Method Detail

expectDouble

public static ExpectDouble expectDouble(Double actual)

Check for non-null Double and provided further checks on the actual double in a fluent API.

Parameters:

actual - The double to check.

Returns:

A ExpectDouble to express further expectations on the actual double.

isCloseTo

public ExpectDouble isCloseTo(Double expected,
                              Double eps)

Checks, if actual is close to expected regarding eps.

Mathematically |actual - expected| < eps

Parameters:

expected - The expected double near of actual.

eps - Epsilon value.

isNotCloseTo

public ExpectDouble isNotCloseTo(Double expected,
                                 Double eps)

Checks, if actual is not close to expected regarding eps.

Mathematically |actual - expected| >= eps

Parameters:

expected - The expected double near of actual.

eps - Epsilon value.

isNaN

public ExpectDouble isNaN()

Checks, if actual is not a number (NaN).

isNotNaN

public ExpectDouble isNotNaN()

Checks, if actual is not not a number (NaN).

isBetween

public ExpectDouble isBetween(Double start,
                              Double end)

Checks, if actual is between start (inclusive) and end (exclusive).

Mathematically start ⇐ actual < end.

Parameters:

start - Interval start (inclusive).

end - Interval end (exclusive).

isNotBetween

public ExpectDouble isNotBetween(Double start,
                                 Double end)

Checks, if actual is not between start (inclusive) and end (exclusive).

Parameters:

start - Interval start (inclusive).

end - Interval end (exclusive).

check

protected T check(boolean cond,
                  String msg,
