Method Detail

isEqualTo

public S isEqualTo(char expected)

Verifies that the actual value is equal to the given one.

Parameters:

expected - the given value to compare the actual value to.

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is not equal to the given one.

isNotEqualTo

public S isNotEqualTo(char other)

Verifies that the actual value is not equal to the given one.

Parameters:

other - the given value to compare the actual value to.

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is equal to the given one.

isLessThan

public S isLessThan(char other)

Verifies that the actual value is less than the given one.

Example:

 // assertion will pass
 assertThat('A').isLessThan('a');
 assertThat('a').isLessThan('b');

 // assertion will fail
 assertThat('a').isLessThan('A');
 assertThat('b').isLessThan('a');
 

Parameters:

other - the given value to compare the actual value to.

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is equal to or greater than the given one.

isLessThanOrEqualTo

public S isLessThanOrEqualTo(char other)

Verifies that the actual value is less than or equal to the given one.

Example:

 // assertion will pass
 assertThat('A').isLessThanOrEqualTo('a');
 assertThat('A').isLessThanOrEqualTo('A');

 // assertion will fail
 assertThat('b').isLessThanOrEqualTo('a');
 

Parameters:

other - the given value to compare the actual value to.

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is greater than the given one.

isGreaterThan

public S isGreaterThan(char other)

Verifies that the actual value is greater than the given one.

Example:

 // assertion will pass
 assertThat('a').isGreaterThan('A');
 assertThat('b').isGreaterThan('a');

 // assertion will fail
 assertThat('A').isGreaterThan('a');
 assertThat('a').isGreaterThan('b');
 

Parameters:

other - the given value to compare the actual value to.

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is equal to or less than the given one.

inUnicode

public S inUnicode()

Use unicode character representation instead of standard representation in error messages.

It can be useful when comparing UNICODE characters - many unicode chars have duplicate characters assigned, it is thus impossible to find differences from the standard error message:

With standard error message:

 assertThat('µ').isEqualTo('μ');

 org.junit.ComparisonFailure:
 Expected :'μ'
 Actual   :'µ'
 

With unicode based error message:

 assertThat('µ').inUnicode().isEqualTo('μ');

 org.junit.ComparisonFailure:
 Expected :μ
 Actual   :µ
 

Returns:

this assertion object.

isGreaterThanOrEqualTo

public S isGreaterThanOrEqualTo(char other)

Verifies that the actual value is greater than or equal to the given one.

Example:

 // assertion will pass
 assertThat('A').isGreaterThanOrEqualTo('A');
 assertThat('b').isGreaterThanOrEqualTo('a');
 
 // assertion will fail
 assertThat('a').isGreaterThanOrEqualTo('b');
 

Parameters:

other - the given value to compare the actual value to.

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is less than the given one.

isLowerCase

public S isLowerCase()

Verifies that the actual value is a lowercase character.

Example:

 // assertion will pass
 assertThat('a').isLowerCase();

 // assertion will fail
 assertThat('A').isLowerCase();
 

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is not a lowercase character.

isUpperCase

public S isUpperCase()

Verifies that the actual value is a uppercase character.

Example:

 // assertion will pass
 assertThat('A').isLowerCase();
 
 // assertion will fail
 assertThat('a').isLowerCase();
 

Returns:

this assertion object.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is not a uppercase character.

usingComparator

public S usingComparator(Comparator<? super Character> customComparator)

Description copied from class: AbstractAssert

Use given custom comparator instead of relying on actual type A equals method for incoming assertion checks.

Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.

Examples :

 // frodo and sam are instances of Character with Hobbit race (obviously :).
 // raceComparator implements Comparator<Character> 
 assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam); 
 

Specified by:

usingComparator in interface Assert<S extends AbstractCharacterAssert<S>,Character>

Overrides:

usingComparator in class AbstractComparableAssert<S extends AbstractCharacterAssert<S>,Character>

Parameters:

customComparator - the comparator to use for incoming assertion checks.

Returns:

this assertion object.

usingDefaultComparator

public S usingDefaultComparator()

Description copied from class: AbstractAssert

Revert to standard comparison for incoming assertion checks.

This method should be used to disable a custom comparison strategy set by calling Assert.usingComparator(Comparator).

Specified by:

usingDefaultComparator in interface Assert<S extends AbstractCharacterAssert<S>,Character>

Overrides:

usingDefaultComparator in class AbstractComparableAssert<S extends AbstractCharacterAssert<S>,Character>

Returns:

this assertion object.
