Hamcrest Quick Start: Enhanced JUnit syntax and capabilities

Explore hamcrest's array methods in JUnit tests by using empty array, has size, and contains variants, including order-sensitive and order-insensitive assertions, with string, integer, and custom object arrays.

Learn Hamcrest collection methods for lists, sets, and maps to assert emptiness, size, containment, order, and exact key-value entries.

Explore Hamcrest object and null value matchers, including instance of and anything, with strings, lists, maps, and class hierarchies, and learn to assert null, not null, and class membership.

Learn to build a parameterized Hamcrest custom matcher by extending TypeSafeMatcher, implementing matchesSafely and describedTo, to verify the left value equals the sum of three constructor inputs.

Learn to implement a custom Hamcrest starts with matcher for strings, using a type safe matcher, and validate case sensitivity with practical tests like Apple and banana.

Write and test a custom Hamcrest matcher named alphanumeric to recognize non-empty strings that contain only digits or English letters, using a type safe matcher and a JUnit test runner.

Explore Hamcrest methods for Java beans, using hasProperty, equalTo, samePropertyValuesAs, and not to verify bean fields such as name and number in a football player example.

Conclude your Hamcrest quick start by understanding how Hamcrest works, using its methods, and writing custom matches, then apply these skills to your own projects.
