Method Detail

absDiffback to summary
protected abstract NUMBER absDiff(final NUMBER actual, final NUMBER other)
areEqualback to summary
protected boolean areEqual(final NUMBER value, final NUMBER other)

Overrides org.assertj.core.internal.Comparables.areEqual.

assertIsBetweenback to summary
public void assertIsBetween(AssertionInfo info, NUMBER actual, NUMBER start, NUMBER end)

Asserts that the actual value is in [start, end] range (start included, end included).

Parameters
info:AssertionInfo

contains information about the assertion.

actual:NUMBER

the actual value.

start:NUMBER

range start value

end:NUMBER

range end value

Exceptions
AssertionError:
  • if the actual value is null.
  • if the actual value is positive.
  • if the actual value is not in [start, end] range.
NullPointerException:
  • if start value is null.
  • if end value is null.
assertIsCloseToback to summary
public void assertIsCloseTo(final AssertionInfo info, final NUMBER actual, final NUMBER expected, final Offset<NUMBER> offset)

Asserts that the actual value is close to the expected one by less than the given offset.

It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.

Parameters
info:AssertionInfo

contains information about the assertion.

actual:NUMBER

the actual value.

expected:NUMBER

the value to compare actual too.

offset:Offset<NUMBER>

the given positive offset.

public void assertIsCloseToPercentage(final AssertionInfo info, final NUMBER actual, final NUMBER other, final Percentage percentage)

Asserts that the actual value is close to the an offset expressed as an percentage value.

Parameters
info:AssertionInfo

contains information about the assertion.

actual:NUMBER

the actual value.

other:NUMBER

Asserts that the actual value is negative.

Parameters
info:AssertionInfo

the actual value.

Exceptions
AssertionError:
  • if the actual value is null.
  • if the actual value is not negative: it is either equal to or greater than zero.
