Method Detail

hasSameSizeAs

public S hasSameSizeAs(Object other)

Verifies that the actual group has the same size as given array.

Parameter is declared as Object to accept both Object[] and primitive arrays (e.g. int[]).

Example:

 int[] oneTwoThree = {1, 2, 3};
 Iterable<Ring> elvesRings = newArrayList(vilya, nenya, narya); 
 
 // assertions will pass
 assertThat(elvesRings).hasSameSizeAs(oneTwoThree);

Example with byte array:

 // assertions will pass
 assertThat(new byte[]{1, 2}).hasSameSizeAs(new byte[]{2, 3});
 assertThat(new byte[]{1, 2}).hasSameSizeAs(new Byte[]{2, 3});
 assertThat(new byte[]{1, 2}).hasSameSizeAs(new int[]{2, 3});
 assertThat(new byte[]{1, 2}).hasSameSizeAs(new String[]{"1", "2"});

 // assertion will fail
 assertThat(new byte[]{ 1, 2 }).hasSameSizeAs(new byte[]{ 1, 2, 3 });

Specified by:

hasSameSizeAs in interface EnumerableAssert<AbstractEnumerableAssert<S extends AbstractEnumerableAssert<S,A,E>,A,E>,E>

Parameters:

other - the array to compare size with actual group.

Returns:

this assertion object.

inHexadecimal

public S inHexadecimal()

Enable hexadecimal object representation of Iterable elements instead of standard java representation in error messages.

It can be useful to better understand what the error was with a more meaningful error message.

Example

 assertThat(new byte[]{0x10,0x20}).inHexadecimal().contains(new byte[]{0x30});

With standard error message:

 Expecting:
  <[16, 32]>
 to contain:
  <[48]>
 but could not find:
  <[48]>

With Hexadecimal error message:

 Expecting:
  <[0x10, 0x20]>
 to contain:
  <[0x30]>
 but could not find:
  <[0x30]>

Overrides:

inHexadecimal in class AbstractAssert<S extends AbstractEnumerableAssert<S,A,E>,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 AbstractEnumerableAssert<S,A,E>,A>

Returns:

this assertion object.
