What types of testing are usually used when testing software?

When testing software, several types of testing are usually used:

• Unit Testing — testing individual functions or methods.
• Integration Testing — testing the interaction between modules.
• Functional Testing — verifying that the functionality meets the requirements.
• System Testing — testing the entire system as a whole.
• Acceptance Testing — verifying the product's readiness for use by the customer.
• Regression Testing — ensuring that changes haven't broken existing functionality.
• Load Testing — testing behavior under high load.

In Go, unit tests are often written using the testing package.
