Assertions are the core implementation of writing test cases, that is, what the expected value is, and how much is the result of the test to determine whether the test passed.

Assertion Core Method

See if two arrays are equal.

assertarrayequals (expecteds, actuals)
assertequals (expected, actual)	to see if two objects are equal. The Equals () method, similar to string comparisons,
assertnotequals (first, second)	to see whether two objects are not equal.
assertnull (object)	to see if the object is empty.
assertnotnull (object)	to see if the object is not empty.
assertsame (expected, actual)	to see whether references to two objects are equal. Similar to using "= =" to compare two objects
assertnotsame (Unexpected, actual)	to see whether references to two objects are not equal. Similar to using "! =" to compare two objects
asserttrue (condition)	to see if the run result is true.
assertfalse (condition)	to see if the run result is false.
assertthat (Actual, matcher)	See if the actual value meets the specified condition
fail ()	let test fail

Annotations

@Before	Initialize method
@After	Freeing resources
@Test	Test method, where you can test for expected exceptions and time-outs
@Ignore	Ignored test methods
@BeforeClass	For all tests, execute only once and must be static void
@AfterClass	For all tests, execute only once and must be static void
@RunWith	Specifies that a test class uses a runner
@Parameters	To specify a test data collection for a test class
@Rule	Allows flexibility to add or redefine the behavior of each test method in a test class
@FixMethodOrder	Specify the order in which test methods are executed

A Test class unit test is executed in the following order:

@BeforeClass –> @Before –> @Test –> @After –> @AfterClass

The order in which each test method is called is:

@Before –> @Test –> @After
