Method Detail

isEqualTo

public ByteAssert isEqualTo(byte 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 ByteAssert isNotEqualTo(byte 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.

isZero

public ByteAssert isZero()
Verifies that the actual value is equal to zero.

Specified by:
isZero in interface NumberAssert<Byte>
Returns:
this assertion object.

isNotZero

public ByteAssert isNotZero()
Verifies that the actual value is not equal to zero.

Specified by:
isNotZero in interface NumberAssert<Byte>
Returns:
this assertion object.

isPositive

public ByteAssert isPositive()
Verifies that the actual value is positive.

Specified by:
isPositive in interface NumberAssert<Byte>
Returns:
this assertion object.

isNegative

public ByteAssert isNegative()
Verifies that the actual value is negative.

Specified by:
isNegative in interface NumberAssert<Byte>
Returns:
this assertion object.

isLessThan

public ByteAssert isLessThan(byte other)
Verifies that the actual value is less than 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 or greater than the given one.

isLessThanOrEqualTo

public ByteAssert isLessThanOrEqualTo(byte other)
Verifies that the actual value is less than or 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 greater than the given one.

isGreaterThan

public ByteAssert isGreaterThan(byte other)
Verifies that the actual value is greater than 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 or less than the given one.

isGreaterThanOrEqualTo

public ByteAssert isGreaterThanOrEqualTo(byte other)
Verifies that the actual value is greater than or 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 less than the given one.

usingComparator

public ByteAssert usingComparator(Comparator<?> 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.

Example :
 // compares invoices by payee 
 assertThat(invoiceList).usingComparator(invoicePayeeComparator).isEqualTo(expectedInvoiceList).
 
 // compares invoices by date, doesNotHaveDuplicates and contains both use the given invoice date comparator
 assertThat(invoiceList).usingComparator(invoiceDateComparator).doesNotHaveDuplicates().contains(may2010Invoice)
 
 // as assertThat(invoiceList) creates a new assertion, it uses standard comparison strategy (Invoice's equal method) to compare invoiceList elements to lowestInvoice.                                                      
 assertThat(invoiceList).contains(lowestInvoice).
 
Custom comparator is not parameterized with actual type A (ie. Comparator<A>) because if it was, we could not write the following code :
 // frodo and sam are instances of Character (a Character having a Race)
 // raceComparator implements Comparator<Character> 
 // assertThat(frodo) returns an ObjectAssert and not a custom CharacterAssert implementing Assert<CharacterAssert, Character>  
 assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam); // won't compile !
 
 The code does not compile because assertThat(frodo) returns an ObjectAssert, thus usingComparator expects a Comparator<Object> 
 and Comparator<Character> is not a Comparator<Object> as generics are not reified.
 
 Note that, it would have worked if assertThat(frodo) returned a CharacterAssert implementing Assert<CharacterAssert, Character>. 
 

Specified by:
usingComparator in interface Assert<ByteAssert,Byte>
Overrides:
usingComparator in class AbstractComparableAssert<ByteAssert,Byte>
Parameters:
customComparator - the comparator to use for incoming assertion checks.
Returns:
this assertion object.

usingDefaultComparator

public ByteAssert 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<ByteAssert,Byte>
Overrides:
usingDefaultComparator in class AbstractComparableAssert<ByteAssert,Byte>
Returns:
this assertion object.
