needs and requirements, often performed by the end-users. | Ready or not           |
| Regression Testing  | Re-running tests to ensure that new code changes haven’t broken existing functionality.                              | Did we break it again? |
| Sanity Testing      | A quick round of testing to check if a specific function or bug fix works as intended.                               | Quick check testing    |
| Smoke Testing       | A basic check to ensure the software’s core functionality works and it's stable enough for more in-depth testing.    | Is it on fire?         |
| Usability Testing   | Testing how user-friendly and intuitive the software is for the end-user.                                            | Easy of use testing    |

### Non-functional testing

| Fancy Words           | Simpler Explanation                                                                       | Stupid Dumb Word           |
| --------------------- | ----------------------------------------------------------------------------------------- | -------------------------- |
| Performance Testing   | Testing how well the software performs under different conditions.                        | How fast does it run?      |
| Load Testing          | Testing how the software behaves under expected user load.                                | How much can it carry?     |
| Stress Testing        | Testing the limits of the software by pushing it beyond normal operational capacity.      | When will it break?        |
| Volume Testing        | Testing the software with a large amount of data to see if it handles it well.            | How much data can it take? |
| Scalability Testing   | Testing how well the software scales when the user load or data volume increases.         | Can it grow?               |
| Recovery Testing      | Testing the software's ability to recover after a failure or crash.                       | Can it unfuck itself?      |
| Compatibility Testing | Testing how well the software works across different environments, platforms, or devices. | Does it work with others?  |
| Security Testing      | Testing how well the software protects against unauthorized access and vulnerabilities.   | Can it be broken into?     |

## Black box vs White box


| Black box                         | White box              |
| --------------------------------- | ---------------------- |
| Done by tester                    | Done by devs           |
| Internal code unknown             | Knowledge is required  |
| Functional testing                | Structure testing      |
| No programming skills necessary   | bruh                   |
| Do it break, do it work, is nice? | Do it cover all cases? |
