Both Jetty and Netty execute the same code--generate 8k of random bits and compute a sha1, returning it over the wire.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.
_____________________________________

## General rules
1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

# Creates an alias called "git hist" that outputs a nicely formatted git log.
# Usage is just like "git log"
# Examples:
#   git hist
#   git hist -5
#   git hist <branch_name>
#   git hist <tag_name> -10
##
git config --global alias.hist "log --pretty=format:'%C(yellow)[%ad]%C(reset) %C(green)[%h]%C(reset) | %C(red)%s %C(bold red){{%an}}%C(reset) %C(blue)%d%C(reset)' --graph --date=short"

By default surefire configuration includes tests matching "/Test*.java", "/_Test.java" or "/_TestCase.java" pattern.
By default failsafe configuration includes tests matching "/IT*.java", "/_IT.java" or "/_ITCase.java" pattern.

Usage:
mvn install -DskipUTs : Skips Unit tests
mvn install -DskipITs : Skips Integration tests
mvn install -DskipTests : Skips both Unit and Integration Tests

There is no doubt about the need for automated tests.
They

assure refactoring steps
help to detect weaknesses in the implementation
document the implemented logic
enable the implementation of modules, even if some basic modules are still missing (mocking)
Basically tests consist of 3 steps: Arrange, Act and Assert. That means establishing the test environment (Arrange), executing the logic (Act) and verifying the expectation (Assert).
Consider a bank account with the possibility to deposit money as a simple example. The implementation in advance:
