Method Summary

void	assertIsBetween(AssertionInfo info, NUMBER actual, NUMBER start, NUMBER end) Asserts that the actual value is in [start, end] range (start included, end included).
void	assertIsNegative(AssertionInfo info, NUMBER actual) Asserts that the actual value is negative.
void	assertIsNotNegative(AssertionInfo info, NUMBER actual) Asserts that the actual value is not negative.
void	assertIsNotPositive(AssertionInfo info, NUMBER actual) Asserts that the actual value is not positive.
void	assertIsNotZero(AssertionInfo info, NUMBER actual) Asserts that the actual value is not equal to zero. It does not rely on the custom comparisonStrategy (if one is set).
void	assertIsPositive(AssertionInfo info, NUMBER actual) Asserts that the actual value is positive.
void	assertIsStrictlyBetween(AssertionInfo info, NUMBER actual, NUMBER start, NUMBER end) Asserts that the actual value is in ]start, end[ range (start excluded, end excluded).
void	assertIsZero(AssertionInfo info, NUMBER actual) Asserts that the actual value is equal to zero. It does not rely on the custom comparisonStrategy (if one is set).

protected abstract NUMBER zero()

assertIsZero

public void assertIsZero(AssertionInfo info,
                         NUMBER actual)

Asserts that the actual value is equal to zero.
It does not rely on the custom comparisonStrategy (if one is set).

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is not equal to zero.

assertIsNotZero

public void assertIsNotZero(AssertionInfo info,
                            NUMBER actual)

Asserts that the actual value is not equal to zero.
It does not rely on the custom comparisonStrategy (if one is set).

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is equal to zero.

assertIsNegative

public void assertIsNegative(AssertionInfo info,
                             NUMBER actual)

Asserts that the actual value is negative.

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is null.

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

assertIsPositive

public void assertIsPositive(AssertionInfo info,
                             NUMBER actual)

Asserts that the actual value is positive.

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is not positive: it is either equal to or less than zero.

assertIsNotNegative

public void assertIsNotNegative(AssertionInfo info,
                                NUMBER actual)

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is negative.

assertIsNotPositive

public void assertIsNotPositive(AssertionInfo info,
                                NUMBER actual)

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is null.

AssertionError - if the actual value is positive.

assertIsBetween

public void assertIsBetween(AssertionInfo info,
                            NUMBER actual,

assertIsStrictlyBetween

public void assertIsStrictlyBetween(AssertionInfo info,
                                    NUMBER actual,
                                    NUMBER start,
                                    NUMBER end)

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

Parameters:
