How do you properly test a code?

Here we go.

1. Test One Thing at a Time in Isolation.
2. Follow the AAA Rule: Arrange, Act, Assert.
3. Write Simple “Fastball-Down-the-Middle” Tests First.
4. Test Across Boundaries.
5. If You Can, Test the Entire Spectrum.
6. If Possible, Cover Every Code Path.
7. Write Tests That Reveal a Bug, Then Fix It.
8. Make Each Test Independent.

Why do we test our code?

Developers write unit tests for their code to make sure that the code works correctly. This helps to detect and protect against bugs in the future. Sometimes developers write unit tests first, then write the code. This approach is also known as test-driven development (TDD).

What is code level testing?

It examines means of making code test itself, ways to direct testing for maximum effect, and describes some of the issues associated with managing and reproducing test procedures.

When to use testing instead of running code?

When something goes wrong or has to be changed, and if your code has a good set of tests, you or other maintainers will rely largely on the testing suite to fix the problem or modify a given behavior. Therefore the testing code will be read as much as or even more than the running code.

Which is the first step in debugging your code?

The first step when you are debugging your code is to write a new test pinpointing the bug. While it is not always possible to do, those bug catching tests are among the most valuable pieces of code in your project. Use long and descriptive names for testing functions.

Which is AWS glue version do I Need?

Is the glue Scala library available on AWS?
