shouldBeWithin

fun LocalDateTime.shouldBeWithin(temporalAmount: TemporalAmount, date: LocalDateTime): Unit

Asserts that this is within temporalAmount of date

Verifies that this is within temporalAmount of date. For example, 09/02/1998 10:00:00 is within 3 days of 10/02/1998 10:00:00, and this assertion should pass for this comparison.

Opposite of LocalDateTime.shouldNotBeWithin

    val firstDate = LocalDateTime.of(1998, 2, 9, 10, 0, 0)
    val secondDate = LocalDateTime.of(1998, 2, 10, 10, 0, 0)

    firstDate.shouldBeWithin(Period.ofDays(3), secondDate) // Assertion passes


    val firstDate = LocalDateTime.of(1998, 2, 9, 10, 0, 0)
    val secondDate = LocalDateTime.of(1998, 2, 25, 10, 0, 0)

    firstDate.shouldBeWithin(Period.ofDays(3), secondDate)   // Assertion fails, firstDate is not within 3 days of secondDate
