Method Detail

isLessThan

public S isLessThan(A other)

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

Specified by:

isLessThan in interface ComparableAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Parameters:

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

Returns:

this assertion object.

isLessThanOrEqualTo

public S isLessThanOrEqualTo(A other)

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

Specified by:

isLessThanOrEqualTo in interface ComparableAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Parameters:

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

Returns:

this assertion object.

isGreaterThan

public S isGreaterThan(A other)

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

Specified by:

isGreaterThan in interface ComparableAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Parameters:

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

Returns:

this assertion object.

isGreaterThanOrEqualTo

public S isGreaterThanOrEqualTo(A other)

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

Specified by:

isGreaterThanOrEqualTo in interface ComparableAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Parameters:

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

Returns:

this assertion object.

usingComparator

public S usingComparator(Comparator<? super A> 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 AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Overrides:

usingComparator in class AbstractAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

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 AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Overrides:

usingDefaultComparator in class AbstractAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Returns:

this assertion object.

inHexadecimal

public S inHexadecimal()

Description copied from class: AbstractAssert

Use hexadecimal object 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 message:

 assertThat("µµµ").contains("μμμ");

 java.lang.AssertionError:
 Expecting:
   <"µµµ">
 to contain:
   <"μμμ">
 

With Hexadecimal message:

 assertThat("µµµ").inHexadecimal().contains("μμμ");

 java.lang.AssertionError:
 Expecting:
   <"['00B5', '00B5', '00B5']">
 to contain:
   <"['03BC', '03BC', '03BC']">
 

Overrides:

inHexadecimal in class AbstractAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>

Returns:

this assertion object.

inBinary

public S inBinary()

Description copied from class: AbstractAssert

Use binary object representation instead of standard representation in error messages.

Example:

 assertThat(1).inBinary().isEqualTo(2);

 org.junit.ComparisonFailure:
 Expected :0b00000000_00000000_00000000_00000010
 Actual   :0b00000000_00000000_00000000_00000001


Overrides:
inBinary in class AbstractAssert<S extends AbstractComparableAssert<S,A>,A extends Comparable<? super A>>



Returns:
this assertion object.
