JUnit 4 New assertion: A common approach to hamcrest

One, character-related matching characters

1, Equalto:

Assertthat (Testedvalue, Equalto (Expectedvalue));

Asserts that the measured testedvalue equals Expectedvalue,equalto can assert the equality between the values, between strings and objects, equivalent to the Equals method of object

2, Equaltoignoringcase:

Assertthat (testedstring, Equaltoignoringcase (expectedstring));

asserts that the string testedstring is measured is equal to expectedstring if the case is ignored

3, Equaltoignoringwhitespace:

Assertthat (testedstring, Equaltoignoringwhitespace (expectedstring);

asserts that the string testedstring is measured is equal to expectedstring if any of the trailing spaces are ignored

(Note: Spaces in a string cannot be ignored)

4, Containsstring:

Assertthat (testedstring, containsstring (subString));

Asserts that the measured string testedstring contains substrings substring

5, EndsWith:

Assertthat (testedstring, endsWith (suffix));

Assertion that the measured string testedstring ends with a substring suffix

6, StartsWith:

Assertthat (testedstring, startswith (prefix));

asserts that the string testedstring being measured starts with a substring prefix

Two, the general match character

1, Nullvalue ():

Assertthat (Object,nullvalue ());

Asserts that the value of the object being measured is null*/

2, Notnullvalue ():

Assertthat (Object,notnullvalue ());

Asserts that the value of the object being measured is not null*/

3, is:

Assertthat (Testedstring, is (Equalto (expectedvalue));

Asserts that the object being measured is equal to the following given matching expression

1 is a matching character shorthand application one:

Assertthat (Testedvalue, is (Expectedvalue));

The shorthand for IS (Equalto (x)), the assertion testedvalue equals Expectedvalue

2 is a matching character shorthand application of the second:

Assertthat (Testedobject, is (Cheddar.class));

Is (instanceof (someclass.class)) shorthand, assertion Testedobject as an instance of Cheddar

4, not:

Assertthat (testedstring, not (expectedstring));

Contrary to an is match, the assertion that the object being measured is not equal to the object given later
